Installing a TL is an "all or nothing" operation, meaning that requisites will be added so that the whole TL is installed, and not allow a TL to be partially installed. You should back up your system prior to installing a TL.
So, what happens between service packs? Interim fixes, sometimes referred to as fix packs or temporary fixes, or stand-alone PTFs, are made available for relief until the time that the fix becomes available in a service pack. It's what IBM calls "temporary relief." They are tracked on the system with either the lslpp -L command or emgr -l command.
Security updates, published through advisories, are made available by IBM through subscription services.
Another important concept to understand is the Concluding Service Pack (CSP). The CSP is the final service pack for a TL. It usually contains fixes for critical problems or security issues. The new strategy also includes a longer period of support for each OS TL. Each TL will now be supported for up to a two-year period. This means that you can continue to call IBM support for up to a two-year period (from the introduction to the update) without having to move up to the latest TL. The new server update strategy also promises improved serviceability throughout the life of TL. This is done by allowing you to maintain your operating system by installing service packs and PTFs throughout the entire lifecycle of the TL.
instfix -ivq oslevel -rnUse the lslpp -L command to verify that the patch has been applied.
The IBM Service Update Management Assistance (SUMA) allows you to automate the retrieval of TL and service pack deployments. In this section, you're going to use SUMA to retrieve TLs. SUMA was first released with AIX V5.3. More than anything, SUMA helps the system administrator automate the retrieval of AIX updates, allowing the administrator to get away from the mundane tasks of manually retrieving updates from the Web. Furthermore, it allows you to configure policies to automatically download either entire TL upgrades, service packs, or even interim fixes. The primary objective of the utility is to allow systems administrators to spend more time on proactive systems administration and less time on redundant or tedious work such as downloading updates.
So, how do SUMAs work? Essentially, they use a scheduling module that allows policies to be run at predefined intervals, which conform to your maintenance window. The policies can be configured easily without any extensive configuration. You even have the option to manually run SUMA (either from smit or the command line) to bring in whatever updates you require. To configure SUMA, you need to know the fix type. There are eight different kinds of fix types. They include APAR, PTF, Critical, Security, I/O Server, Latest (all fixes), Filesets (specific types), and Maintenance Levels. In addition, there are three types of actions you can perform on a policy. These include preview, download, and download and clean. Preview mode does not really do anything; it just generates a preview of what would be downloaded. The "download only" action downloads the actual data, while the "download and clean" action removes filesets no longer necessary after a new fix level has been brought down. This limits the size of the data that you'll need to keep.
You can run the suma command from either smit or the command line. In the first example, use smit to download an entire TL: # smit suma.
When the smit screen comes up, choose Download Updates Now (easy) and click Enter.
From this screen, scroll down to Download Maintenance Level or Technology Level and click Enter (see Figure 2).
At the window in Figure 3, click F4 and choose the appropriate TL level.
In this case, it is 6100-01, as shown in Figure 4.
This provides you with the following summary:
Now try it from the command line. In this case, you're going to download TL Two for AIX V6.1. Do this by running the suma -x command
After about 30 minutes, it completes successfully
The files get installed in /usr/sys/inst.images, which is where you would also manually put them if you were to retrieve them using different processes.
Why is SUMA important? Perhaps most importantly, it helps to ensure that your systems have the latest patches that it needs. Current fixes are important. Secondly, it downloads the patches without intervention, which allows the systems administrator to focus on more important tasks.
This section reviews Fix Central and discusses how to use it to download TL and service pack deployments. Fix Central is the central repository for all TLs and service packs for AIX. Among other things, you'll see how to log into Fix Central and retrieve service packs. Completely revamped in October of 2007, it provides fixes and updates for all your software, hardware, and operating systems. This includes the Hardware Management Console (HMC). Using Fix Central, you can download using the following options: by APAR, Fix ID, or Test. In addition, there are three download options, IBM Download Director, HTTP, and FTP.
Download a service pack from the exact TL that you downloaded previously during the work with suma from the command line -- 6100-02. First go to Fix Central for System p�, as shown in Figure 8 (see Resources for a link to Fix Central).
From here, in the drop-down menu, choose your version. Another drop-down menu pops up, which is where you can select from one of the following: fix packs, fix recommendations, fix search, managing updates, and security advisories. Choose fix pack. Click Continue (see Figure 9).
From here, select the TL: 6100-02. At this time, you can either download the latest service pack or the entire TL. Choose the entire TL (see Figure 10).
The options for download include Download Director, bulk FTP, or CD. In this case, use Download Director. I recommend this method because it has a friendly interface and there is also flexibility to pause downloads.
The length of time is dependent on your Internet connection. For me, on broadband, this took roughly an hour.
As a systems administrator, the Fix Central URL should definitely be one of your browser favorites. Fix Central helps you keep your systems up to date and is the best method of manually retrieving data for your upgrades. You really can't be an effective AIX systems administrator without knowing how to use this tool.
Now review the procedures to upgrade your system to the next TL.
First log in as root: # su - root. Make sure you back up your system. If you prefer, you can also use alt_disk_install or multibios; the bottom line is that you need to have a plan B if you must go back to your prior level. You should also commit them, because they can't be rejected and they also make it easier to track and reject PTFs.
Do a backup using the following command: # mksysb. When the backup is completed, you're set!
Create a .toc file. This is done by running the inutoc command (see Figure 12). You run this in the directory where your filesets reside. If you don't have the .toc file, your update will not work.
When this is completed, you are ready to start the upgrade. Move to the directory where your .toc file resides. If you do this, you will not have to specify a path name during your upgrade: # smit update_all.
On the screen in Figure 13, you will be making several changes.
For Input device/directory for software, put in the dot (.). If you remembered to cd to the directory that has the .toc file, you don't need to specify the full path name. In this case, you did not commit the software, though as a practical matter because you can't back out of a TL upgrade, you really should say yes to limit the amount of filesets stored on your system -- a real disk hog. In this case, you first previewed the data to ensure that there would not be any problems. This is the third option on this smit menu (shown in Figure 13). The preview option does nothing except validate whether something might be missing as a prerequisite of the upgrade. This is good to do to avoid surprises. You don't want to find out something is missing during your two-hour maintenance window of the month. You can run a preview at any time without any impact to the system.
In our case, as you can see in Figure 14, the preview is successful and there are no failures. So you are ready to move on.
When you are ready to run the upgrade, change the preview to no. You will also have to change the default field that relates to << Accept new license agreement >>. For some reason, AIX defaults to no. Change it to yes.
After you click Enter, it will prompt you to make sure you want to do this. Click Enter to continue to start the process (see Figure 15).
This can run for up to an hour, depending on the speed of your system and the type of upgrade you are performing. When the process is complete, you can scroll down to the summary section to see if you've been successful, which in this case is yes. (see Figure 16).
Your final step is to reboot the box. Make sure you perform this step before bringing your applications back and going live. After I rebooted the box, I ran the oslevel command to confirm the new system level (see Listing 1).
lpar46ml16fd_pub > # oslevel -s 6100-02-01-0847 |
What does this information signify? It tells that you are running AIX V6 TL2, service pack 1, released in 2008 in the 47th week. The forth field, 0847, indicates the year and week. Finally, it is highly recommended that you apply the latest service pack when moving to the new TL. In our case we did not have to, because the latest pack was already a part of the TL upgrade.
TL upgrade deployment schedule
When should you actually perform a TL upgrade? There are generally three scenarios where you will make this choice:
The short answer is that there really is no right or wrong time to perform an upgrade. Some clients need an environment that requires maximum uptime and stability. These clients typically wait until new TLs are out for at least six months to a year before applying them. Other folks will wait for several TL's to be put into place prior to upgrading to ensure maximum reliability. For clients that like to take advantage of new features and ensure that they have the latest security patches, they typically install new service packs shortly after they come out. From a vendor-support perspective, IBM would prefer if you upgraded your TLs (and service packs, for that matter) as soon as they come out. The reason is that it's just easier to support systems that are always at current levels. I like to upgrade at least once a year to a new TL. In doing so, I will also usually wait until at least service pack number two has been released. If you really want to err on the side of caution, wait until service pack number three. That way, you will know that your release is really rock solid.
- You can refer to the following topic in the IBM Systems Hardware Information Center:
Viewing existing firmware levelsTo find out the current firmware level, use one of the following two options. Any user can issue these commands. Upgrading the firmware is a task normally done by the AIX administrator.
- Use the lscfg command
lscfg -vp | grep -p "ROM"Use the lsmcode command. Note that not all AIX versions support this command.

Hi,You might want to start at
http://www14.software.ibm.com/webapp.../aixfixes.html .
Maintenance Levels (MLs) were renamed to Technology Levels (TLs). Service Packs (SPs) are fixes on a specific TL. You can download these from the website, order them on CD or use the SUMA tool in AIX.
IBM has a best practices guide for software maintenance
IBM - Service and support strategy best practices for Power systems
Look into SUMA. I don't know how many machines you have to maintain or how you do your provisioning or what not. But we use SUMA on our 520s and it's great. Every night it downloads the latest patches. We have
a set schedule. We install new patches in the applied state, test them, and just run them as applied until testing is complete and it is time to apply a new round of patches. Then we commit all and apply the
new ones. That's an important step.So give smitty suma a look and see if it helps you out. You will have to do a little work to configure it, but nothing terribly sophisticated. The only information you should need with respect to maintenance levels etc. is your output from oslevel -r.
You may need to use the -c option to suma to add a HTTP_PROXY if you use one. man suma gives good details on this.

Between regular technology levels, IBM will release service packs, PTFs that are grouped together for easier identification. These fixes will be for highly pervasive, critical, or security related issues and will be released ever 4-6 weeks between technology levels.
Applying the latest level of available updates will move the system to the latest service pack. To see which service pack is currently installed, we have a new command switch: "oslevel -s" . The output for a server/LPAR with AIX 5.3, technology level 4, service pack 2 installed would be:
# oslevel -s
5300-04-02Like maintenance levels, service packs are cumulative, so if service pack 4 is installed, all of the previous critical fixes from service packs 1 through 3 will also be installed.
As you might have guessed, this also means the end of "critical fix packs".
Something completely new is the concluding service pack, which will identify the last service pack on a technology level The CSP will contain fixes for highly pervasive, critical, or security related issues, just like an SP, but it may also contain fixes from the newly released technology level that are highly pervasive, critical, or security related.
The CSP will be available shortly after a new technology level is released. As an example, if technology level 5300-04 is released, the CSP for 5300-03, will be available 4-6 weeks later.
It will have a specific level identifier of "CSP", so the "oslevel -s" command output would be:
# oslevel -s
5300-03-CSP
AIX updates are provided as Technology Level packages or Service Packs. These generally available updates have been tested to operate best when all updates in a fix pack are installed. IBM recommends installing the complete fix pack. A fix pack is a combination of many single fixes for product components that are dependent on or related on each other. It can include new features, functions, or enhancements.
Beginning with AIX 5300-06, Technology Levels are supported for approximately two years. End Of Service dates are estimates only. A two year life for a TL is an objective only. All statements regarding

Purpose
Starts the interim fix (interim fix) manager, which installs, removes, lists, and checks system interim fixes.
Syntax
To list interim fix; data:
emgr -l [ -L Label | -n interim fixNumber | -u VUID ] [-v{1|2|3} ] [ -X ]
To install an interim fix package:
emgr -e interim fixPackage | -f ListFile [-w Directory ] [ -b ] [ -k ] [ -p ] [ -I ] [ -q ] [ -m ] [ -X ]
To remove an installed interim fix:
emgr -r -L Label | -n interim fixNumber | -u VUID | -f ListFile [-w Directory ] [-b ] [ -k ] [ -p ] [ -I ] [ -q ] [ -X ]
To check an installed interim fix:
emgr -c [ -L Label | -n interim fixNumber | -u VUID | -f ListFile ] [ -w Directory ] [-v{1|2|3} ] [ -X ]
To mount or unmount an installed interim fix:
emgr -M | -U [ -L Label | -n interim fixNumber | -u VUID | -f ListFile ] [ -w Directory ] [ -X ]
To force removal of an installed interim fix:
emgr -R interim fixLabel [ -w Directory ] [ -X ]
To view packages locked by interim fix manager:
Description
The emgr (interim fix manager) command can be used to install and manage system interim fixes. The interim fix manager installs packages created with the epkg command and maintains a database containing interim fix information. The emgr command performs the following operations:
- interim fix package installation
- interim fix removal
- interim fix listing
- interim fix checking
- interim fix mounting
- interim fix unmounting
- Display package locks
- Force removal of an installed interim fix
Referencing an Efix
The ways to reference an interim fix are as follows:
- Reference by Label
- Each interim fix that is installed on a given system will have a unique interim fix label. This is the unique key that binds all of the different database objects. To reference an interim fix by label, pass the label as a parameter to the -L flag. For example, to run a check operation on an interim fix with label ABC123, type:
emgr -cL ABC123- Reference by Efix ID
- Each interim fix that is installed on a given system has an interim fix ID. The interim fix ID is simply the order number in which the interim fix is listed in the interim fix database. Using this option may be convenient if you are performing operations on interim fixes based on interim fix listings. The emgr command will convert the interim fix ID into an interim fix label before performing the given operation. To reference an interim fix by ID, pass the ID as an parameter to the -n flag.
Note:
Efix IDs can change as interim fixes are removed and added. Always verify the current interim fix ID number by using the -l flag to list the specific interim fix or all interim fixes.For example, to run a check operation on the first interim fix with ID equal to 1, type:
emgr -cn1- Reference by VUID
- Because interim fix packages are not formally tracked by any entity, it is possible that the same interim fix label could be used for more than one interim fix package. However, the emgr command does not accept the installation of more than one interim fix with the same interim fix label at the same time. The VUID (Virtually Unique ID) can be used to differentiate packages with the same interim fix label. The emgr command converts the VUID into an interim fix label before performing the given operation. For example, to list an installed interim fix with VUID equal to 000775364C00020316020703, type:
emgr -l -u 000775364C00020316020703Note:The VUID is displayed in the preview phase of interim fix installation and removal. The VUID is also displayed when listing with verbosity level set to 2 or higher with the -v flag.
Efix Logging
The following operations are logged to the emgr command log file, /var/adm/ras/emgr.log:
- Installation
- Removal
- Checking
- Mounting
- Unmounting
- Forced Removal
Flags
Exit Status
- 0
- All of the emgr command operations completed successfully.
- >0
- An error occurred.
Security
Only the root user can run the emgr command. Efix data, saved files, and temporary files are accessible only by the root user.
The emgr command looks for a supported MD5 generating command on the system. If one is located, the emgr command displays the MD5 checksum to the user. The user can then cross check this MD5 sum with a secured source. If an MD5 generating command is not located, the emgr command takes no further action.
The user can force set the path to an MD5 command by exporting the EMGR_MD5_CMD shell variable. This variable should contain the absolute path to the MD5 generating command.
Note:This feature is not supported in the original release of interim fix management. It is recommended that the user updates to the latest level of interim fix management by updating bos.rte.install to the latest level.
Examples
- To preview the installation of an interim fix package called games.020303.epkg.Z, type:
emgr -p -e games.020303.epkg.Z- To install the interim fix package called games.020303.epkg.Z and automatically expand file systems if additional space is needed, type:

WSG Resources Unix Security Superglue
Superglue is a tool developed by the CITES Workstation Services Group that helps automate the patching of Solaris and AIX machines.Although patching is a crucial step in maintaining system security, it can be slow and tedious work, particularly if you maintain several machines. Superglue was designed to take the burden of patching off of the system administrator, making it more likely that patches will be applied regularly. To use Superglue, all you need to do is mount the Superglue directory on your machine and run the program. Superglue takes care of the rest.
OS | Superglue mount point |
---|---|
AIX | aix-patches.cites.uiuc.edu:/services/patches |
Solaris | solaris-patches.cites.uiuc.edu:/services/patches |
As root:
Please note that the scheduled maintenance period for the Solaris Superglue server is Tuesdays from 1730-1900 (5:30pm - 7:00pm). We strongly recommend that you plan your system patching activities accordingly.
Superglue is provided on an as-is basis and is not officially supported by CITES. Comments on the service may be sent to [email protected].

For AIX, Bull has a check tool that verifies that PTFs corresponding to security problems have been installed. The tool is called "bull_check", and is available from www-frec.bull.com (click on "download").
By default it checks for Year2000 PTFs, give it the option "security" to check for security things.
I have a script to automatically download the missing PTFs from the Bull PTF server, if anybody's interested.
