Updating your PowerHA cluster with cl_ezupdate

cggibbo 270000TMUJ | | Comment (1) | Visits (2474)

Tweet
PowerHA 7.2.1 (June 2017) introduced the cl_ezupdate utility. You can use the cl_ezupdate command to update the software for the entire cluster or a subset of nodes in the cluster, often without disrupting workloads.   https://www.ibm.com/support/knowledgecenter/en/SSPHQG_7.2.2/com.ibm.powerha.cmds/hacmpcmds_whatsnew.htm   You can use this tool to apply and reject updates for PowerHA service packs and technology levels and interim fixes. This process is performed on the entire cluster or on a specific subset of nodes in the cluster.... [More]

PowerVC compatible "ready to deploy" images for AIX 7.1 TL 5 and AIX 7.2 TL 2   “In addition to installation images for AIX, "cloud" image formats are also made available that can be readily deployed with PowerVC. These images contain a default AIX base media install configuration that includes Cloud Init and its dependencies. The images can be obtained from the IBM Entitled System Support website or IBM Passport Advantage. For AIX 7.1 TL 5 SP0 and AIX 7.2 TL 2 SP0, the image files have the following names”.... [More]

Simplifying AIX Live Update with PowerVC

cggibbo 270000TMUJ | | Comments (10) | Visits (7096)

Tweet
Starting with AIX Version 7.2, the AIX operating system provides the Live Update function which eliminates downtime required when patching the AIX operating system kernel. Your application workloads are not stopped, yet they can take advantage of the new fixes immediately after the Live Update operation, without a reboot. Administrators can use the Live Update feature to install AIX interim fixes, service packs and technology levels.   In a nutshell, Live Update allows AIX administrators to install AIX updates in-place, but instead of...

Quick start guide to configuring PowerSC RTC on AIX

cggibbo 270000TMUJ | | Comment (1) | Visits (4393)

Tweet
Using PowerSC RTC to monitor for the deletion of a specific file.   One of my customers was concerned that someone or something was randomly deleting the /etc/niminfo on several of his AIX hosts. We discussed several ways in which he could track down who or what was removing this file. Obviously, the AIX audit subsystem would be an ideal method of capturing this event. However, PowerSC Real Time Compliance (RTC) can also monitor and capture this type of event.   “The PowerSC™ Real Time Compliance feature continuously... [More]

Investigating AIX system crashes with minidump

cggibbo 270000TMUJ | | Visits (6030)

Tweet
The AIX minidump facility was introduced with AIX 5.3 TL3. A mini dump is a small compressed dump that is stored to NVRAM when a system crashes or a dump is initiated, and then written to the AIX error log on reboot. It can be used to see some of the system’s state and do some debugging when a full dump is not available. It can also be used to get a quick snapshot of a crash without having to transfer the entire dump from the crashed system to IBM support.   Please refer to the following, official guide, on " How to examine a...

Automatically backup VIOS configuration changes

The latest release of the VIOS provides a way to automatically backup your virtual device configuration whenever it changes. From the IBM Knowledge Center for POWER8:   https://www.ibm.com/support/knowledgecenter/POWER8/p8hcg/p8hcg_viosbr.htm   "The viosbr command automatically creates a backup, whenever there are any configuration changes. This functionality is known as the autoviosbr backup. It is triggered every hour, and checks if there are any configuration changes, or any other changes. If it detects any changes, a backup...

Migrating you NIM Master to AIX 7.2 using the VIOS VML

cggibbo 270000TMUJ | | Visits (5536)

Tweet
On more than one occasion I’ve written articles and blogs on how to migrate AIX systems to a new version of the AIX operating system. You can find a list these articles (and others) here . Each of the NIM articles focuses on migrating AIX systems (which are configured as NIM clients). The approach is always the same; use a NIM master to migrate the NIM clients to the next release of AIX. What they don’t discuss is how to migrate your NIM master to a new version of the OS. This is the very first step you should take before you... [More]

AIX, LPM & Partition ID sorcery! Why does AIX report that my partition ID has changed after LPM when it hasn't?

I LPM'ed an AIX LPAR from Frame A to Frame B. The LPAR id before the LPM was 99 and after the LPM it's still 99. And the system id has changed, as expected.
