In case, you did not notice (as its the silly summer season) AIX 7 is shipping in 19 days time. See the official AIX 7 Announcement Letter for all the details This is a whole 2 months early - well done guys.
March 11, 2007, marks the start of Daylight Savings Time this year. At 2 a.m. on Sunday, the time will officially "spring forward" one hour. Patches to HMC code have been available on the HMC home page: https://www14.software.ibm.com/webapp/set2/sas/f/hmc/home.html What happens if you haven't updated your HMC by the time DST begins? Will there be an impact on the managed serves? The HMC will not stop working, and neither will the managed servers. The time can be reset manually on the HMC. This will entail rebooting, but again, this has no... [More]
LPARmon Version 2 is now available from IBM Alphaworks. This free tool provides a graphical interface for viewing partition performance. The tool was developed by Austin's Briefing Center to demonstrate Advanced Virtual Partitioning, in particular to demonstrate free pool utilization in a micropartitioned server. I highly recommend it. http://www.alphaworks.ibm.com/tech/lparmon?open&S_TACT=106AH62W&S_CMP=NEWS
I have tried to get permission to pass on these numbers publically but got no answer at all. As these are facts rather than opinions, I see no harm in them. So I will work on the old theory: "it is easier to ask for forgiveness than permission" ... here goes. The AIX Virtual User Group often asks a few questions as part of the registration process for the next webinar session and it generates fascinating statistics from real POWER and AIX users. Observations: The people that join the AIX Virtual User Group are well above the... [More]
I use the following formula to size the minimum number of cores on replacement servers. The formula is based on "used" performance on the installed servers matching "used" performance on the replacement server. c2 = (u1)(c1)(p1) / (u2)(p2) Where c1 = # cores on the installed server p1 = "performance per core" of the installed server u1 = % utilization of the installed server c2 = # cores on the replacement server p2 = "performance per core" of the replacement server u2 = % utilization of the replacement server If consolidating multiple...

Update Version 14: Just release version 14 (17th March 2016) Changed format a little in light of experience of uploading to the Work Load Estimator Changed to official Column header line Note: it is mandatory to include the header line generated but nmon2WLE -c The online IBM WLE tool needs a specific string to identify the System = the web tool pops-up the list for you to select from. Unfortunately, these strings and user friendly server names ( like Power Systems E850) are not available within AIX so nmon reports just the System Model:... [More]

If you're planning to upgrade the microcode on your p590/p595 system, I recommend waiting for the 153 version which should be out soon. (The current version is 150, Nov 2005) If you have already planned an outage for the upgrade, I would consider downloading the 153 ISO image from the server located in Boulder. open a DOS window ftp testcase-blue.boulder.ibm.com enter 'anonymous' as the id enter 'your e-mail address' as the password cd /hardware/fromibm/9119/ bin mget 01SF230_153_120.iso Be sure to check the prereq's before upgrading: -...
