Scripts to web publish HMC managed systems configs

2 Quick scripts (shell & expect) to grab configs off HMCs for managed IBM POWER(aix/linux/vio)systems and format them into a html web page.

Will work where no ssh trust exists (ie Where you cant run mkauthkeys -u lpar2rrd -a 'ssh-dss ....' as hscroot)
If ssh trust exists then the script does not need the hmccli expect script

Script renders HTML to stdout so just redirect eg ./$0 > index.htm

<br />#!/bin/bash <br />############################################################################################# <br /># This script runs commands on HMCs and formats the output into HTML tables to stdout # <br /># CJR Feb/2011 # <br /># -calls hmccli that needs expect and hardcoded RO HMC user # <br />############################################################################################# <br />table() <br />{ <br />awk '/login/||/Pass/{next};!/Server/&&!/hmc/{print}'|sed 's/^/<TR align=left><TH>/'|sed 's/:/<\/TH><TH>/g'|sed 's/.$/<\/TH><\/TR>/' <br />} <br /> <br />for i in 1 2 3 4 <br />do <br /> hmc=hmc$i #hmc1 hmc2 hmc3..... <br /> /data/config/hmccli $hmc 'lssyscfg -r sys -F name' | grep Server > ${hmc}Machines <br /> echo 'HMC='$hmc <br /> for mach in $(<${hmc}Machines) <br /> do <br /> echo '<big>Frame Level CPU</big>' <br /> echo '<TABLE BORDER=1 CELLSPACING=0 CELLPADDING=2 WIDTH=90%>' <br /> echo '<TR><TH>'$mach'</TH></TR>' <br /> /data/config/hmccli $hmc "lshwres -r proc --level sys -F configurable_sys_proc_units:curr_avail_sys_proc_units:pend_avail_sys_proc_units:installed_sys_proc_units --header -m $mach" |table <br /> <br /> echo '<TABLE BORDER=1 CELLSPACING=0 CELLPADDING=2 WIDTH=90%>' <br /> echo '<TR><TH>'$mach'</TH></TR>' <br /> /data/config/hmccli $hmc "lshwres -r mem --level sys -F configurable_sys_mem:curr_avail_sys_mem:pend_avail_sys_mem:installed_sys_mem --header -m $mach"|table <br /> echo '<big>Frame Level Memory</big>' <br /> <br /> echo '<TABLE BORDER=1 CELLSPACING=0 CELLPADDING=2 WIDTH=90%>' <br /> echo '<TR><TH>'$mach'</TH></TR>' <br /> /data/config/hmccli $hmc "lshwres -r io --rsubtype slot -F unit_phys_loc:phys_loc:lpar_name:description --header -m $mach"|table <br /> echo '<big>Frame Level Slots</big>' <br /> <br /> echo '<TABLE BORDER=1 CELLSPACING=0 CELLPADDING=2 WIDTH=90%>' <br /> echo '<TR><TH>'$mach'</TH></TR>' <br /> /data/config/hmccli $hmc "lshwres -r proc --level lpar -F lpar_name:curr_min_procs:curr_procs:curr_max_procs:pend_min_procs:pend_procs:pend_max_procs:run_procs --header -m $mach"|table <br /> echo 'LPAR Level CPU</big>' <br /> <br /> echo '<TABLE BORDER=1 CELLSPACING=0 CELLPADDING=2 WIDTH=90%>' <br /> echo '<TR><TH>'$mach'</TH></TR>' <br /> /data/config/hmccli $hmc "lshwres -r mem --level lpar -F lpar_name:curr_min_mem:curr_mem:curr_max_mem:pend_min_mem:pend_mem:pend_max_mem:run_min_mem:run_mem --header -m $mach"|table <br /> echo '<big>LPAR Level Memory</big>' <br /> <br /> done <br />done <br />

Openssl 0.9.8 benchmark on power7 3.5GHz AIX 6.1TL5 SP1

cop that CAT!

POWER7 models and AIX (from IBM dW)

These are the minimums but higher service packs are recommended.

AIX 7.1 TL00	*	*	*	*

Notes:

1. AIX 6 is highly recommended as the default install to ensure simple updates (you will then avoid the upgrade to 6.1, as AIX 5.3 is eventually phased out).
2. - means this combination is not supported.
3. * means no service pack needed ... but I always recommend adding the first service pack (as soon as it is available) to avoid early problems that are already fixed.
4. AIX 5.2 TL10 SP8 is supported via AIX7, POWER7 and Versioned WPARs.
5. Other AIX releases and Technology Levels are not supported.

Oracle Siebel 8 support on IBM AIX6

AIX 6 and Siebel version 8.0.0.10 will play together,AIX 6 and Siebel version 8.0.0.5 or below will not, AIX 5.3 TL12 may be the best option for support longevity.

.......more generally

$echo AIX $(($(date +"%Y")-2003)) on POWER $(($(date +"%Y")-2003))

I saw on insidehpc.com that NCSA/IBM dont run AIX on there biggest POWER7 HPC cluster systems anymore, eg Blue Waters http://www.ncsa.illinois.edu/News/10/0322Linuxselected.html

All new power7 p770s

We bought 3 3CEC IBM pSeries p770s a few weeks back- first in Australia me thinks

Its the end of model run out sale!!

Upgrading power5 p595s to power6+ 5Ghz ,power 595s (9119-FHA http://publib.boulder.ibm.com/infocenter/powersys/v3r1m5/index.jsp?topic=/iphdx/595_fha_landing.htm ) has got to be a great bang for buck upgrade.

P595's have no end of life against them yet and the power6+ processor books have dropped in price almost 50% (eg http://www.theregister.co.uk/2010/03/18/ibm_power_595_cuts ) and a 64 core p595 upgraded with 5GHz p6+'s is about as powerful as a new power7 3.5Ghz 64 core p770
eg
System Name SPECint_rate20063 SPECfp_rate2006
IBM Power 595 2160 2180
IBM Power 770 2013 1689
ref http://www-03.ibm.com/systems/migratetoibm/systems/power/performance.html

(so you can still consolidate a lot more eggs into the same basket if thats your aim) and p595 has better RAS eg no single p5ioc chip handling both GX++ ports ie loosing the wron p5ioc kills all IO on the CEC - this was the case with the p570's too)

power6+ can do all the multiple shared pools(oracle savings), VIO, AIX6.1, WPAR, live partition mobility, micropatitoning, active memory sharing (not active memory expansion(Trade CPU for RAM) or max/turbo/intelli core that all sound a bit multimedia cdrom come MMX technology to me)

p595s can be upgraded to power 595s with just new power6+ books - no need to change anything else its what Auspost did - just by adding the new power6+ books you can free up lots of space (consolidating) and gain all of the good power7 features without increasing your footprint 1RU https://www.ibm.com/developerworks/aix/library/au-upgrade_power6/ (Chris Gibsons experience)
