09 Jun 10 System I/O layout (EMC specific)
This is a script designed to document the layout of a system. It is EMC specific and requires the output of the inq command, which I store in /tmp/inq.txt
It can however be adapted to non EMC disk systems. It correctly shows the port/lba layout and status of network and fiber I/O the way it appears on the outside of the system. Two tables are included to permit lookups of the port/lba information. It has worked on blades, and is certified for rp8420 and superdome systems.
It has only been tested on HP-UX 11.31.
… please stand by….update in progress…

18 May 10 swlist command to provide install date
New trick learned from HP support backline engineer.
swlist -l fileset -a revision -a title -a state -a install_date

30 Sep 09 SD-UX Locked. Diagnostic steps.
Problem: After being Ignited superman lost most sd-ux functionality.
Note: superman (not its real name) is a vpar running on a superdome complex. Only swlist works, swreg -l depot, swinstall -i, swverify all fail with the same error.
ERROR: “spuerman/”: You do not have the required permissions to
select this target. Check permissions using the “swacl”
command or see your system administrator for assistance. Or,
to manage applications designed and packaged for nonprivileged
mode, see the “run_as_superuser” option in the “sd” man page.
* Target connection failed for “zrtph0v0:/”.
ERROR: More information may be found in the daemon logfile on this
target (default location is
superman:/var/adm/sw/swagentd.log).
* Selection had errors.
Standard techniques say check:
/sbin/init.d/swagentd stop
/sbin/init.d/swagentd start
Check /etc/hosts networking is consistent.
Make sure /etc/nsswitch.conf is present and makes sense.
Check permissions on /var/tmp and all the swagent files.
None of this worked.
swlist -i -s $PWD in a depot generated the following error taken from ITRC because the system is already fixed.:
swacl -l host @ superman
List swacl generates this:
Util_Random internal error: Read of /dev/urandom failed, rv=-1, size=8, No such device (19).
There were a series of other errors all pointing to /dev/urandom
lsdev showed that /urandom did not load the kernel module rng (Randome Number Generator).
Detail root /usr/sam/tui/kc/modulemod.sh rng
Detail root /usr/sbin/kcmodule -a -P ALL
This is normal output. Before the system was fixed the system did not show the module running.
lsdev | grep rng
138 -1 rng pseudo
Fix was to unload the rng module in the kernel (using sam SEP cheats)
Then we loaded it. In spite of being listed as dynamic a reboot was required to restore sd-ux functionality.
Actual source of the problem: Ignite image of supergirl did not exclude the /dev/ “files” This cause the wrong kernel module to be loaded with the /dev/urandom “file” driver. Normally this is not a problem becuase /dev is crecreated but for some reason /dev/udandom was not loading the kernel module rng
Ignite excludes have been updated to exclude these files and the system will be re-ignited to make sure nothing else bad happens.
