hardware changes and EMS (HSEE)

[Jesse Breaker]

Hi Guys.. I wanted to know if you install EMS or HSEE and then say 1 or 2 weeks later you remove a part (say your SAN connection) permenantly, how can you get EMS/HSEE to stop reporting that there is a failure with your SAN connection? In other words is there a way to issue a "rescan" of the hardware inventory to update it's database?
Thanks

You can actually disable a particular hardware path from being monitored by EMS. Don't know about SAN but I have tested this on an individual disk and it works. The file that you need to modify is "disable_instances".It's in /var/stm/data/tools/monitor.
# /etc/opt/resmon/lbin/moncheck
==> First take note of the name of instances you want to disable.
# /etc/opt/resmon/lbin/monconfig
==> Choose "K" to kill or stop the process.
# cd /var/stm/data/tools/monitor
# cp disable_instances disable_instances.org
# vi disable_instances
==> From the instance lets say you want to disable the instance ..

/storage/events/disks/default/0_6_0_1.2.0

which represent the hardware at path 0/6/0/1.2.0 , all you would do is add that line /storage/events/disks/default/0_6_0_1.2.0 right at the bottom of the file. Save it. Then run "monconfig" again and enable the monitoring (ie select "E"). Noe if you run "moncheck" again you should see that the path mentioned has been disabled from EMS.

If you have removed a piece of hardware , the kernel should no longer recognise it, thus should no longer alert? Is the disabling instances used if you wish to disable for a period until problem hardware is removed?

I have just had to start looking at arrays etc this week so have found looking for the answer as always extremely interesting
