Disable EMS for Disk / Fibre Channel

[Justin Willoughby]

I remember someone telling me that if we connect our HP system (K570) to our IBM ESS that we must disable EMS otherwise it will cause problem.

Is this the case?

Can I just disable EMS for disks attached via fibre channel or must I disable the EMS system wide?

Thanks,

Hi Justin,

We have HP boxes connected to a Shark. You'll only have to disable EMS for disk controllers connected to the Shark. You don't have to do that, but EMS complains about all the IBM disks when you do work on the Shark, and it gets pretty annoying if you have lots of disks. One of our other sys admins has posted a reply to a thread about this. Here is the link:

You can actually disable the EMS monitoring for a specific hardware path. You don;t have to disable EMS systemwide. This is how ..
# /etc/opt/resmon/lbin/moncheck
==> Take note of the names of instance you want to disable. For example an instance can look like this ..
/storage/events/disks/default/0_4_0_1.1.0
# /etc/opt/resmon/lbin/monconfig
==> Select (K)ill monitoring option.
# cd /var/stm/data/tools/monitor
# vi disable_instances
==> Add the instance line in this file ..for example ...
/storage/events/disks/default/0_4_0_1.1.0
# /etc/opt/resmon/lbin/monconfig
==> Select (E)nable monitoring option.

Finally run ..
# /etc/opt/resmon/lbin/moncheck

And if you look closely you should see EMS monitoring on that instance is now turned off, it won't log any error in syslog and it won't send any email to root.
