Disabling EMS for LUNs in an EVA

[Andre Stewart]

In the release notes for SecurePath 3.0E, on page 15, it states:

"Disable the Event Monitoring Service (EMS) for all of the devices/LUNs in an EVA."

How does one go about this? I would assume it involves adding entries to the /var/stm/data/tools/monitor/disabled_instances file, but I can't find any information to confirm that assumption.

Would I add something like:
/storage/events/disks/default/255_255_* to the file?

Run this program and it should be able to help you out:

/etc/opt/resmon/lbin/monconfig

[Andre Stewart]

Okay, I've run that program many times, but there are not hints as to whether or not specifying the hardware paths I mentioned above is the proper thing to do in order to support SecurePath. Could you give me some more details?

Andre,

1. STOP diagnostice.

2. You will have to add all those disks in disabled_instances file as follows.
/storage/events/disks/default/0_4_0_0.3.11.0.0.0.2

Add all disks for which you do not want EMS monitoring.

3. Once added, do monconfig and enable monitoring.

Andre,

What version of the OnlineDiags do you have? I'm not sure this should be necessary with a recent version.

If you run 'cstm' that will show the version number.

When you run 'monconfig' and 'Check', do you see the entries listed for the EVA LUNs?

1.) Thanks for the procedure. The statement in step two was what I was looking for. I wasn't sure if I could use the regex wildcard "*". It's implied on page 16 of the SecurePath 3.0E Release Notes, but I wasn't sure.

2.) cstm outputs:

Support Tools Manager


Version A.47.05

Product Number B4708AA

Hi Andre

Run the following command to make changes in EMS:

#/etc/opt/resmon/lbin/monconfig

Yes, wildcards are supported in the disabled_instances file, so that example should work.

Also, I believe the problem with SecurePath that the use of disabled_instances is meant to work-around was meant to have been fixed in version 3.0C of SecurePath, so the documentation in 3.0E may not be up-to-date.

Have you actually seen any problems with SecurePath, or are you just following the instructions?

Just following instructions. We recently installed it and I was trying to avoid any unnecessary notifications/ISEE tickets.

So, basically the soultions are:

1.) Do nothing, it is unnecessary with versions of SecurePath newer than 3.0C

2.) Wildcards are valid, if you need to use them.
