Daily snapshot alarms on replicated volume

hux — Tue, 28 Nov 2023 23:03:10 GMT

Production Nimble: CS7000, software version 5.2.1
Backup Nimble: CS700, software version 5.0.10

I'm replicating a volume collection from the production SAN to the backup SAN. Every day, the backup SAN throws the following error about one of the volumes in that collection:

WARNING: Volume snapshot space usage over warning limit

On the destination Nimble, the snapshot part of Administration -> Space is set as follows:

Snapshot Reserve: 0
Snapshot Quota: No limit
Snapshot Warning: 0

As I understand it, that basically means "Don't send me alerts about the amount of space snapshots are using."

Also, the production SAN no longer has those configurable options.; they were removed as of version 5.2.1. (The volume in question was created back when that SAN was on version 5.0.10, however.)

So, the obvious question: why is this daily alert getting triggered? And more importantly, how can I stop it?

Hi hux

You may retrieve the alarm ID by running the following command:
alarm --list

To Delete the alarm:

alarm --delete <alarm_id>

if there is no space issue then Removing the alarm will resolve this issue.

hope this helps.!!

Thanks Mahesh, I'll try that.

In general, is this a requirement for Nimble, that sometimes you have to manually delete alarms to stop them from triggering, even if the original condition that triggered it is no longer in effect? That's not been my experience with these systems. Maybe this applies to some types of alert and not others?
