PS6100X Storage Pool capacity Alerts

Hello Darren, 

 Can you be a little more specific?   I'm guessing this alert is coming from SANHQ?   If so then most thresholds can be modified. 

 If from the array, is it complaining about a volume or the group?   Posting a screenshot of the error would be helpful. 

 Regards, 

Don 

Hello Don,

It's coming via an email alert from what appears to be the group itself.

WARNING event from storage array SWYT-PS6100X-3

subsystem: MgmtExec

    event: 8.3.65

     time: Thu Sep 22 00:00:00 2016

Free space is below threshold of 15 percent for pool AutoTier. Default Snapshot Schedule will run with max-keep set to 1.

Hello, 

 OK, this makes more sense.  If you look at the last sentence, it's actually referring to the "Default Snapshot Schedule"   It's not worded greatly..  

Another way this could be written is:

 "Because the freespace is below 15%, the Default Scheduler will only keep one snapshot" 

A new feature in 8.x, is a system snapshot schedule that runs at Midnight, with a max keep of 2. 

So any volume that has snapshot reserve, but does not already have snapshots, the system will create one for you.  It's very similar to a feature in Compellent,, which inspired this. 

 At the CLI, you can change the time, or disable that default snapshot schedule. 

GrpName>grpparams default-snapshot-sched ?
disable - Disables the default snapshot schedule.
enable - Enables the default snapshot schedule.
show - Displays the current values of the default snapshot sche
dule.
start-time - Set the default snapshot schedule's start time.
GrpName> grpparams default-snapshot-sched disable

If you not using snapshots you can also set the reserve on each volume to zero.  This will return that space to free space. 

Regards, 

Don
