[Info-vax] Using MSA$UTIL to online maintain logical disk units?

[Rod Regier]

Neil:  In response to your diary.

I wrote a DCL procedure that dumps MSA$UTIL and SAS$UTIL status
to a file and searches for key phrases that things are going south
on RAID logical units.
If it detects issues it sends out an email alert.

Since we supply the procedure as part of our operations package I can't
quote the whole thing here, but here are the key search strings:

 "failed","recovery","Degraded"

I wrote another one to monitor the status of RAID controller batteries
so I can detect their failure and replace them too on detection.
That is especially pronounced on the SA6402 units.

Unreplaced failed RAID cache batteries disables Battery-backed write caching.

I think the RX2800 RAID controller uses super capacitors so batteries
are a thing of the past on that product model.
