Avid ISIS Blue Square Event Message:
Dirty Block Threshold Suppressed for Disk 1...Normal Ops...Dirty block threshold reached for disk 1! Beginning backoff...
These two lines filled up an entire page of my System Logs in the ISIS 5500 storage manager.
Has anyone seen this before?
-Kyle
I am seeing this too. Anybody know what it means?
There was recently a big thread on the ACSR line discussing a sudden rise in disk errors for ISIS5500...some were chalking it up to end of life cycle on drives. How long have you had your 5500? We've had ours for a little over 5 years now and have replaced 3 drives, with Dirty Block Threshold errors coming up every now and then for Disk 1. Once the media error count gets high enough I'll probably order a new cold spare but don't know how long we can keep this up if the drives start failing quicker and quicker. Is it time to start looking into NEXIS?
We have definitely seen a lot of bad isis drives lately. Especially, the 4tb ones. This month, between all of our clients, it has been close to 15 drives that we have replaced and it seems like this happens every single month now.
I didn't see any media count errors in the megaraid. There is one drive with 1 uncorrectable error and we recently replaced 3 drives in it.
