We recently had a round of proactive maintenance which upgraded our PS6200 SANs to Firmware V8.1.1 and our SAN HQ to version 3.1.0.7890.
SAN HQ is now throwing error 4.2 (at caution, warning and critical) saying all of the Volumes in the Groups are running at high in-use space levels (varies between 88% and 98% depending on the Volume). Running the Group Manager tool shows that these Volumes are in fact not running at these levels and are well below any usage threshold that would trigger an alert.
I've tried re-installing SAN HQ and re-registering the Groups in it, with no luck. I also tried increasing Volume sizes, which also has no effect. All the Volumes are Thin Provisioned.
Any information or help is gratefully received.
