Error on Cluster - Bus reset

Has anyone come across any of the following errors or can recommend any advice?
We have 2 Proliant DL380 servers set up with an array storage as cluster.

Cluster service is requesting a bus reset for device \Device\ClusDisk1Part0.

The driver for device \Device\Scsi\cpqcissm1 performed a bus reset upon request

Re: Error on Cluster - Bus reset

I wouldn't worry about this. A SCSI bus reset is a normal part of how a cluster takes conrol of the disks. If it was an informational message (vs. an actual error) in the Event Log, I wouldnd't worry. If it was an actual error, it's still no big deal, as it probably means that one of the nodes was taking control of the Quorum drive.

Thanks,

Re: Error on Cluster - Bus reset

I get this problem on startup along with the error
Cluster service is requesting a bus reset for device \Device\ClusDisk0

the node comes back online but is unable to access the disks, and therefore is no use in the cluster...

Re: Error on Cluster - Bus reset

Which SmartStart (PSP) version you use?
AFAIR, in v.7.1 insight diagnostic driver issue similar false warning.

Re: Error on Cluster - Bus reset

Not sure which version i use, windows reports the error.
All the logical drives are found ok in the array startup but not in windows.

1 have 3 clusters
1 group of two works correctly

the other 2 groups of 2 clusters, 1 server on each has this error report on windows startup.

I presume i need to power down the cluster and try reattaching the "broken" node to the disks by itself, to see if it can access the disks...

I don't want to screw up the cluster though, as the broken node attaches to the shared disks, i presume this won't cause any issues on the shared disks?
