But the Modular Disk Storage Manager shows all disks ok.
The eventlog of the cluster nodes shows at the same time a series of errors, warnings and informations like
The driver detected a controller error on \Device\RaidPort1.
admd1:0:0 Path Failed.
A fail-over on \Device\MPIODisk1 occurred.
Device path information for admd1:0:0:0 has been removed per MPIO notification (object count 1).
What happens with the Storage?
(Sorry for the mix of german and english, but the Storage Manager is in german, the server OS is english)
