9.3.3 Failure of RAID systems

SXVD001 vdrv<n> (FAILOVER): switch 0:40->1:41
SXVD001 vdrv<n> (FAILOVER): switch 1:41->0:40
SXVD002 vdrv<n> (FAILOVER): Error exit 0130002A E54EC000
Meaning
Both RAID controllers have failed. A failover (1st line) and switchback (2nd line) have been
performed but both without success; the RAID disk array with the next highest minor
number can no longer be accessed.
Example for vdrv3
The error message is:
vdrv3 (FAILOVER): Error exit 0130002A E54EC000
The directory of the vdrives has the following contents:
$ ls -l /dev/vdrv
total 0
brw-------
crw-------
brw-------
crw-------
brw-------
crw-------
The minor numbers here are 13, 26 and 39. The error was reported by vdrv3.
The next highest device is always decisive. Therefore the RAID disk array involved is
raid1.st1.fo.c (minor number 13), i.e. the first RAID disk array.
Only an error which occurs exactly on a minor number (i.e. here on vdrv13) is forwarded. If
required, errors on other subordinate devices will be corrected elsewhere by means of con-
figuring or restarting the IO.
Response
Notify maintenance staff.
