SXSD018 shd<k>t<ctl>: Target vanished
or
SXSD015 shd<k>t<ctl>:
"Drive Not Ready" (0x04) ascq 0x02
WARNING
followed by
SXVD004 vdrv<n> (FAILOVER): int switching
SXVD001 vdrv<n> (FAILOVER): switch 0:4->1:5
but not followed directly by another "switch" message.
Meaning
Normal failover. If one of the two RAID controllers (each CX500/CX3-20 has 2 of them) or
the corresponding cable fails then this message sequence is displayed.The RAID disk array
involved is the disk array with the next highest minor number:
Example (vdrv6)
$ 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 vdrv6. Therefore the
RAID disk array involved is raid100.c (minor number 13), i.e. the first RAID disk array.
(Compare 6 of the vdrv with the minor numbers)
Response
Notify maintenance staff.
