Explanation of console messages Message complexes
9.3.4 Failover at the RAID system
SXSD018 shd<k>t<ctl>: Target vanished
or
SXSD015 shd<k>t<ctl>: cmd "Write or Read" @ blk <number> key "Not Ready" (0x02) asc
"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------- 1 root other 76, 13 May 15 15:44 raid100.b
crw------- 1 root other 76, 13 May 15 15:44 raid100.c
brw------- 1 root other 76, 26 May 15 15:44 raid101.b
crw------- 1 root other 76, 26 May 15 15:44 raid101.c
brw------- 1 root other 76, 39 May 15 15:47 raid102.b
crw------- 1 root other 76, 39 May 15 15:47 raid102.c
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)
