Setting RAID level
RAID level is set using the RAID level
selector on the rear panel of the
subsystem. The RAID level selector
consists of two switches. The four
possible combinations of switch position
correspond to the four available RAID
settings: 0, 0+1, 5 and 5+spare.
If the RAID level is not matched
between the disk setting and the
RAID level selector setting, the LCD
will display the following two
messages alternatively:
(1) “RAID level”
“Unmatched”
(2) “Current: Rx”
“Original: Rx”
Note:
Current Rx means the RAID
level setting of RAID level selector
Original Rx means the RAID level
setting of current disks
For example:
Supposed the RAID level selector is R0, but
the disk setting detected from disks is R5, the
LCD will display the following two
messages alternatively:
(1) "RAID Level"
"Unmatched”
(2) "Current : R0"
"Original :
R5
"
Solution:At this situation, RAID cannot
work, users should choose one of the
following options :
(1) Shut down and tune the RAID
level selectors to R5.
OR
(2) Re-plug the four disks and
re-create the Array to R0 (But data
in the R5 disks will be lost due to
the destructive initialization)
