Setting RAID level
RAID level is set using the RAID level selector
on the rear panel of ACUTA 4/4S. 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 ACUTA 4/4S 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 )
