ICP RAID Console
a so-called hot fix (
hot spare
) drive has previously been assigned to a disk array with
ICPCON, the controller will automatically replace the defective drive and start the
reconstruction of the data and the redundant information. Therefore, under these
circumstances, the
fail
state is only temporary and will be eliminated by the controller
itself.
Note:
If a RAID4 or a RAID5 array drive is in the error state and the firmware boots, you will
see an error message as shown below.
"RAID-5 Host Drive 1: Multiple drives have failed"
"Array is in ERROR state and read only"
"Check disks, cables, termination, termpower, LVDS operation,
power supply, etc."
If the array drive can be patched to fail state (all member drives are available; only the one
which failed first may be missing) the following messages are displayed:
"If the problem is resolved you can choose 'y' to patch the array
to fail state (y/n)"
Entering "y" results in a patch to fail. The default behavior is performing the patch.
If the patch was successful, the array status is set to Fail/Patch and the following message
is displayed:
"Patching the array drive was successful"
If the patch failed, the following message is displayed:
"Patching the array drive was not possible"
If the patch was not performed or if the patch failed, the following messages are
displayed:
"Use the controller setup program to analyze the problem"
"Press RETURN to continue"
Rebuild State
The disk array will assume the
rebuild
state after the automatic activation of a hot fix drive
or after a manual replacement carried out with ICPCON. The data and the redundant
information are reconstructed and stored to the new drive.
Expand State
If the capacity or RAID level of an existing disk array is changed, the disk array changes
its state into
expand
. As soon as the expansion or migration is completed, the state
changes back to
ready.
