Common scenarios for critical
array status
Unplugging disk that is part of an array
Bad sector detected on a disk part of the
array
Unrecoverable data during rebuilding
Defective port or cable interrupts
rebuilding process
To recover from this situation,
1.
Backup your existing data.
2.
Identify which disk is faulty.
You can refer to the LED lights on the enclosure.
Refer to the WebGUI Logical tab and Event tab.
3.
Re-insert the faulty disk or replace with a new disk.
Array will rebuild automatically if you enable auto-rebuild setting and you
simply reseated the faulty disk.
Note
: Click
Rescan
if array still does not rebuild
automatically.
4.
Once a new disk is added, add the new disk into the critical array.
Log in to WebGUI.
Click
Logical
Tab.
Click
Maintenance
>
Add
disk
> select the appropriate disk.
5.
Rebuild should start automatically.
If rebuild does not start, click ‘Rescan’ on the left hand panel.
Note
: Rebuilding an array takes on average 2 hours per 1 Terabyte of disk capacity.
The process will scan through the entire disk, even if you have very little
used
disk
space.
Rebuild failed
If rebuilding fails to complete due to bad disk sector errors (check in the Event Log),
there is an option to continue rebuilding on error in HighPoint WebGUI.
1.
Log in to WebGUI.
2.
Click
Setting
tab.
3.
Under
System
Setting
, change
Enable
Continue
Rebuilding
on
Error
to
Enabled.
This option will enable rebuilding to ignore bad sectors and attempt to make your data
accessible. It is important to backup immediately after backup is complete and replace
or repair any disk(s) with bad sectors.
