Disabled Arrays - HighPoint RocketRAID 4520 Series User Manual

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.
Critical array becomes disabled when faulty disk was removed
If this is the case, check to make sure you removed the correct disk. When you remove
the wrong disk from a critical array, the array status may become disabled. Data is
inaccessible for disabled arrays. Follow these steps to restore the previous state:
1. Shut down your PC.
2. Place all disks, including the removed disks, back to original array configuration.
3. Boot up PC.
4. Once array is back to critical status, identify the correct disk (using the event log)
and replace it.

Disabled Arrays

If two or more disks in your array go offline due to an error or physical disconnection
your array will become disabled.
To recover a disabled array, using the 'Recover Tab' will yield the best results. To
utilize the Recover tab, you will need to insert the exact physical drives that are listed
on the recover list. The goal of using recover is to get the RAID status back to
critical/normal, allowing you to access and back up your data.
Recover with RAID Maintenance
Note: The recover function will only attempt to recover RAID information stored on
your disks. Data integrity of the array will not be fixed, if previously corrupted. All
disks in the original (disabled) array must be detected before performing a recover
operation.
