restored.



Rebuild a Disk Group

– If the original group is part of a RAID 5, 1 or 10 disk group, a bad

drive maybe the reason for an orphan classification by the system. If this is the case, make

sure you have a global spare in the system and then use the PIXELSTOR Storage Manager

to do forced discovery of the disk group. Once the disk group is discovered and the bad drive

is identified, the system will start the RAID rebuild using the global spare. This will restore the

disk group.



Re-configure the Drives

– If you cannot complete the disk group or rebuild it, then you will

not be able to recreate the disk group (RASILIENT recommends you always back up your

data to recover from such a scenario). Alternatively you may just want to reuse drives from an

old disk group where the data on the drives is no longer needed. In either case you can create

a new disk group or turn the drives into global spares by using the PixelStor Storage

Manager.

Failure Conditions:



RAID Controller Failure

– When a RAID controller fails in the PixelStor 5000with redundant

controllers, all drives including those on interconnected PixelStor 300e enclosures will

fail-over to the surviving controller.



Drive Failure

– If a drive fails in a RAID 1, 5 or 10 DG, the DG will go into degraded mode. If

a global spare is present in the system, the spare will be automatically added to the DG and a

rebuild of the DG will be initiated. (Note: RAID 0 by definition has no protection and therefore

cannot be rebuilt.)



SAS IO Failure

– When a SAS IO module in one of the interconnected PS300e enclosures

fails, the system will treat all drives associated with that IO module as failed. If only one drive

is missing from the associated DGs the system one rebuild it using an available global spare.

If more that one drive is associated with the affected DGs, all writes to the DG will be

suspended and the DG will be made available to the system in read-only state. Once the IO

module is replaced, the user can use the system utilities to rebuild/repair the affected disk

groups.



SAS Cable Disconnect

– If a cable fails or is removed, the system will react as if the SAS IO

Module failed. (See the SAS IO Failure section above)
