Scsi Raid
You are Thinking Raid 5 - or Have a Raid 5 Failure Need Data Recovery?
But did you know:
If two disks fail the raid has failed
Most complex controller design
Difficult to rebuild in the event of a disk failure (as compared to RAID level 1)
<b>*Questions for the reader: <b>
How many drives have failed? are they logical, electrical or physical
failures. Are the drives a matched set. Do you know if the failure of
the two drives was at the same time or has one drive failed and the
second went out at a later date?
Keep the order of the drives - number them before removing any drives. This will cut down recovery time as this could be a 4 or 5 drive Raid and have many combinations if we do not have the drives in correct order.
Has the Raid been reinitialised? - if not DO NOT allow a reinitialisation
Are you able to supply the Raid controller?
Capacity of the drives (how many GB for each drive)
What type of drives (IDE ,SCSI, SATA)
Block Size used? (offset of starting block)
Details - additional RAID information - this could be getting in touch with the technician who set up the Raid - looking up any paper work left by a former employee. Then a list if possible of what the RAID holds file ext. ,database names, what makes this RAID 5 so important to recover.
