You should have no problems doing this, provided your boot media is set up correctly…

BWith a “standard’ RAID 5 setup (whatever that means), you will have a minimum of three (3) drives, with parity information striped across the equivalent of one drive. What I mean is that if you are using three 100GB drives, you will have 200GB available space – the balance is dedicated to the array’s parity information. This allows for a drive failure without data loss.

Most HBA’s (Host Bus Adapters), whether IDE (old…..), SATA, SCSI or SAS also allow for one or more hot or warm spare drives: with a hot spare, the array will automatically initiate a rebuild if the array experiences a drive failure. With a warm spare, you actually need to kick off the rebuild manually, but the spare drive is already there in the enclosure.

RAID 6 utilizes the equivalent of two parity drives (minimum or four (4) per array).

All of this is basic storage theory…

If you are using Ghost (or some other imaging product) for disaster recovery or backup purposes, you will most likely be booting from a “live” CD. You will either need to make sure that your HBA drivers are available during boot by integrating them into the boot process, or by supplying them BY MEANS OF FLOPPY DISK (hey, I don’t make the rules) during CD boot. The HBA then presents your new/reworked/replacement disk pack / array to the operating system as a logical drive and the reimage / restore can then proceed.

Be aware that with Ghost in particular, there are switches/settings/configuration options you need to be aware of, or your restore may fail…
