Regarding SCSI Raid, Striping with Parity

[PlatinumGold]

can i use the HD's in another scsi system and rebuild the same volume?

With the identical controller card, possibly.

Why would you need another system anyhow? RAID 5 can eat a lot of drives before actually failing. Just keep spares on hand.

because the system is failing. i have data i need on it (and don't start with the backups. i know i know.

It depends on where the container info is stored.. Some systems (Dell) put the container info on the hd's while other put the info in the raid controller's bios.

What's failing ?? hd's ? If its hd's then add some addl. hot spare's ..

I am under the impression that raid 5 can only handle 1 drive failure.

Some controllers let you configure 'hot spare' drives that will let the array tolerate multiple failures (however, if a second drive fails during the rebuild for the first drive that failed, you're still screwed). This is normally found only on larger enterprise-class controllers (where you might be running multiple arrays on one controller, and then the hot spares can be used for either array). But, yes, normally RAID5 only allows a single drive to fail before losing data integrity.
