Raid 5 disk compatability

[_dobbo_]

Hi guys - i'm hoping any experts on RAID might be able to help me...

I've got a RAID 5 array in one of our servers that has lost a disk and rebuilt itself from the parity information...


I'm about to send the old disk back to seagate under warranty, but I would like there to be a hot spare in the array until such time as a replacement arrives.

Now I have another spare 79GB Ultra160 SCSI/SCA2/LVD drive but from a different manufacturor... I'm sure I can just pop this into the raid array and then use the admin tools to spin it up as a hot spare - is there any reason not to do this?

Or anything I need to check before I do?

Thanks for any help!

It'll be fine as long as there's enough bytes on the disc (there should be, most RAID5 systems allow for a bit of variation).

Thanks! I'll give it a try...

You should be able to use any disk larger than the smallest disk in your array.

There will be a performance hit, but thats better than a failiure
