Hi,

We have an AS 800 running 5.1A PK6 with an RA3000/HSZ22 attached to it. The RA3K has 5 18 gb disks (DSRZ1ED-VW) in it (2 empty slots). Of these 5 - 4 of them are being used as a RAID5 Array and the 5th is a hot spare. Since this is no longer a production box and we are short on disk space we're thinking of converting the hot spare to be part of the RAID5. Longer term we would like to populate the 2 currently empty slots with new drives.

Two questions:

1 - Can I just add the hot spare to the raid5 set without having to reconfigure the raid set?

2 - Longer term: for raid5 do I have to use the same size drives (18 gb) or can I add 36 gb drives into the raidset?

Thanks alot!
Andy
