Add RAID Controller for host 2nd array

Arakattack_1 — Mon, 21 May 2007 21:06:03 GMT

Hello,

I have SA532 with 2x36gb RAID0 and a MSA30 connected to it with 3x300gb RAID5 harddisk.

It's configured like this
/dev/cciss/c0d0
/dev/cciss/c0d1

What i want to do is adding new controller SA642 to take over /dev/cciss/c0d1.

How to do make it happen?

Do i have to change fstab entry?

Thank you,
Yunata Oct

Sorry forget to mention:
OS: Redhat Enterprises 4
Hardware: HP Proliant ML310G3
1st controller: Smart Array 532
currently managing 2 internal RAID0 scsi disk and
3 RAID5 external disk in external disk enclosure HP MSA30

I want to add 2nd controller which is Smart Array 642 to take over 3 RAID5 external disk in external disk enclosure HP MSA30.

Thank you

New raid controller will auto detect array config attached on the disk. Power down server before installing controller.
