Replacing the raid disks.
I have to replace both disk on compaq BL20 blade (application need more disk space). Currently they are hardware mirrored 2X72GB drives. I want to replace them with 2X146GB.
I have got some idea but i would like to confirm with some of folks here. Here are steps i am thinking :
1. Pull the second mirror drive.
2. insert the new 146GB drive & let it sync with primary disk of 72 gb.probably it would leave rest 72 gb as unused space.i should be able to partition that space using fdisk.
3. once it sync (how to check it? ) try to boot from new 146gb disk. If it goes well insert the second 146GB disk & let complete sync.
Raid controller is compaq cciss. Enclosed output of fdisk :
[root@fcold1 dev]# fdisk -l /dev/cciss/c0d0
