Hardware

Got 4 disks in my system. Solaris installed on disk2. Others not used.

So, did :- raidctl -c c1t2d0 c1t3d0

Now it looks like t3 has disappeared now when I do format (as expected). Output of raidctl is-

bash-3.00# raidctl
Controller: 1
Volume:c1t2d0
Disk: 0.0.0
Disk: 0.1.0
Disk: 0.2.0
Disk: 0.3.0
Controller: 2

However, the strange thing is if I do raidctl -l c1t2do its reporting the volume size as 744Mb

raidctl -l c1t2d0
Volume Size Stripe Status Cache RAID
Sub Size Level
Disk
----------------------------------------------------------------
c1t2d0 744.9M N/A SYNC OFF RAID1
0.2.0 744.9M GOOD
0.3.0 744.9M GOOD

Since both disk are 146Gb I assume the volume size would 146Gb?

Also, since these two disks are now mirrored (or will be when the sync completes), if I get a disk failure what happens?

At the moment boot-disk is set to disk2. Will this still work if say physical disk2 fails but the mirror disk3 is still up? Or would I then need to boot from disk3?

Alternatively, could I remove a faulty disk2, replace disk3 int disk2 slot and still boot disk2?
