How to destroy hardware raid on T5120
Hi,

I have problem creating hardware raid on T5120 with 4 disks. After the hardware raid 1 created, then I used the raidctl -l c1t0d0 and raidctl -l c1t2d0
the output of volume c1t0d0 contain disk 0.0.0 0.1.0, also the volume c1t2d0 contain disk 0.0.0 0.1.0 and should be 0.2.0 0.3.0

so I destroy both volume and then i issued command raidctl, the out shows controller 1 with disk 0.0.0 0.1.0 0.2.0 0.3.0, I thought output should be no raid volume found.

Anyone knows how to complete destroy the hardware.

Thanks for your help!

have you booted from cd/dvd or from internal disk?

Yes. I booted to single user mode from DVD. Then created the raid 1 from the four 146GB disks. Here is the output:

                0.1.0   136.6G          GOOD

so my question is how come the volume c1t2d0 disk list same as volume c1t0d0. I thought that volume c1t2d0 disk list should be 0.2.0 and 0.3.0

Thanks!

what is the output of "raidctl -l" without any further options?

Here is the output of raidctl -l

# raidctl -l
Controller: 1
Volume:c1t0d0
Volume:c1t2d0
Disk: 0.0.0
Disk: 0.0.0
Disk: 0.0.0
Disk: 0.0.0
......
then this output Disk: 0.0.0 keep printing on screen

Thanks!

looks like there is something slightly wrong Smilie. try to give the disks a new label with "format -e". also check the firmware for the mashine and the raid-controller. in case you are downrev, please update.

to destroy , use:-
raidctl -d c1t0d0
raidctl -d c1t2d0

example:
# raidctl -d c0t0d0
RAID Volume 'c0t0d0' deleted
