Replacing disk on a E3500

[dandan123]

The boot disk mirror on a E3500 has failed. It's under veritas control and I'm familiar with the veritas commands to take it offline.

luxadm does not show this disk, I'm guessing because the drive is no longer responding.

Is it ok to take it off veritas and then pulling it off ?

First I cd /dev/dsk and run an ls -al on say c0t1d0s0
to confirm the path and wwn#

Then after I do the procedure below I will again run ls -al on /dev/dsk/c0t1d0s0 and confirm that the WWN showing is the new drive WWN.

This is the procedure I usually use;

1. Inform Volume Manager you wish to remove the disk

vxdiskadm option 4 (Remove a disk for replacement)

2.Take the disk offline

vxdiskadm option 11 (Disable (offline) a disk device)

3. Remove the device entries, the following command will complete this

luxadm remove_device <logical path or physical path or WWN ...>

4. Replace the disk, then

luxadm insert <no arguments required>
or luxadm insert_device <logical path or physical path or WWN ...>
5. Inform Volume Manager of the new device

vxdctl enable

6. Bring the disk back online

vxdiskadm option 5 (Replace a failed or removed disk)

Thanks

forgot to mention that you do not want to remove the bad drive until after you have run step 3. This step will remove the paths for the specific drive then tell you to it is ok to remove the drive.

Thanks for the detailed procedure.

Unfortunately the Sun tech replaced the drive when I wasn't around so I'm not sure what he did but the drive is up now.

Thanks.
