Removing SAn storage from a Solaris server without leaving a Solaris signature on disk

[Maveric63]

Hi

What is the correct procedure to be used to remove SAN disks from a Solaris host, destroying the disks and removing any Solaris signatures on the disks.

Example, lets say I am removing a volume, its disk group and all its disks from a Solaris host. This is the way I see the steps

1. Destroy the volume (vxassist -g **** remove volume *****)
2. Remove the disks from the disk group (vxdg -g diskgroup rm ******)
3. Delete the disk group (vxdg destroy *******)
4. Offline the disks that were in the disk group (vxdisk offline ******)
5. Remove the disk from Sf Control (vxdisk rm ******)
6.Stop SF deamon (vxdctl disable)
7. Stop SF EventSource (vxddladm stop eventsource)
8. Remove all SAN disk mapping and masking)
9. Rescan Solaris host for changes (devfsadm -Cv)
10. Rescan Solaris (cfgadm -l)
11. Start SF eventsource
12. Start SF deamon

Disks should now have been removed from the Solaris host and all Solaris signatures removed from disks.

Am I missing any steps

You are missing one step of doing an unsetup (taking the disk out of vxvm control) in between ..

I would suggest that to be a step 4 .

# vxdiskunsetup -C cxtxdx

then u can offline, remove & continue with next steps, rest looks ok to me ..

Hi

If there is sensitive data on the disk, then SFHA 6.0 has the ability to shred it with the vxdiskunsetup -o shred option.

just curious, why do you need to offline the disk before vxdisk rm? why do you need to remove all volume first before vxdg destroy?

i am wondering what is the benefit.
