Removing Disk from server

[Fiona Melody]

Very confused and would appreciate some help.

We have a HP EVA virtual disk attached to a Superdome partition. Removed all logical volumes & volume group associated to this particular disk and removed special file for said disk prior to unpresenting this virtual disk.

When I do an ioscan -fnC disk on superdome it still considers this disk to be CLAIMED, how is this possible and can i remove it fully without bouncing the server?

Thanks for any assistance

lvreduce /dev/vg01 /dev/dsk/c1t1d0

for each disk.

The disk will continue to be listed as claimed as long as it is powred up and in the system.

Have done lvreduce/lvremove on all logical volumes and vgreduce/vgremove of volume group associated to this disk then rmsf on hardware path before unpresenting disk from the EVA side. It is not associated to this server from the EVA side yet it is still seen and claimed from the server side

Fiona,
is Secure Path installed on the Server? In recent versions you are supposed to remove the entry here first, before unpresenting the LUN on the storage array.
See the 'spmgr delete' command.

Hi Fiona,

It's not possible to remove it from ioscan output until you reboot the server. However, if you unassigned the LUN on EVA, you should see "NO_HW" associated with this disk after an 'ioscan -f'. That will go away once the server is bounced.

Thanks everybody who responded, required deletion from secure path.
