unused disk?

[GraceO]

I was trying to create a new volume group using an 'unused disk' disk via SAM. [SAM shows the disk as unused.] I got an error saying my disk was already recorded in the lvmtab file. Looking at lvmtab, I see the disk (/dev/dsk/c8t10d0) associated with a volume group (/dev/disk5_36). When I try to view the volume group, I found it to be inactive.

When I tried to activate the volume group, I get an error, "Quorum not present, or some physical volume(s) are missing."

lvmtab looks like:
/dev/vg00
/dev/dsk/c1t2d0
/dev/disk3_36
/dev/dsk/c8t8d0
/dev/disk4_36
/dev/dsk/c8t9d0
/dev/disk5_36
/dev/dsk/c8t10d0
/dev/disk6_36
/dev/dsk/c5t8d0
/dev/dsk/c6t8d0
/dev/disk7_36
/dev/dsk/c5t9d0
/dev/disk2_18
/dev/dsk/c2t2d0
/dev/disk10_36
/dev/dsk/c6t9d0
/dev/disk11_36
/dev/dsk/c6t10d0
/dev/disk14_36
/dev/dsk/c7t10d0
/dev/dsk/c7t9d0
/dev/disk0900110
/dev/dsk/c6t11d0
/dev/disk01200110
/dev/dsk/c7t11d0
/dev/dsk/c7t8d0
/dev/disk0100110
/dev/dsk/c8t11d0
/dev/disk0800110
/dev/dsk/c5t11d0
/dev/disk0800100
/dev/dsk/c5t10d0

partial ioscan looks like:

Is my disk really unused? And how can I clear up lvmtab so that I can use the disk?

Any help would be greatly appreciated...

use vgexport to clear the vg entry from lvmtab since vg is inactive already.

Then you can create new vg on the disk after doing vgexport.

Forgot to mention the command:

vgexport /dev/disk5_36

That fixed it! Thanks!
