Hi JRM,

You may need to make the VG cluster-unaware now that you've removed MC/SG:

vgchange -c n vg05

Rgds,

hi Jeff.

I do the command vgchange -c n vg05 and the system reply.

sdmadr3# vgchange -c n vg05
vgchange: Warning: Couldn't attach to the volume group physical volume "/dev/dsk
/c5t8d0":
The path of the physical volume refers to a device that does not
exist, or is not configured into the kernel.
vgchange: Could not attach to volume group "vg05" all of
its physical volumes.
vgchange: Warning: couldn't query physical volume "/dev/dsk/c5t8d0":
The specified path does not correspond to physical volume attached to
this volume group
vgchange: Warning: couldn't query all of the physical volumes.


Thank you for help me.

JRM.

Hi JRM

If you want to remove the whole volume group (vg05) you can use

# vgexport vg05
