Cant create a new Volume Group

[martin clarke_1]

When I try to create a new volume group for a new disk pack SAM hangs and I had to kill it.
After some help from the guys on this forum I found that /dev/lvmtab has already got an entry for the physical device under vg02 but sam doesnt seem to detect any volume groups apart from vg00. Originally there were three volume groups VG00,01 an 02. I removed 01 and 02 which pointed to an old small disk pack.
I notice that the /dev.lvmtab file is read only.
How do I remove the vg02 entry.

Martin,

mv /etc/lvmtab /etc/lvmtab.old
vgscan -a

This will scan the system for existing vg's and re-create the lvmtab with what it finds.

(not sure what /dev/lvmtab is??)

Probably just a typo on my part

Hi,

just mv the lvmtab file to lvmtab.sav and then submit a "vgscan -av" command which will create a new lvmtab file with actual entries

Recreate lvmtab as mentioned. and check if still SAM hangs.

After recreating your lvmtab with vgscan as noted in above posts, create the vg from the command line:

mkdir /dev/vg02
mknod /dev/vg02/group group c 64 0x020000

vgcreate -s 8 -p 128 /dev/vg02 /dev/dsk/cXtXdX /dev/dsk/cXtXdX

where cXtXdX is/are the devices for the disks you want to add to this vg.

if vg02 is stil a volume group first do a vgexport on vg02. so it is removed from the system
