Device Busy message from vgcreate command

[ColoUser]

Hi All,

I'm trying to create a volume group using the vgcreate command. I get an error message saying the device is busy. I did fuser which didn't return any processes, etc. How do I determine what is attached to this device?? I've tried lssf, ioscan, but no additional info that is useful.

The server is hp 9000/800/N4000-55, OS 11.00.

#vgcreate /dev/vg03 /dev/dsk/c3t0d2
vgcreate: Couldn't open physical volume "/dev/dsk/c3t0d2":
Device busy

# fuser -u /dev/dsk/c3t0d2
/dev/dsk/c3t0d2:

I'm a novice using LVM commands so any help would be greatly appreciated.
Linda

Did you check if your device is not use in an other vg ?
# strings /etc/lvmtab | grep /dev/dsk/c3t0d2

Before adding the pv, you have to declare it using pvcreate :
# pvcreate /dev/rdsk/c3t0d2

First on all, use ioscan to make sure the /dev/dsk/c3t0d2 is there ?
Then do a insf -e to make sure the drivers are loaded properly.
From the device name looks like you are using a disk array, make sure that there is no secondary/alternate path point to the same disk
strings /etc/lvmtab is a good way to find out if the device use in another VG
Then do a pvcreate -f /dev/rdsk/c3t0d2
