Trying to Create a volume Group

[Frank Salinas]

I get a device busy error when trying to create a new volume group on newly allocated external storage. I have done pvcreates on my new didks and mkdir of /dev/vg?? and mknod /dev/vg??/group. I nneded to create two volume groups the first woked just fine. And the seconf I get device busy. They are going to completly different disks. Below are the actual commands and results. Any suggestions would be greatly appreciated.


root@dvm-da-0:vgcreate -s 128 -p 255 /dev/vgsapmi /dev/dsk/c4t9d5 /dev/dsk/crt9d5 /dev/dsk/c4t9d6 /dev/dsk/c5t9d6

Increased the number of physical extents per physical volume to 1152.
Volume group "/dev/vgsapmi" has been successfully created.
Volume Group configuration for /dev/vgsapmi has been saved in /etc/lvmconf/vgsapmi.conf

root@dvm-da-0:vgcreate -s 128 -p 255 /dev/vgsapxi /dev/dsk/c7t9d5 /dev/dsk/c8t9d6 /dev/dsk/c7t9d6 /dev/dsk/c8t9d5

Increased the number of physical extents per physical volume to 1152.
vgcreate: Volume group "/dev/vgsapxi" could not be created:
Device busy

Frank,

Can you paste the output of # ls -l /dev/*/group ,

And also check the disks " /dev/dsk/c7t9d5 /dev/dsk/c8t9d6 /dev/dsk/c7t9d6 /dev/dsk/c8t9d5 " are given correctly,

Cheers,
Raj.

Here is the ls -l


root@dvm-da-0:/root >ls -l /dev/*/group
crw-r----- 1 root sys 64 0x000000 Sep 28 09:29 /dev/vg00/group
crw-r--r-- 1 root sys 64 0x020000 Dec 6 14:44 /dev/vgsapmi/group
crw-r--r-- 1 root sys 64 0x010000 Dec 6 14:44 /dev/vgsapxi/group
root@dvm-da-0:/root >

[Sandman!]

Could you attach the output of the following commands:

# ioscan -funC disk
# ioscan -funC ext_bus

Here are the ioscans.

[John Guster]

please post vgdisplay -v vgsapmi

[Coolmar]

Did you use pvcreate -f ?

Hi,

make sure you're not trying to create new VGs using the alternate pathes of previous used LUNs. SAM (or a hitachi related tool) can probably tell you more.
