Error in vgcreate command

CA1005821 — Mon, 27 Oct 2003 04:56:44 GMT

Hi all,

I have an error in my vgcreate command. The error states:
====================================
vgcreate: Cannot open the control file "/dev/vg02/group":
No such device
====================================
What have caused this error? I have scaned using ioscan but it displays the the raid device.
====================================
disk 5 0/7/0/1.0.0.0 sdisk CLAIMED DEVICE I2O RAID5
/dev/dsk/c5t0d0 /dev/rdsk/c5t0d0
====================================

I have already done the pvcreate command, created the vg02 directory, and already executed the mknod command.

Thanks in advanced.

Karl

Hi Karl,

Could you check next command, to check the minor and mayor numbers.

# ls -ll /de/*/group

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

# vgcreate /dev/vg02 /dev/dsk/c5t0d0

Hope it helps,
Robert-Jan.

Thanks for your reply. The group file for vg02 is already existing. Here is the output of the command you gave me.

# ls -ll /dev/*/group
crw-r----- 1 root sys 64 0x000000 Oct 22 14:46 /dev/vg00/group
crw-r--r-- 1 root sys 64 0x010000 Oct 27 15:41 /dev/vg01/group
crw-r--r-- 1 root sys 64 0x020000 Oct 27 18:17 /dev/vg02/group

But still I have the same error when I execute the vgcreate command.

Best regards,

Karl

Hi Karl,

Please check the syntax of your command and order.
I am listing the command for info. Please use caution during use of these commands.

1. mkdir /dev/vg02
2. mknod /dev/vg02/group c 64 0x020000
3. pvcreate -f /dev/rdsk/disknumber
4. vgcreate /dev/vg02 /dev/dsk/disknumber

Hope this helps

Karl,

Could you check the permission of /dev/vg02

# ls -lad /dev/vg02
drwxr-xr-x 2 root root 1024 Oct 7 15:56 /dev/vg02

and the maxvgs kernel parameter.

# grep maxvgs /stand/system
maxvgs 80

Regards,
Robert-Jan.
