vg00 physical volume is my cdrom

kouadio — Mon, 15 Mar 2010 13:46:55 GMT

Hi expert,
I have install my system with a cdrom.
Now when I run vgdisplay -v vg00
I see that the physical volume of vg00 is /dev/disk/disk5_p2; and when I run ioscan -m dsf to map device file name I see that /dev/disk/disk5 correspond to c0t0d0. The problem is that when I run diskinfo c0t0d0 I see that this device is the cdrom. How can do to correct this problem

Hi:

> I see that the physical volume of vg00 is /dev/disk/disk5_p2; and when I run ioscan -m dsf to map device file name I see that /dev/disk/disk5 correspond to c0t0d0.

So what's wrong with that? On an 11.31 server of mine:

# ioscan -kfNnC disk
...
disk 5 64000/0xfa00/0x3 esdisk CLAIMED DEVICE TEAC DVD-ROM DW-224EV
/dev/disk/disk5 /dev/rdisk/disk5

# ioscan -m dsf
...
/dev/rdisk/disk5 /dev/rdsk/c3t0d0

Regards!

Hi (again):

And, once again, what do you think is wrong here? What problem are you attempting to solve?

Can you please post (attaching would be better) your full 'vgdisplay -v vg00' and the full 'ioscan' output.

hi,
the problem is that for me my physical volume in my vg00 volume group must be a SCSI disk not a CDROM, and when I try to use vgextend on vg00 I get this error:
Couldn't open physical volume "/dev/rdisk/disk5_p2"
Verification of unique LVM idon each diskin the volume group vg00 failed

You can also show vgdisplay -v to find out whether those scsi disks have been put into Volume Group.

Post the exact command and command arguments you used, please. Guessing what your configuration looks like and/or guessing what arguments to commands you have supplied gets us no where fast.
