Adding hard disk

[Vijaya kumar_1]

Hi all,

I have a hard disk and configured with LVM. I removed from one controller and put in another controller for a controller failure.

Sam just now created device files like /dev/dsk/c0t5d0.

Can anybody tell me how to add a hard disk which has data previously in "vg05" with only one "lvol1"...

The problem is the hard disk contains data and should be carefully restored.

Thanks in advance
Vijay

Hi, Vijay

#vgreduce -f /dev/vg05 (since vg05 has been eliminated)
#vgscan -v
#mkdir /dev/vg05
#cd /dev/vg05
#mknod group c 64 0x050000
#vgimport -v /dev/vg05 /dev/dsk/c0t5d0 (new path for hard disk)
#vgchange -a y /dev/vg05
# mount /dev/vg05/lvol1 /

I am getting this error

#vgreduce -f /dev/vg05
vgreduce: The volume group "/dev/vg05" is not active. Only an active
volume group can be extended.


Thanks

Vijay

Hi, Vijay

could you use vgremove /dev/vg05 which remove vg05 definitions from root disk

[Vijaya kumar_1]

I did a vgexport vg05

that works fine.

Thanks for the fantastic help.

Vgimport would be the best way to add it back in, as well.
