Although no of availble PV is 8, why it shows as below?
Cur PV 9
Act PV 8
Is this a real issue in the server?

Re: why Cur PV is larger than Act PV
Wrong procedures may cause you have the old AND the new disk in your configuration.
Hope this helps!

Re: why Cur PV is larger than Act PV
Hi
I used following procedure to replace disk.
# lvreduce -m 0 -A n /dev/vgshare/lvshare /dev/dsk/c5t3d0
Then physically replaced the disk.
# Ioscan -fnc disk
#vgchange -a y /dev/vgshare
#lvextend -m 1 /dev/vgshare/lvshare /dev/dsk/c5t3d0
That's it.
Is my procedure incorrect ?

Re: why Cur PV is larger than Act PV
Which disk did you replace?
Please run a "pvdisplay" on it.
Hope this helps!

Torsten.
