why Cur PV is larger than Act PV

Hi

Once I replaced a disk in a HP-Ux server running service guard cluster, vgdisplay is showing as below.

vgdisplay -v /dev/vgshare >>

VG Status available, exclusive
Max LV 255
Cur LV 1
Open LV 1
Max PV 28
Cur PV 9
Act PV 8
Max PE per PV 10000
VGDA 16
PE Size (Mbytes) 8
Total PE 52356
Alloc PE 52356
Free PE 0
Total PVG 0
Total Spare PVs 0

PV Name /dev/dsk/c6t3d0

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?

How did you replace the disk?

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

There is at least the "vgcfgrestore ..." step missing.

Which disk did you replace?

Please run a "pvdisplay" on it.

Hope this helps!
