Sujeet,

Suspect you may have exceeded the Max PV/VG value.
Can you post the output of vgdisplay -v /dev/vg01.

Shalom sujeet,

It is likely that you are going to have to back up the data and rebuild this Volume group.

First test that the disk is properly connected and configured with one of the ideas below:

ioscan -fnCdisk
mstm/cstm/xstm # test the disk.

Check with the san admin that the LUN is properly assigned if relavent.

The max PV limit can be set only at the vg creation with the vgcreate command.
You need to backup your data and rebuild the VG (and LV) with the -p max_pv option then restore your data.

Look at the output you posted:

Max PV 16
Cur PV 16
Act PV 16


current value == maximum value.

You can't change this, it's only possible while creating the volume group.
