Test Volume Group Activation On Each Node

This should be done for each volume group, vgws and vgclog, to verify volume group activation on

each server. The steps shown here are for vgws.

1. On the first server (for example, adam)

a. Activate volume group:

b. Write test file to volume group:

echo “Written by” `hostname` “on” `date` > /ws/test

cat /ws/test

NOTE: If you try to activate vgws on the other server, it should fail. For example:

vgchange -a y vgws

0 logical volume(s) in volume group "vgws" now active
