Hi

You shall according to the Error that you are getting will need the following things to do.

1) do an ioscan on the 2nd node and make sure that you are able to see the disks in there and they are showing as claimed that is the disks are accessiblt to the 2nd nide also.

2) export the existing VG on 2nd node using

vgexport /dev/cs03p1l1
mkdir /dev/cs03p1l1
mknod /dev/cs03p1l1/group c 64 0xAA0000
make sure that the Minor no of the group file is unique on node 2 and also the same as that on the node1.
vgimport -v -s -m /tmp/cs03p1l1.map /dev/cs03p1l1

make sure that when you are importing the VG on the 2nd node, you are sure that the Applications/Packages that might be running on 2nd node and accessing that VG arein a down state.

Also make sure that afetr this cahnge in teh VG configuration you test the package by running on both the nodes so that you are sure that in event of the failover of the package, the start and run of the package is smooth on the other node.

hi yogesh

You need also to update you package configuration to insert the new LV's created.

Best regards.
