Shalom,

Your volume group configuration is not consistent between the two nodes.

When building a cluster, volume group and disk information must be consistent on both nodes with regards to the shared volume groups.

You vgexport with the -p (preview) to a file, move the file to the second node to insure consistency.

This step has not been done correctly.

Also note, vg00 can not be part of the shared volume group. vg00 is the volume group each node boots off of. You can not share logical volumes or disks that are part of vg00.

Hi Fizan,

The error is
******
Volume group /dev/vgpkg1 is configured differently on node rx26-151 than on node rx26-152
Volume group /dev/vgpkg1 is configured differently on node rx26-152 than on node rx26-151

*******

Simply follow as:-

1. Create a VG on one node.
2. vgexport that VG in preview mode to create a map file.
3. rcp that map file to other node.
4. create VG with same name and minor number on other node.
5. vgimport that VG with the map file copied.

Now try to run cmcheckconf command.

fizan,
Have you tried creating the package ascii file and control file: if not you have to run cmmakepkg , and then to try cmcheckconf & cmapplyconf subsequently:

# cmmakepkg -v -p pkg1.conf

# cmmakepkg -v -s pkg1.cntl

#cd /etc/cmcluster/pkg1/
# ls -l #files must be there.

Then modify the pkg1.conf and pkg1.cntl file as per the need & configuration , include vg,lv,fs details on pkg1.cntl.
Copy the files in FO node ,same location.

And then run:

# cmcheckconf -v -P pkg1.conf #Remember Upper case "P" .

Cheers,

Raj.

Fizan,

Points:

1. As SEP says,the root VG for any Server- vg00 should not be shared.
The VG created on the SAN are shared in HP SG.

So as a start check the VGs on your Cluster environment...

2. cmcheckconf -v -C /etc/cmcluster/cluster.conf -p pkg1.conf <---
it should -P pkg1.conf

Step-by-Step...

Let U know your progress...and where U get stuck...
Keep the SG Admin guide near you.

Assign points to all while u are at it :-)

You need to reimport the VG to secondary node and then rebuild the cluster.

first cretaed shared volume group executed the svg on both node n1 n2

then cmquerycl -v -C cluster.conf -n n1 -n n2

then cmcheckconf -v -C cluster.conf

then cmapplyconf -v -C cluster.conf

cmviewcl -v--- cluster up running ok. done.

pwd
/etc/cmcluster
mkdir pkg1
cmmakepkg -P pkg1.conf
cmmakepkg -P pkg1.cntl

chmod 755 pkg1.conf

cmcheckconf -v -C pkg1.conf

Hi Fizan,
Try the command like as follows and see what is happening

cd /etc/cmcluster/pkg1
cmcheckconf -v -P pkg1.conf
cmapplyconf -v -P pkg1.conf

Hi Fizan,
If you are using the full line "cmcheckconf -v -C /etc/cmcluster/cluster.conf -p pkg1.conf
" as a command I think that is the mistake

Please paste following command outputs

# ll /etc/cmcluster

# ll /etc/cmcluster/pkg1
