Adding VG on MCSG Metro cluster

[manoj_pu]

Hello All,

We have hp production systems with 11i and MC ServiceGuard - A.11.15.00.

We are planning to include one new volume group and file systems in the existing Package.

I would be grateful if anybody could clarify/respond my below queries.

1. Is it necessary to update on cluster configuration?
2. If answer is no, to update package configuration is it necessary to update package configuration with cmapplyconf.

Kind Regards,
Manoj

Hello All,

Sorry I missed the important part in my query,
Can I do this exercise (adding new VG) while cluster and package is running?

Kind Regards,
Manoj

Hi, yes you can add the vg and edit the control files accordingly.

Make sure to do it on all nodes or sync the controlfiles.

Hi Rariasn,

Do you mean following would work please clarify.

1. Make VG cluster aware manually
2. Include VG in pkg control file to activate exclusive mode while in pkg startup
3. Include FS in pkg control file to mount fs while pkg startup

Manoj

Hi,

Primary node:

- create newvg
- vgchange -c y vgnew
- vgchange -a e vgnew
- vgdisplay vgnew
- create newfs
- vgexport -p -m /tmp/vgnew.map vgnew
- copy vgnew.map to secondary node
- vgchange -a n vgnew

Secondary node:

- vgimport -p vgnew.map vgnew ...
- vgchange -a e vgnew
- vgdisplay vgnew
- vgchange -a n vgnew

Primary node:

- vgchange -a e vgnew

Modifify package "control script" for add "vgnew" and newfs.

Copy "control script" to secondary node.

Regards,

Rariasn.

Hi Rariasn,

Thanks for your response.

Your response did answer my questions.

However I have another question coming in mind.

What would be the necessity of having all volume group entries in cluster configuration binary file? Could you please tell me?

Kind regards
Manoj
