To split the package & use the disk as shared filesystem across 2 servers.

[HP-UX_Ali]

Dear all,

Kindly help to resolve the below issue.

i want to remove the below package from running cluster & use as a cfs filesystem. Pls provide the steps to deconfigure the below package & also how to know the disks associated with below package.

Note: this is Metro cluster & package has been halted in all nodes.


xx_xxx_db_dg down halted enabled no
xx_xxx_db_mp down halted enabled no
xx_xxx_arch_dg down halted enabled no
xx_xxx_arch_mp down halted enabled no
xx_xxx_RACDB down halted disabled no


Thanks to confirm

check /etc/cmcluster/cluster.ascii(there should be at least one on all those servers and see whether there were "VOLUME_GROUP" configured at it; check /etc/cmcluster//.cntl and find out which VG[*] configured below # VOLUME GROUPS, these VGs were configured in the cluster, hence the PVs belonged to those VGs were, as what you said, associated with those package.
as for "deconfigure" those packages, I have never tried, but you could tried cmapplyconf -C /etc/cmcluster/cluster.ascii to see what would happen, before backing up /etc/cmclconfig, as i recall, there is cmdeleteconf, check the manpages.

regards
stephen

Hello Stephen

Thanks for the reply, but i dont want to delete the package permanently , only to deconfigure and use the mount point temporary mount as cfs and again use the (package) mount point in cluster.
As it is metro cluster . i knew we have to split the pair (as it is continous access from XP12000).

if any one has steps to deconfigure and use the disk group & again put it back as it is before. Pls confirm....

just comment every line above # VOLUME RECOVERY in /etc/cmcluster//cntl to disable filesystem mounting when cluster startup. I think that would meet your need.
one thing I should add is that you just need to use those mount point and not try to reconfigure all those VGs that configured in packages?

Yes stephen,

I just want to use it temporarly (may be 1 Month) not to reconfigure. Later i want to active the above packges.

What i have in mind.
1. Split the pair b/w to site
2. halt the package
3. Import the disk-group
4. recover the volume (vxrecover or vxdg -g startvol
5.mount the file-system with CFS (cfsmount)

But as this production env, i want to be sure. Kindly confirm the above steps can be carried out.


Thanks
