Need to remove a package from arunning cluster

[Sreer]

Hello Gurus,

I need to remove a cluster package from a running cluster.

what I planned is as below:

say pkg is mypkg

# cmhaltpkg mypkg
# cmdeleteconf -p mypkg

rm -r /etc/cmcluster/mypkg

any more steps remaining?

My question is:

Do I need to delete/destroy Vgs and related LVS/FS ?

[Hope while halting the pkg its self these export might have happened?]

If you can correct my steps that willbe great !!

THANKS FOR YOUR REPLY.

Even though I have not touched a sg cluster in last 3 years and then some, steps seems to be okay. Although, you are not necessarily obligated to remove /etc/cmcluster/mypkg files/directories. Them staying behind, just in case you need an unexpected recovery need, would be to your advantage.

And yes, cmhaltpkg command would take the lv's and vg's of the service group, off-line. Destroying the VGs and LVs are upto you but if I were you, I would not jump the gun for a reasonable period of time, like 3-6 months. I believe, if no one is looking for that application after 3-6months, it is safe that you are free and clear of it. Then you can remove all traces of the package. This is just my personal opinion.

Hi,
Your plan is ok. If you don't need the file systems/logical volumes or volume group anymore then you can destroy the volume group.

Hello Sree !!

If you don`t needs those VG /LV stiff ..you may export the VG itself all the device files will be exported for VGs & LVM , you may keep a map file for your reference if needed.

Hi Gurus,

Thanks much for your help.

One querry still remaining.

Do I need to do create ASCII file of cluster and reomeve the PKG entry from it and to apply using cmapplyconf ?

or just cmdeleteconf is enough?

I believe the package name is never mentioned in cluster.conf file it`s mentioned only in the
package control file , no changes to cluster conf file in this regard !!

Hi,
cmdeleteconf is enough...

Hi Sree:

# vgchange -c n vgname

# cmdeleteconf

and cmgetconf to verify
