when to run cmmakepkg during patch installation

kumardev — Tue, 05 May 2009 14:16:51 GMT

Hi ,
I am about to install a service guard patch in one of my MCSG, which mentions that there is a need to create the control script(cmmakepkg), can you please tell me as to when to do that , the steps that I have prepared are as:
1)Move the pkg from the primary node to the HA node.
2)halt the Service guard on the primary node node.
3)patch the primary node, reboot it if required.
4) Start the service guard on teh primary server.
5)failback the pkg to the primary node.

Can can you please tell me as to when to run the cmmakepkg in the above mention steps?

Regards
Kumardev

Shalom,

You can run cmmakepkg before or after step 2.

I would try for before.

Thanks for the reply,

But in the HP docs it says that we have to recreate the control script after the installation of the patch, but befor or after step 2 we still havnt installed the patches..:-(

appreciate your help on this.

Here's what I been using for years and taken from the MC/SG II class.

a) all your LVM work is done and you've vgexported and ftp'd from the pri to the failover.

mkdir /etc/cmcluster/package_name
cd /etc/cmcluster/package_name
cmmakepkg -p package_name.conf (* note conf ext *)

vi package_name.conf
fill in data fields like:
PACKAGE_NAME
NODE_NAME
RUN_SCRIPT ${PWD}package_name.cntl (* see below *)
HALT_SCRIPT ${PWD}package_name.cntl (* see below *)

cmmakepkg -s package_name.cntl (* note ext. *)
vi /etc/cmcluster/package_name.cntl
fill in data fields like
VG[0]
LV[0]
IP[0]
etc.

Addin customer defined start commands like
oracle.sh start

Addin customer defined stop commands like
oracle.sh stop

chcheckconf -P package_name.conf
cmapplyconf -P package_name.conf
vgchange -c y vg??
vgchange -a n vg??
cmmodpkg -e package_name
cmrunpkg -n node package_name
cmviewcl

NOTE: This is 80% of it. Better to take the class, or, draft everything out on paper before applying in a test environment.

Thks for the replies, just one more thing

1)if the package(1) is running on the primary node(A) can i run the cmmakepkg for pkg 1 on the HA(node B) which is in the same cluster, if not what impact it can cause on the system.
2) if the package is running on the primary node(A) can i run the cmmakepkg on the HA(node B) which is in the same cluster, if not what impact it can cause on the system.

the only reason why I am asking is to know the best time to recreate the control script by using cmmakepkg after patch installation

Hi Kumardev,

>>>1)if the package(1) is running on the primary node(A) can i run the cmmakepkg for pkg 1 on the HA(node B) which is in the same cluster, if not what impact it can cause on the system.<<<

cmmakepkg will just create the template of pkg config file or pkg control script. Once you made all the changes on both config file and control script, you need to halt the package and apply configuration using cmcheckconf and cmapplyconf commands.
