Problem modifiying a package withe a cluster node down

Hi,

I have a 3 node cluster with hp-ux 11.11 and sg 11.15, one of the nodes(node1) in the cluster is down, and deleted for good, never comming back.

The problem I have is pkg A , has configured as failover nodes node 1 and node2, now that node1 is gone, I need to configure node2 and node3 as failover packages in pkgA.

The problem is with node1 down i can't modify hte package, i get:

> cmcheckconf -v -P pkgA

Checking existing configuration ... Done
Gathering configuration information ... Done
Parsing package file: pkgA.conf.
Package bqmp already exists. It will be modified.
Error: Run script /etc/cmcluster/pkgB/pkgB.cntl for package pkgB
does not exist on node node1.
Error: Run script /etc/cmcluster/pkgC/pkgC.cntl for package pkgC
does not exist on node centauro2.
Maximum configured packages parameter is 20.
Configuring 5 package(s).
15 package(s) can be added to this cluster.
cmcheckconf : Unable to verify package.

I also can't delete the pkg and recreate ir again because node1 is down:

cmdeleteconf -v -f -p pkga
cmdeleteconf : Unable to delete the packages.
Error: Cannot connect to configuration daemon (cmclconfd) on node node1
Error: A temporary configuration file ($SGCONF/cmclconfig.tmp) cannot be written to disk on one or more nodes: No such file or directory
Error: Cannot connect to configuration daemon (cmclconfd) on node node1
Error: A temporary configuration file ($SGCONF/cmclconfig.tmp) cannot be removed from one or more nodes: No such file or directory
Error: Unable to apply the configuration change: No such file or directory
. Check the syslog file(s) for additional information.

So i can't delete node1 from the cluster config, because it has packages with node1 configured as a failover node...

cmcheckconf -v -k -C cmclconf.ascii

Checking cluster file: cmclconf.ascii

15 package(s) can be added to this cluster.
cmcheckconf : Unable to verify cluster file: cmclconf.ascii

I have no way of restoring node1, is there I way of getting this working without stoping the cluster??.

If not i will have to stop the cluster, cmdelete everything and reconfigure it again

I finally found out the way to do it, you have to run all the modifications at the sametime.

In the same command I delete node1 from the cluster, and also modify the packages removing node1 as a failover node in all the packages, and also adding node3 as a new failover node.

Example:

#cmapplyconf -v -k -C cluster.ascii -p pkg1/pkg1.conf -p pkg2/pkg2.conf -p pkg3/pkg3.conf
