SG 11.18 binary files on HPUX v2 and HPUXv3

[njia_1]

Hi there

I have a 7 nodes rx7640 cluster running HPUX v2 and SG 11.18.

We need to upgrade OS to HPUX v3 on all nodes, SG still 11.18

I have rebuilt standby node and installed SG 11.18 for HPUX v3 and I just rcp -rp /etc/cmcluster from one of the node still running hpux v2 to standby.

Looks like it is working fine, standby node joined cluster without any problems. application fail over is still disabled untill the primary node is upgraded to hpux v3 as well.

other things I tried.
I manually deleted /etc/cmcluster/cmclconfig on one node and that does not affect anything unless I halt the node then that node won't be able to join the cluster. If I copy /etc/cmcluster/cmclconfig back then the node joins cluster without any problems.

Here comes my question,
any problems with just copying cluster binary files from one node to another ? If I create Ignite backup tape from standby node, can I use it to rebuild all other nodes ?

To me, looks like it is OK but there may be something that I don't know.

thanks
Nan

Hi nija,

The size of cmclconfig is the same on all nodes in a cluster, but I would stick to the official way and do a "cmapplyconf" to compile the ascii conf file to a binary and distribute it among the nodes. Be aware that during cmapplyconf the quorum device/server or the lock disk should be reachable.

Regards,
Viktor

PS: for backup the ascii format of the config would be a much better selection ;)
