Single Node Cluster

[cheng]

Hello Folks,

Actually, I have a MC/SG with 2 node cluster. My MC/SG Version is A.11.14 with HPUX 11i.
My Problem is if I want to bootup node1 and halt node2. My cluster it can not boot up to single cluster, until my node2 is up then the 2-node cluster it can work. So how can I fix it.
I have some information in the attachment, if you want it please look at this, thanks !!

To start a SG cluster you need to run the command "cmruncl" or if you want to start the cluster only on a subset of nodes, you need "cmruncl -n node1 -n .." .

The cluster will not start if only a subset of nodes run the "cmrunnode" command. Only if all nodes belonging to the cluster run cmrunnode at the same time, the cluster will successfully start.

The startup script /sbin/init.d/cmcluster executed during boot executes a cmrunnode command, but not cmruncl. This means that all cluster nodes belonging to the cluster need to execute cmrunnode at the same time to get the cluster started.

I suppose that this is the "problem" at your site. One node is down and one node boots and executes cmrunnode. Since the other node is missing, the cluster will not start and give up after expiration of AUTO_START_TIMEOUT (default=10 minutes) as specified in the cluster ascii file.
