adding node to a 1 node sql cluster...'upgrading' from eval version
Posted on 2011-09-08
What I had:
A two node sql2008r2 cluster on server2008eval version. Eval versions are expired so both nodes reboot every hour or so. Cluster resource allocation not with standing.
xxxsql1 and xxxsql2 both nodes in xxxdbcl. Each machine is an MPIO enabled, dl580g5, with 24procs (4 seen by OS, 24 listed in devices, and bios, multicore's suspected), and 72gb of mem.
Anyway, I have evicted xxxsql1 from the node, and rebuilt the machine with a fresh OS install, 100 plus updates and patches, including sp1 and now have a fully validated 2008r2sp1dc build. It's imaged (i.e. backed up). It is now joined to the domain as xxxsql3, and with powerpath drivers installed is seeing the SAN disks. They are all offline and appear unconfigured.
What are the steps from here? Do I add the node to the cluster? Use the SQL install to add a sql cluster node? Configure the storage?
I can validate the configuration with a warning about the OS version and patch levels, which appears to be a prerequisite for success. Is this true?
Will my plan of adding a node with a valid OS evicting the eval node, rebuilding it with a valid OS and then adding it as new node to the old cluster work?
Appreciate any experience or tips on this process.
