OES11 SP1 at warp speed!

Another successful upgrade to OES11 SP1 was completed this week!

This one was slightly different from normal because of the very tight schedule required.  Early morning starts and late finishes enabled us to upgrade four standalone servers from OES2 SP3 (SLES10 SP3) to OES11 SP1 (SLES11 SP2), add a node to each of two clusters, and then perform a rolling upgrade of the existing nodes with no user downtime at all!

As an aside, the upgrade to OES11 SP1 significantly improved the AFP performance and simplified its configuration by enabling the new LDAP subtree search feature, reducing the number of LDAP contexts from over 30 to just one!
