Patched various DL380 G4 servers with 32 bit SLES9 last night. Yes, I know these machines could run 64bit, but SLES9 64bit was not available to us when we set them up. Patching went smoothly – until the second to last server. It hung on reboot. I cancelled the patch of the last server when we couldn’t recover immediately. That last server? A highly critical server, where an outage would have actually cost money. The system is being moved to a cluster in 1-2 weeks. I guess murphy was sleeping tonight.

The cause is under investigation.
