vSphere U1, 1 down, 1 to go.

Good news first - in my previous blog post I had mentioned that there was a serious bug with updating to ESX 4 U1 and HP SIM agents. This has been resolved, U1 has been re-released and people should not have this issue any more (I have not tested this myself). That KB article has been updated and is available here.

The bad news is that there is now a bug with U1 and vCenter if it manages ESXi hosts.

It does not seem nearly as drastic as the previous issue I blogged about, but you should be aware of it. For now, it seems that you can avoid running into it by not adding, removing and then readding an ESXi host to vCenter.

Stay tuned for my next post (possibly a series?) about backups.
