+1 from here as well. A vCenter reboot should not require a host reboot. If it did, that would (IMHO) be a huge problem in the design and purpose behind VMware. Talk to VMware. If your maintenance is not current, get current.
On a related note, YESTERDAY, one of our storage groups on our SAN ran out of space (fortunately I'm not in or over the group responsible for that anymore!), and thus took down a number of systems, all part of our core electronic medical record system, eClinicalWorks, all virtual... We were without that app for more than 6 hours, and are still dealing with database replication issues today as a result.... TGIF! Jonathan L.

Today, a SAN blows up and takes out half - our SharePoint server (heavily used), a Terminal Server , and an internal occasionally-used web server (Namescape rDirectory). Then somehow, when I was told to power down the other 4 VM's so our VMWare guy could reboot a vCenter server, 3 of the 4 remaining VM's decided to go AWOL (a combination of "missing" and "disconnected"). That took out my other two Terminal Servers and another lightly used internal web server. Did I mention I don't have the normal backups for these things because ...well...I'm an idiot and didn't confirm our backup guy installed backup software on these servers as I stood them up (process error on my part since I should confirm it's on there). None of these store data - they all talk to a backend SQL and the Terminal Servers are used to run apps that are slow if they run the same apps over VPN. SharePoint we got back quick because we do have a staging equivalent of it, so it was repoint to a config and content DB, DNS change, and done. I do have copious notes on how I built the others and can rebuild from scratch easily enough (I just finished the three TS boxes), but dude...six servers at once? The most frustrating part was discovering that the 4 systems that had been powered off could have been "migrated" before power off and there would have been no issue with them - the power down nuked 'em. Oh, and the lone surviving server - the PGP Universal Server that manages the encrypted machines. (Yes, the PGP machines will still boot w/out the server up, but still, I've been on this server 50% of my time over the last two weeks!).
