I'm running ESXi 4.1 U2. I've installed all of the latest firmware updates (Firmware DVD 9.30 plus the Service Pack disk from September 2011). When I "F8" into the controller setup at boot, I don't see any options to verify/adjust the cache settings, so is there another way to do this?

Attach this to the connector on the cache and when the battery charges (may be 30mins to 2 hrs) then all will be fine. If you are going to turn on Physical Drive Write Cache State make sure you have the server running off a UPS otherwise you may lose data on a unscheduled power outage. I recommend that all servers should be on a suitable sized UPS with the monitoring/remote shutdown software installed. It amazes me how many servers I see attached to UPS with no monitoring/remote shutdown software installed. o.O Hi gabrielpc1190,

Is it also possible to get the Cluster from this VM Host in the same skript? So that i have the rows: VMHostName, ClusterName, OverallStatus, CPU Usage, Memory Usage And it would be also great if i have a row with Host count. Hi,

Is a piece of s****. Customer has TWO licenses, and from month of using this product in production was HB working normally week i think. Everything was fine, until we try to patch operating system (MS Update). We use official KB (http://kb.vmware.com/kb/1010803) but of course this doesnt work and after that starts our problems. Now we are solving these with support third week and im crazy about it..... good luck Guys
