Intercomsolutions,   You actually can use OMSA on ESXi, now you won't be able to accurately monitor the VM's with it, but you can monitor the host. If you follow this link, it will take you to a posting I did previously, which includes a walk through on installing and running OMSA in ESXi. Let me know how it goes.
Hi, we have a Dell PowerEdge R710 with iDRAC 6 Enterprise. When I open the iDRAC web interface, there is no information or status of the Perc H310 RAID controller. I can't see physical disks, no virtual disk, I've searched in every place and is missing every reference to the storage. I've used other iDRAC cards and the RAID controller is always present. iDRAC just updated to last firmware, server already restarted. Any Idea? Claudio Basso
