we have a RAID 10 datastore (4x SAS) on an IBM x3650M2 server but our VMWare ESX 4.xx server does not see this datastore.

Does anybody knows whats wrong there?

Is the array controller on the HCL? The only SAS array I see supported from IBM for esx 4 is model 1820N00. If it's built in servraid make sure its one of these Also note:

"SAS 2.0 controllers are supported only with VMware ESX/ESXi 4.0u1 and newer releases"

It´s a ServeRaid M5014 SAS/SATA Controller. The ESX regognizes a RAID 5 but not RAID 10.

I can´t find ESX4.0U1. Where is it downloadable?

Thank you for the link. Why isn´t the update shown in the vSphere Host Update Utility? – Tom Feb 10 '10 at 14:06
I don´t know why but now I see the disk in the LUN configuration. – Tom Feb 10 '10 at 14:07
Don't know, I use VCUM not the HUU. – Chopper3 Feb 10 '10 at 14:20
