Hello
we have a virtualized environment with two ESX 4.1.0 (988178) hosts, and an external storage (SAS-based IBM DS3512).
On the external storage we have a VMFS (version 3.46, 4MB block size) of 1.95 TB.
We have added a 600GB disk to the DS3512 in order to expand the LUN up to 2.79 TB roughly.. The LUN expansion, at storage level, has gone ok. If we check the Storage Adapter properties for the SAS adapter connecting to the LUN, we see it detects the new size (2.79 TB LUN).
From the vCenter, we went to one of the ESX 4.0 hosts, Storage view, right clicked on the storage and selected Properties. There there's an active button for "Increase...". If we click on that we get an error message saying --
Call "HostDatastoreSystem.QueryAvailableDisksForVmfs" for object "datasotreSystem-28" in vCenter Server "SRVVC" failed. --.
After this we get an empty extension window so we cannot proceed...
I guess we are missing something and I am asking for some advice. We have expanded VMFS before but they were below the 2TB limit, and it was pretty easy.
How can we make so that we can expand the VMFS to the maximum LUN size (2.79 TB).
Any suggestions?
Ciao and thanks in advance
Alessandro
