HI
I am having a strange problem and was wonderring if anyone else has seen it or has any suggestions.
I have several servers attached to a CX300 with flare 26.
All servers are running ESX 3.5 with ALL patches. There is also a VC server running 2.5
At moment we have all only one server running. It is connected to the CX using 2 qlogic cards. THe CX is configured to give failover mode 1 even though its flare 26 and could potentially use failover mode 4. But I know Vmware do not recommend failover mode4 yet.
Problem we have is we are able to see the luns but when we try to create a VMFS datastore it nearly always fails. We created 2 datstores of about 15. THe datastores are all less than 500GB.
If we go into console we can see it creates a vmfs partition on the luns but it does not format or give it a valid label it never appears as a datastore and is not listed under /vmfs/volumes. To be able to use the lun again I have had to manually edit the file table and delete the partition created.
The CX appears to be fine we do not see any errors on itr or on the connected switches.
All the servers are fresh installs, no upgrades all installs are done using tested media (iso images checked by md5sums) all hardware is on supported hw lists.
any suggestions? any ideas?
