All the NFS datastore are unmounted
We have a HA & DRS cluster in our virtual environment. The ESX version is 3.5 and the virtual center version is 2.5.
The storage for all the ESX hosts in this cluster are provided from NetApp storage. The Luns are assigned to all ESX hosts as NFS. So the storage for the ESX is a NFS storage.
All of a sudden in one of the ESX host all the LUNs are shown in the virtual center as inactive. In other ESX hosts they are working fine.
I have checked the configuration of this ESX host with others in the cluster, every thing seems to be fine. Checked with the storage team and they said every thing is fine from their end.
I have enclosed the Logs, kindly refer.
I need to find a solution for this. Thanks

check the Host server can still contact the NFS server?
ASKER
Yes the Host can contact the NFS server. IN addition to that we have the nfs server names listed in /etc/hosts file as well
I could ping the NFS server but vmkping fails.
Moreover, the NFS shares are configured through VMHBA cards and not through iscsi adaptors

Ok. But I am using HBA cards and I need understand here what is the relationship with VMkernal portgroup
We have the VMkernal portgroup for vmotion and not for the iscsi connectivity
We have the VMkernal portgroup for vmotion and not for the iscsi connectivity
VMKernel is a special portgroup which carries iSCSI and NFS traffic.
ASKER
Ok. You mean to say If I recreate the vmkernal portgroup the issue may fix right
if you have removed it, or you do not have one, YES!

I have the vmkernal portgroup
I changed the NIC Teaming settings , now I could see some of the volumes are mounted

But still some volumes seems to be unmounted
can you vmkping the server.
check the IP address or DNS references, you may need to re-create the connection and datastore names.

Enclosed is the output when I ran the command.
ls -l /vmfs/volumes
I just need to understand why still some datastores are inactvie, while all the NFS volumes are mounted:

ocassionally, nfs mounts do not mount again, incorrect permissions, cannot find the NFS server.
dismount, and just re-create the connection, if the mount is not successful it will report the error message, and reason why.

I am unable to do a vmkping for the unmounted NFS
