Inserting Media from NFS Server Fails
Problem
The process of inserting media (CD or floppy images) from an NFS Server
fails.
Solution
Pinpoint the Managed Server system involved in the operation. (The error
message typically displays the name of the involved system.)
Make sure all Managed Server systems meet these requirements:
You properly configured the VMkernel.
The VMkernel is attached to a NIC that has connectivity to the NFS storage server.
The gateway of the VMkernel is set to the correct value for the network.
The NIC is up.
Conflicting NFS datastores cannot exist on the Managed Server system.
Conflicting datastores can arise either through the external creation of such
datastores or through internal processes within Lab Manager.
Typically, Lab Manager creates datastores with the LabManager
‐
NFS
‐
<ID>
naming format which points to all NFS storage servers enabled on the Lab
Manager Server system. The datastore acts as a mount point for inserted
media. If an NFS datastore already mounts an enabled NFS datastores
managed by Lab Manager, Lab Manager cannot create the NFS datastore on
the Managed Server system and cannot access media hosted on the storage
server. ESX Server does not allow two datastores to share the same NFS
mount.
To address this situation, remove the NFS datastore that is not managed by
Lab Manager.
A situation in which Lab Manager manages conflicting NFS datastores can
arise when you remove an NFS server from Lab Manager and a virtual
machine currently uses that NFS server. (The virtual machine has inserted
media hosted on the NFS server.) Although Lab Manager does not report
errors on the NFS storage server remove operation, the Managed Server agent
cannot remove the NFS datastore because the virtual machine is holding on to
media hosted by the NFS datastore. If you add the NFS datastore to Lab
Manager again, Lab Manager might fail because it is already mounted under
a different name.
To address this situation, eject the media from the virtual machine and
manually remove the NFS datastore from the VI client. You can remove the
datastore from Lab Manager and add it again.
