I have 3 x Netware 6.5 sp3 servers running as guest OS's on VMWare ESX
server 2.5.4. Periodically each of the servers will display errors on the
console that the volumes have been deactivated, example below:

Device "[V358-A2-D0:0] VMWare virtual disk rev:1.0" deactivated by driver
due to device failure

Has anyone ever seen this before, I'm guessing it's due to the driver being
used to access the Virtual disks....

Any advice or suggestions would be gratefully received.
