If a Client Can’t Use a Volume After a Fibre Channel
If a client loses its Fibre Channel connection to the SAN (for example, because a
cable is unplugged), the client might not recognize LUNs in an Xsan volume after the
connection is restored. If this happens, restart the client to remount the volume.
If problems persist, restart all SAN devices. Restart RAID systems first, then continue
with SAN controllers, and finally, restart all clients.
To check whether a computer is seeing Xsan volume LUNs:
Open Disk Utility on the computer and look for the LUNs in the list of disks and
From the Command Line
You can also check for accessible LUNs using the
command or the
command in Terminal.
