Symptom Cause/Solution
The dialog box shown
above appears when
you try to unassign a
SAN Manager LM
device.
There are open files or folders, or one of the volumes on the device
is being held open. Shut down any applications, services, or third-party
drivers that may be holding open files, folders, or a volume.
The file server is sharing the device or a folder on the device. Log off
remote clients and stop sharing the device or folder.
Ftdisk (fault tolerant disk driver) may be running. Try the following
solutions:
– Shut down the host before unassigning storage, then restart the host.
– Use the Devices Control Panel to disable Ftdisk and reboot the host.
Note that stripe- and volume-sets will not be accessible with Ftdisk
disabled.
A disk filter may be running. Try the following solutions:
– Shut down the host before unassigning storage, then restart the host.
– Determine which disk filters are running and deactivate them if they are
not being used. Restart the host after deactivating any disk filters.
A software crash or operating system resource leak may leave open
handles to a device. Restart the host.
