'''Mount verification''' is a process of verifying a connection to the volume after an unseccessful I/O. It continues until the volume has been successfully verified or until mount verification timeout expires.

=Causes=
The following can cause mount verification:
* drive problems (such as a failed port)
* disk problems (hardware errors)
* controller/SAN fabric problems
* storage connection problem
* device is write locked manually while a write operation is in progress
* in a multipath configuration, paths to the device are switched

=Symptoms=
When mount verification starts, two messages are sent to the terminals: one to [[OPCOM]] and the other one directly to [[OPA0:]].

=Timeout=
Mount verification (except in case of write locking) continues until it times out. The timeout is controlled with [[MVTIMEOUT]] and [[TAPE_MVTIMEOUT]]

=Disabling=
To disable mount verification on a device, mount it with /NOMOUNT_VERIFICATION.
