Port: Port type and port number (ex: SCSI-2, FC-0).
TID/Lun: For SCSI or BRIDGE port: Target Id Device. For FC port: Lun.
Volume: Virtual volume id, equal to the volume label for labeled volumes.
Device State: Internal device state set by the VTC.
NOT CONFIGURED – not configured by the internal VTC configuration
ACTIVATED – initial communication received from the NonStop, but not yet the
sequence produced by a SCF START TAPE command.
INACTIVE – not polled by the host since three minutes
FREE – operational and free
LOADED – load internally completed, reply READY to host polling
LOADING – the load is being processed, ex: a restore script is running
UNLOADING – volume unload is being processed
LICENSE LIMIT – the port exceeds the license key limitations
NO REPLY – the VTC did not reply to the status request
DOWN – the physical port is down
Load time: Load request timestamp.
Init time (sec): Initialization time up to the transfer of first user data block, in
seconds. This interval includes:
- the time spent internally to load the volume
- the time spent by the NonStop tape system to detect the READY state, and
recognize the label
- the possible delay between the completed tape OPEN and the first tape IO on a
user data block, after tape headers.
Throughput (MB/s): Data throughput since the first user data block, Init time
is excluded from computation.
Write Bytes: Quantity of data written since the volume was loaded, includes
tape labels.
Read Bytes: Quantity of data read since the volume was loaded, includes tape
labels.
Encryption / Decryption: When the encryption is effective, Yes is displayed.
This is shown only when the Encryption option is licensed.
Action: Unload will immediately unload any virtual volume loaded on the
device.
If a tape application is using the device, this action is equivalent to a cancel.
