Use this command to mount a tape. When you mount a tape, a symbolic
tape name and the associated tape label are assigned to a physical tape
device. The header labels for the tape on the tape device are created
or checked as appropriate.
Requirements and Restrictions
- You cannot mount a standby tape without a corresponding active
tape.
- When mounting the first tape volume of a multiple-volume input file,
ensure that the information in the header label agrees with the corresponding
information in the tape label. (That is, do not specify the BP
parameter to mount the tape.) If this information does not agree, you
cannot switch to a previous tape volume (backward tape switch). You
can, however, use this command to change the options that are defined in the
tape label, if necessary.
Format
- tape
- is a 3-character tape name. The first 2 characters are alphabetic
and the 3rd character is alphanumeric.
- Note:
- You cannot specify a tape name of ALL, XXX, or YYY.
- cuu
- is a 3-digit hexadecimal tape device address.
- A
- mounts the tape as an active tape.
- S
- mounts the tape as a standby tape.
- Note:
- A corresponding active tape must exist before you can mount a standby
tape.
- I
- mounts the tape as an input tape.
- O
- mounts the tape as an output tape.
- SL
- mounts an input tape when it has standard header labels but the tape label
indicates that it has no standard header labels.
- NL
- mounts an input tape when it has no standard header labels but the tape
label indicates that it has standard header labels.
- BP
- allows you to mount an output tape before it expires, to mount an input
tape when the tape label and standard header labels conflict, or to mount an
input tape that has a VOL1 label but no HDR1 label.
- D38K
- see F38K parameter.
- D38K2
- see F38K2 parameter.
- F38K
- allows the tape to be read or written in a format with an operating
density of 38K bytes per inch (Bpi).
- F38K2
- allows the tape to be read or written in a format with an operating
density of 38K Bpi in 3480-2 XF format.
- F16X128
- allows the tape to be read or written in a format of 16 tracks per pass
and 128 total tracks.
- COMP
- specifies that the output tape is written in compacted mode.
- Note:
- This parameter is not valid for input, standby, or alternate (ALT) tapes, or
when mounting a tape on a tape device where the improved data recording
capability (IDRC) feature is not installed or enabled.
- NOCOMP
- specifies that the output tape is written in uncompacted mode.
- Note:
- This parameter is not valid for input, standby, or ALT tapes.
- BLK
- specifies that the tape is written or read in blocked mode.
Notes:
- This parameter is not valid when mounting standby or ALT tapes.
- You must mount RCP tapes as BLK tapes.
- NOBLK
- specifies that the tape is written or read in unblocked mode.
- Note:
- This parameter is not valid when mounting standby or ALT tapes.
- OVerlay
- converts the ALT tape that is mounted on the specified tape device to the
specified tape name.
- Note:
- If an error occurs while converting the ALT tape, the ALT tape is
dismounted.
Additional Information
- The tape options that are currently defined in the tape label are applied
to the tape unless you specify new values for these options when you enter
this command.
- The special tape name ALT designates a common standby output tape.
You can mount ALT tapes in place of standard output tapes as long as the tape
densities are the same. You must mount ALT tapes as active output
tapes. You can mount any number of ALT tapes.
Examples
The RTB tape is mounted on the specified tape device in the following
example.
+--------------------------------------------------------------------------------+
|User: ZTMNT RTB 483 |

The BP parameter is required to mount the RTC output tape in the following
example because the RTC tape has not expired.
