permanent files. No recovery possible. Can
occur only when introducing removable devices
after deadstart; contact a si te analyst.

When a VE status error occurs, the device
becomes interlocked. A PP program that
attempts to access that device cannot
complete until the interlock is cleared.
Enter the DSD command VALIDATE to
remove the VE error and interlock.

RESOURCE MOUNTING PREVIEW (E,P.) DISPLAY
The preview display identifies the tapes and packs needed
to satisfy user's requests. In order for this display to be
selected, the magnetic tape subsystem (MAGNET) must be
executing at a control point. Each line in the display
appears in the following format.
no eq pn/vsn usernum ring label status
no FNT ordinal job.
eq Resource type:
MT
Magnetic tape unit (7-track).
HD Magnetic tape unit
(800-cpi,
9-track).
PE Magnetic tape unit (1600-cpi,
9-track).

One- to six-character volume serial number
of the required tape or one- to
seven-character pack nam e of the required
pack. The pn/vsn is obtained from the
user's control statement.

Magnetic tape ring enforcement (if any):
IN Write enable required (ring in).
OUT Write disable required (ring out).
No ring enforcement.
Magnetic tape label requirements (if any):
YES A labeled tape is required.
No label is required.
Operator message indicating an error
condition (refer to message's entry in
appendix B) or a MOUNT request. If
MOUNT appears in this field, the next
volume of a multireel· file should be
mounted. Subsequent reels of a multireel
file must be mounted on a drive of similar
type and on the same channeI(s) as the first
reel of the file. That is, if the first reel of
a file is on a 669 tape unit on channel 13
and 33, all subsequent reels must be on a
669 unit on channels 13 and 33. For
purposes of reel swapping, models 679-2,
-3, and -4 drives (800/1600 cpO and models
679-5, -6, and -7 drives (1600/6250 cpO are
considered different drive types.
Figure 4-11 illustrates the preview display.
TAPE STATUS (E,T.) DISPLAY
The tape status display summarizes the status of all
magnetic tape units in the system. To page the display
forward and backward, use the following commands.
E, T+. Displays next available page.
E, T-. Displays previous page.
t
If the user's VSN request is in the form VSN, file=vsn1=vsn2, the E,P display will display the first volume serial number
(vsn1) as the VSN of the tape which
is
requested. If the second tape (with VSN of vsn2) is subsequently mounted, the
system will assign it to the job, but assignment may not be immediate. The maximum delay is the time a job is rolled out
waiting for a specific VSN (approximately 2
minutes)~
If the job ordinal is known, the job can be rolled in (refer to
ROLLIN,xxx command in section 3).
