MOUNT command
The MOUNT command requests that a specified file structure or magnetic
tape set be made available for your job's use.
Format
@MOUNT medium (NAME) dev: /switch(es)
where:
medium is one of the following:
STRUCTURE - for mounting file
structures (disk packs)
TAPE - for mounting magnetic
tapes
dev: is either the structure identification
(or alias), or the tape setname. The
colon after the device name is optional.
/switches are keywords, chosen from the list
below, indicating your choice of MOUNT
command options.

MOUNT Command Switches
/CHECK-SETNAME ensures that the setname of the
mounted tapes matches the setname
you specify as the "dev:" argument
to the MOUNT command; otherwise an
error will be generated. For
labeled tapes only.
200
556
800 specifies the density, in bits per
/DENSITY:1600 inch, at which the tape set is to
6250 be read or written. Densities 200
SYSTEM-DEFAULT and 556 are for unlabeled tapes
only. SYSTEM-DEFAULT, one of the
values shown (usually 1600), is
established at system start-up
time.
7-TRACK
/DRIVE-TYPE:9-TRACK specifies the type of drive on
which the tape set is to be
mounted. Labeled tapes must be
mounted on 9-track drives.
ANSI
BYPASS
/LABEL-TYPE:EBCDIC tells the system to read and write
TOPS-20 the tape set according to the
UNLABELED specified label standard: ANSI;
EBCDIC - IBM TYPES (IN READ-ONLY
MODE); TOPS-20 - a superset of ANSI
used in TOPS-20 systems; UNLABELED
- for unlabeled tapes only. BYPASS
(for privileged users only) lets
you read and write any tape,
labeled or unlabeled, without any
label processing.
/NEW tells the system that you are
creating a new file set on an
existing tape set, whose setname is
then changed to be the name you
specify as the dev: argument to
the MOUNT command. (If the tape
set has more than one volume,
remember to specify their volids
using the /VOLIDS or /OPERATOR
switch.) The /CHECK-SETNAME and
/READ-ONLY switches are ignored if
present, and /WRITE-ENABLED is
assumed. Do not give the /START
switch if you give /NEW.
/NOUNLOAD asks the system not to unload a
volume (reel) of tape from its tape
drive when the drive is released by
a volume switch (change of volumes
required by a read or write
operation) or DISMOUNT command.
Use this switch to facilitate
processing when sufficient drives
are available.
/NOWAIT tells the system to return your
terminal to TOPS-20 command level
as soon as you give the MOUNT
command, and to send a message to
your terminal when the request has
been processed. Otherwise, your
terminal waits for the message.
/OPERATOR asks the operator to specify to the
system the volids of the tape set
you wish to mount. Do not use if
you have given the /VOLIDS switch.
/PROTECTION:code specifies a 6-digit octal
protection code for new volumes of
tape written during the current
mount request. The owner always
has full access to his tapes, so
the first two digits are always
interpreted as "77"; also, user
groups and directory groups have no
effect on tape access, so the
middle two digits are always
interpreted as "00". Therefore,
although six digits can be
specified, only the last two digits
affect the tape's protection code.
(If you specify only two digits,
these will be used as the last two
digits of the protection code.)
These two digits should be the sum
of the values corresponding to the
modes of access you want to allow,
chosen from the following list:
40 - read files in the file set
10 - overwrite or modify files
in the file set
04 - append files to the end of
the file set
For tapes of label-type TOPS-20
only.
Default code - 770000
/READ-ONLY ensures that all volumes in the
tape set will be mounted without
write rings, to prevent accidental
erasures.
Default except when /NEW or
/SCRATCH is specified
/REMARK:"remark" sends the specified remark to the
operator when he is notified of
your mount request. The text of
the remark must be enclosed in
quotation marks (" ") and can be up
to three, 80-character lines long
(including the MOUNT command line).
Note that while the entire remark
is displayed on the operator's
terminal, only the first line
appears in the INFORMATION
MOUNT-REQUESTS display.
For structures, the remark will be
sent only if the structure must be
put on line or physically mounted
to satisfy your mount request.
/SCRATCH same as /NEW, except that the
volumes in the file set you create
will be drawn from the pool of
scratch tapes (tapes not presently
owned by a particular user), rather
than from volumes you specify. Use
this switch to create a new file
set when you are not supplying the
volumes of tape to be used.
NUMBER number
/START:VOLID volid tells the system which volume
(reel) of tape to mount first when
satisfying your request. (You must
also give the /VOLIDS switch,
specifying the group of volumes you
will be using.) Use the NUMBER
argument to give the order of this
volume within the group (e.g., 1
for first, 2 for second), or give
the VOLID argument to repeat the
volid explicitly. You can use this
switch to save time and expense
when you know which volume you will
be using first.
Default - NUMBER 1
/STRUCTURE-ID:structure
identification gives the name of the structure as
recorded in the disk(s); used when
you gave an alias different from
the structure identification as
argument "dev:", above. See
Hints - Using the /STRUCTURE-ID
Switch, below. For privileged
users only.
/VOLIDS:volid, volid,... specifies the volids (volume
identifiers) of the volumes (reels)
of tape you want to access. These
must be consecutive volumes,
usually of the tape set specified
as the "dev:" argument to the MOUNT
command. Although you need not
specify every volume in the set,
any volume not specified will not
be accessible. Do not use this
switch if you have given the
/OPERATOR switch. See also
Characteristics - Using the /VOLIDS
Switch, below.
/WRITE-ENABLED ensures that all volumes in the
tape set will be mounted with write
rings.
Default when /NEW or /SCRATCH
is specified
Characteristics
Action of MOUNT STRUCTURE Command
If the Structure Has Already Been Mounted
If the structure for which you give the MOUNT command
is currently mounted, the system simply increases by 1
the mount count (the number of users who have given the
MOUNT but not the DISMOUNT command for the structure),
and returns your terminal to TOPS-20 command level. A
structure is not ordinarily dismounted until its mount
count is 0.
If the Structure Has Not Yet Been Mounted
If the structure for which you give the MOUNT command
is not currently mounted, your request stays in the
mount request queue until it is acted upon by the
operator or until you cancel the request.
Setnames (File Set Identifiers)
The setname, or file set identifier of a set of tapes, is
part of the label information written into each volume of
the set. It is rewritten every time the /NEW or /SCRATCH
switch is included in a MOUNT command. The "dev:" argument
of the MOUNT command becomes the setname in this case. If
you add volumes to an existing tape set, the system uses the
setname of the old volumes as the setname of the new ones.
Using the /CHECK-SETNAME Switch
If you give the MOUNT command to use an existing file
set (you do not specify the /NEW or /SCRATCH switch),
you can give the /CHECK-SETNAME switch to be sure that
the setname written on the tapes matches the setname
you specify as the "dev:" argument to the MOUNT
command. However, because more than one set of tapes
can have the same setname, the /CHECK-SETNAME switch
does not ensure that the correct tape set will be
mounted. For information about ensuring that the
correct tapes are mounted, see Characteristics - Using
the /VOLIDS Switch, below.
Volids (Volume Identifiers)
The volid, or volume identifier of a volume (reel) of
labeled tape, is part of the label information written into
each volume of tape. It is written only once, by the
operator during the tape's initialization procedure, and is
not changed during the life of the tape. (You should also
affix a paper label displaying the volid onto each reel of
tape.) You can get a list of volids for previously specified
or newly written volumes in any mounted tape set by giving
the INFORMATION VOLUMES command for that set.
Using the /VOLIDS Switch
If you give the MOUNT command to use an existing
multi-volume tape set (you do not specify the /SCRATCH
switch), you can give the volid of each volume you want
to use as an argument to the /VOLIDS switch. The
system ensures that the correct volumes of a labeled
tape will be mounted for your job as long as you use
the /VOLIDS switch to specify them. (If the tape set
does not consist of labeled tapes, the system does not
ensure that the correct tapes are mounted.)
The volids must represent consecutive volumes and must
be specified in the order written (oldest first). Note
that in general you cannot rely on any apparent
alphanumerical order when specifying the volids but
must maintain your own list of the volids in each tape
set. (See Hints - Keeping Track of Volids, below.) You
need not specify every volid in the tape set, but any
volume not specified will not be accessible through the
current MOUNT command. See also Characteristics -
Using the /OPERATOR Switch, and Special Cases -
Single-volume Tape Sets, below.
Using the /OPERATOR Switch
You can use the /OPERATOR switch instead of the /VOLIDS
switch when asking the system to mount a multi-volume
set of tapes. The /OPERATOR switch sends a message to
the operator asking him to specify the volid of each
volume himself. You must be sure to supply the
operator with a list of the volids you want him to
specify before giving a MOUNT command that contains the
/OPERATOR switch.
Hints
Checking Whether Operator is Present
You can give the INFORMATION SYSTEM-STATUS command to find
out whether the operator is in attendance and can process
your mount request. Even if the operator is not in
attendance, your request remains valid until he returns and
deals with it in some way.
Using the /STRUCTURE-ID Switch
The /STRUCTURE-ID switch (available only to users with
enabled WHEEL or OPERATOR capabilities) gives the name of
the structure as recorded in the disk(s) of the structure
itself, where it is used by the system for identification.
Be sure that the structure identification is also written
with a felt-tip marker on the upper surface of each disk
pack, and on a gummed label on the pack cover.
Unless you give this switch, the system mounts the structure
with its structure identification as alias. (The alias is
the name you use when specifying the structure in file
specifications and commands; the INFORMATION STRUCTURE and
INFORMATION AVAILABLE DEVICES commands list structures by
alias only.) The /STRUCTURE-ID switch allows an enabled
WHEEL or OPERATOR to mount a structure under a name
different from the one recorded in the structure.
Use this switch for mounting a structure whose structure
identification is the same as the alias of a currently
mounted structure. In such cases give the MOUNT STRUCTURE
command with any unique alias as the "dev:" argument, and
specify the structure identification with the /STRUCTURE-ID
switch. In subsequent file specifications and commands
referring to the structure, use the alias only.
Dummy "dev:" Arguments for Mounting Tapes
If you want to use different tape sets on successive
runnings of a single program, you can refer to those tape
sets as a logical name in the program, and use this logical
name as the "dev:" argument of your MOUNT command when
mounting tapes. As long as you also specify the volid of
each volume of tape with the /VOLIDS switch (or use the
/OPERATOR switch to ask the operator to do so), you need not
give the actual setname of the tape set as the "dev:"
argument to the MOUNT command. The system considers the
"dev:" argument you supply to be a logical name defined as
the mounted tape set. Therefore, your program can access
the tape set using this logical name.
Keeping Track of Volids
Unless your site has a tape cataloging facility, you must
keep your own record of the volids in each of your tape
sets. After creating a file set on a new tape set, i.e, one
not previously owned by you (by giving the MOUNT command and
including the /SCRATCH switch), you should give the
INFORMATION VOLUMES command for the set before giving the
DISMOUNT command. The system will respond by printing a
list at your terminal of the volids of all volumes in the
tape set. Similarly, if you mount an old tape set and then
perform write operations, you should give INFORMATION
VOLUMES before giving DISMOUNT to learn the volids of any
volumes added to the set. Keep an ordered list of these
volids in a disk file in your directory, for use in
subsequent MOUNT commands when you give the /VOLIDS switch.
Special Cases
Single-volume Tape Sets
If the tape set you want to mount consists of a single
volume of tape, you need not give the /VOLIDS or /OPERATOR
switch to specify its volid. You can give the volid as the
"dev:" argument to the MOUNT command.
Structures Unavailable for Mounting
If the operator has given the OPR program command, SET
STRUCTURE UNAVAILABLE for a specified structure, the system
sends an error message including the phrase, "Structure
unavailable for mounting" in response to subsequent MOUNT
commands for the structure.
Restrictions
Using SET TAPE Commands
The TOPS-20 SET TAPE DENSITY and SET TAPE PARITY commands
are applicable to unlabeled tapes only (but see also
Warnings - /DENSITY Switch Has Limited Effect for Unlabeled
Tapes, below). The SET TAPE FORMAT and SET TAPE
RECORD-LENGTH commands are applicable to both labeled and
unlabeled tapes, but to labeled tapes only if they are
mounted using the /LABEL-TYPE:ANSI or /LABEL-TYPE:TOPS-20
switch. In addition, the files that you read from or write
to such a labeled tape must be in 36-bit format, and they
must not have the ;FORMAT attribute as part of their
specification.
Warnings
POP Command Cancels Unsatisfied Mount Requests
If you have given a PUSH command to obtain a new level of
TOPS-20 and then give a MOUNT command within that new level,
a subsequent POP command will cancel your mount request.
However, if the specified structure or tape set has already
been mounted, it will remain mounted despite your POP
command.
/DENSITY Switch Has Limited Effect for Unlabeled Tapes
The /DENSITY switch, when given in a MOUNT command for an
unlabeled tape, ensures only that your tape set will be
mounted on a drive that supports the specified density. It
does not ensure that the tape set will be read or written at
this density. To specify the density at which unlabeled
tapes are to be read and written, give the SET TAPE DENSITY
command.
Effect on Terminal
The MOUNT command with the /NOWAIT switch, leaves your terminal
at TOPS-20 command level. If you have not given the /NOWAIT
switch, your terminal waits until the system has processed your
request, or to return to TOPS-20 command level. This CTRL/C does
not cancel your request.
