The MOUNT command logically connects devices to Ancillary Control Processors (ACPs). There are two forms of the MOUNT command, depending on the device being mounted. Note that, if the MOUNT command line is too long to fit on one MCR command line, it may be extended by typing a hyphen at the end of all but the last line (up to a maximum of 255(10) characters.

For more detailed help on a specific keyword, type HELP MOUNT KEYWORDS keyword-name 3 ACP The format of the /ACP keyword is: (FT) /ACP=option where option is the name of the Ancillary Control Processor to use with the volume. The default depends upon the device type: Files-11 except DECtape: F11ACP DECtape: DTAACP Magtape: MTAACP 3 BS The format of the /BS keyword is: (T) /BS=n where n specifies the block size for an unlabeled magnetic tape volume or the block size for files on ANSI labeled tapes that are Level 1 or 2. 3 CC The format of the /CC keyword is: (T) /CC=option where option is the record type for an unlabeled magnetic tape volume. The options are: FOR LIST NONE 3 DENS The format of the /DENS keyword is: (FT) /DENS=density where density is 800, 1600, or 6250 bpi. The default depends on the device type: TE16 /DENS=800 TS11 /DENS=1600 TU45 /DENS=800 (or LOW) TU77 /DENS=800 TU78 /DENS=6250 3 EXT The format of the /EXT keyword is: (F) /EXT=block-count where block-count specifies the number of blocks by which a file can be extended when it exhausts its space allocation. The default is the value specified when the volume was initialized. 3 FOR The format of the /FOR keyword is: /FOR On RSX-11M, /FOR is recommended but not required for working with a foreign volume. On RSX-11M-PLUS, /FOR is required. 3 FPRO The format of the /FPRO keyword is: (FT) /FPRO=(SYSTEM:RWED,OWNER:RWED,GROUP:RWED,WORLD:RWED) or /FPRO=[RWED,RWED,RWED,RWED] Each subfield in the keyword may be one to four of the following letters: R(ead), W(rite), E(xtend), D(elete). In each instance, the absence of the code means that the applicable user is denied the access right. The default values are taken from the volume's home block. 3 HDR3 The format for the /HDR3 keyword is: /[NO]HDR3 /HDR3 specifies whether an HDR3 label is to be written when creating new files. /NOHDR3 is needed only when it is known that the target system cannot handle a tape with an HDR3 label. The default is /HDR3. 3 LABEL The format of the /LABEL keyword is: (T) /[NO]LABEL /LABEL specifies that a magnetic tape is in ANSI format. /NOLABEL specifies that the magnetic tape is unlabeled. The default is /LABEL. 3 LOCK The format of the /LOCK keyword is: (FT) /LOCK=option where option is Virtual (V), Nounload (N), or Unload (U). On RSX-11M, this keyword is valid only for magnetic tape volumes. On RSX-11M-PLUS, the keyword is valid for magnetic tapes and for DB:-, DM:-, and DU:-type disks. 3 LRU The format of the /LRU keyword is: (F) /LRU=directory-count where directory-count specifies the approximate number of directories that will be accessed simultaneously while the volume is mounted. 3 OVR The format of the (privileged) /OVR keyword is: (FT) /OVR For disks and DECtapes, this keyword overrides label processing so that a volume can be mounted without specifying a volume label. For magnetic tapes, this keyword overrides File-Set-ID processing on the first tape of a tape set so that a volume can be mounted without specifying a File Set ID. 3 OVRACC The format for the /OVRACC keyword is: (T) /OVRACC /OVRACC specifies that protection for an ANSI magnetic tape volume is overridden. 3 OVREXP The format for the /OVREXP keyword is: (T) /OVREXP /ONVREXP specifies that the expiration date on the tape volume(s) is overridden. 3 OVRFSID The format for the /OVRFSID keyword is: (T) /OVRFSID /OVRFSID specifies that existing File Set Identifiers on the second and subsequent magnetic tape volumes of a multivolume set are ignored. 3 PARM The format for the /PARM keyword is: (FT) /PARM="user parameters" where "user parameters" instructs the MOUNT command to pass nonstandard parameters from the command line to a foreign ACP. This keyword is valid only with foreign (/FOR) volumes. 3 PRO The format for the /PRO keyword is: (FT) /PRO=(SYSTEM:RWCD,OWNER:RWCD,GROUP:RWCD,WORLD:RWCD) or /PRO=[RWCD,RWCD,RWCD,RWCD] where the protection specification (R,W,C,D) specifies the default volume protection. In each instance, the absence of the code means that the applicable user is denied the access right. The defaults are the values specified when the volume was initialized. 3 PUB The format for the /PUB keyword is: (FT) /PUB /PUB specifies that the volume is accessible by all users depending on the volume and file protection set for the volume. The defaults are: /PUB if the volume is public /SHARE if the volume is not allocated or set public /NOSHARE if the volume is allocated to a user. 3 RS The format for the /RS keyword is: (T) /RS=n where n specifies the number of characters in a record for unlabeled magnetic tape volumes or the number of characters in a record for files on ANSI labeled tapes that are Level 1 or 2. 3 SHARE The format for /[NO]SHARE keyword is: (FT) /[NO]SHARE /SHARE specifies that a volume can be mounted multiple times by one or more users. /NOSHARE specifies that the volume is reserved for dedicated use by the first user who mounted the volume. The defaults are: /PUB if the volume is public /SHARE if the volume is not allocated or set public /NOSHARE if the volume is allocated to a user 3 TR The format for the /TR keyword is: (T) /TR=option where option specifies the kind of character translation used in read and write operations on an unlabeled magnetic tape volume. The options are: NONE No tranalation takes place. EBCDIC Translation from EBCDIC to ASCII for read; ASCII to EBCDIC for write. UT1,UT2, Translation done by user-supplied Translation tables UT3 that have been previously linked to MTAACP. The default is NONE. 3 UIC The format for the /UIC keyword is: (FT) /UIC=[uic] where uic specifies the User Identification Code (UIC) for the volume owner in the form [group,member]. The brackets are required syntax. 3 UNL The format for the /UNL keyword is: (F) /UNL /UNL specifies that the volume index file should be unlocked for write access by a system user. Otherwise, the volume index file is read-only. 3 VI The format for the /VI keyword is: (FT) /VI /VI specifies that the volume information for the volume is displayed when the mount is completed. 3 VOL The format for the /VOL keyword is: (T) /VOL=(list) where list specifies the Volume Identifier (Volume ID) for an ANSI magnetic tape. If you specify more than one Volume ID (for multivolume tape set), the Volume IDs must be separated by commas. 3 WAIT The format for the /[NO]WAIT keyword is: (FT) /[NO]WAIT /WAIT specifies that operator assistance is required for performing the mount. /NOWAIT specifies that no operator assistance is needed during the mount process. The volume must have been previously placed on the device and readied for access (spun up/brought on-line). 3 WIN The format of the /WIN keyword is: (F) /WIN=option where option specifies the number of mapping pointers to be allocated for file windows. The options are: n All files are set up with this default unless overridden on access; the legal values are 1 through 127(10) or the FULL option. USER:n User default value for the volume. INDEX:n Number of pointers to allocate to the index file window. (USER:n,INDEX:n) If n is not the same for both of these, defaults to the user default value for the volume default and to the number specified for the index file. FULL Windows are created that map as much of the file as possible; FULL can be used as n in all of these options. The default is the number of pointers specified in the home block with either the INI or HOME command. 3 WRITE The format for the /[NO]WRITE keyword is: (FT) /[NO]WRITE /WRITE specifies that write operations are allowed on the volume within the limits of volume and file protection. /NOWRITE specifies that write operations are not allowed on the volume. The default is /WRITE. 2 EXAMPLES To mount a pack that has a null label on an RK07 drive, selecting no special options: MOU DM1: To mount a magtape volume set at 1600 bpi overriding expiration dates and using a continuation line: MOU MM(0,1,3):(PAYROLLVOL1,PAYROLLVOL2,PAYROLLVOL3,PAYROLLVOL4,- PAYROLLVOL5,PAYROLLVOL6)/DENS=1600/OVREXP To mount an RP06 for use as the main system device (because of heavy use, we will keep high window and LRU counts): MOU DB0:/OVR/LRU=10/WIN=20
