1 MOUnt 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.

Type AID MOUNT EXAMPLES for examples of usage. 2 KEYWORDS In the following list of keywords, each keyword is preceded by a code that indicates the device type for which the keyword is legal. "F" indicates Files-11, and "T" indicates magtape. (FT) /ACP=option Specifies the ACP to be used. (FT) /CHA=[parameter(s)] Specify Characteristics (FT) /DENS=tape-density Specifies tape density: 800, 1600, or 6250 bpi. (F) /EXT=block-count Specifies file extension increment. (FT) /FPRO=[s,g,o,w] Specifies default file protection codes. (F) /LRU=directory-count Specifies number of directories to be accessed. (FT) /OVR Overrides label processing. (T) /OVREXP Overrides expiration date. (T) /OVRFSID Ignores existing File Set Identifiers. (F) /UNL Unlocks volume index file. (F) /WIN=option Specify number of mapping pointers. to be allocated for file windows. For more detailed help on a specific keyword, type AID 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 CHA The format of the /CHA keyword is: (FT) /CHA=[option(,option,option)] where options can be: FOR A Foreign volumn ATCH Device may be attached DCF Device control functions permitted 3 DENS The format of the /DENS keyword is: (FT) /DENS=density where density is 800, 1600, or 6250 bpi. 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 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 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 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 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 UIC The format for the /UIC keyword is: (FT) /UIC=[ggg,uuu] This option specifies the volumn UIC to be used for the duration that the volume is mounted. 3 UNL The format for the /UNL keyword is: (FT) /UNL This option specifies that the volume's index file is to be left unlocked, thus giving task write access to the index file. 3 WIN The format of the /WIN keyword is: (F) /WIN=n where n is the number of retrieval pointers to be kept in each window block for each open file on this volumn. Increasing this number speeds ac- cess, particularly to randomly accessed files, at the expense of system dy- namic memory. 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 MOU MM0:PAYROLLVOL1/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
