The Mount command logically connects devices to Ancillary Control Processors (ACPs). There are three 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. Files-11 Format: MOUnt dev:...

(FT) /VI Display volume information on the TTY. (F) /WIN=retrieval-ptr-cnt Specify number of mapping ptrs to be allocated. For more detailed help on a specific keyword, type HELP MOUNT keyword-name 2 ACP The format of the ACP keyword is: (FTN) /ACP=taskname Where taskname is the name of the Ancillary Control Processor to use with the volume. The default depends upon device type: Files-11 disks & DECtapes: ddnnF1 if it exists else Files-11 disks: F11ACP & Files-11 DECtape: DTAACP if it exists else Files-11 DECtape: F11ACP Magtape: MTAACP Network: NT.... 2 DENS The format of the DENS keyword is: (FT) /DENS=density Acceptable & Default densities depend on the device type:- Device Type Acceptable densities Default =========== ==================== ======= TE16 800 (LOW) or 1600 (HIGH) 800 TS04 1600 1600 TU45 800 (LOW) or 1600 (HIGH) 800 TU77 800 (LOW) or 1600 (HIGH) 800 RX02 LOW or HIGH HIGH 2 EXT The format of the EXT keyword is: (F) /EXT=block-count When a file exhausts its currently allocated space on the volume, it is extended by the specified number of blocks. Default is taken from the volume's home block. 2 FOR The format of the /FOR keyword is: (FT) /FOR This keyword indicates a foreign volume - the format of the volume and/or the ACP that controls the volume are not DEC standard. When mounting a foreign volume an ACP name must be specified. 2 FPRO The format of the FPRO keyword is: (FT) /FPRO=[system,owner,group,world] Default protection for files is set as specified. The default value of the FPRO keyword is taken from the volume's home block for disk volumes, and is [RWED,RWED,RWE,R] for tape volumes. Each subfield in the keyword may be one to four letters, taken from {R,W,E,D}. The presence of a code character allows that access for the group of users specified by the position of the characters in the keyword value. 2 LRU The format of the LRU keyword is: (F) /LRU=FCB-count The number of directory File Control Blocks kept in memory by the ACP is set to the proper value. More = faster but more memory. Default is taken from the volume home block. 2 OVR The format of the (privileged) OVR keyword is: (FT) /OVR If this keyword is present, label processing is suppressed so that a volume can be mounted without specifying a label. The label of a volume can be printed by mounting it with the keywords /OVR/VI. 2 OVRFSID The format of the OVRFSID keyword is: (T) /OVRFSID If this keyword is present, existing file set identifiers are overridden. 2 OVREXP The format of the OVREXP keyword is: (T) /OVREXP If this keyword is present, the expiration date of the volume is overridden. 2 PARM The format of the PARM keyword is: (FT) /PARM="user parameters" The mount command uses this keyword to pass non-standard parameters from the command line to a foreign ACP. The user parameter string can consist of up to a maximum of 40 characters enclosed in quotes ("). 2 PRTCL The format of the PRTCL keyword is: (N) /PRTCL=netqork-protocol This keyword allows the user to specify the line protocol to be used by the network. The default is DDCMP. 2 RCK The format of the RCK keyword is: (N) /RCK=algorithm-name This keyword allows the user to specify the name of a redundancy checking algorithm routine. The default is CRC16. 2 TEL The format of the TEL keyword is: (N) /TEL=number This keyword allows the user to specify the telephone number of a line to be a remote node. Up to 12 digits may be specified. The default is null. 2 UIC The format of the UIC keyword is: (FT) /UIC=[group,member] 2 UNL The format of the UNL keyword is: (F) /UNL If this keyword is specified, the volume's index file is unlocked and may be written. Otherwise, the index file is read-only. 2 VI The format of the VI keyword is: (FT) /VI If this keyword is specified, the volume information for the volume is displayed when the mount is completed. 2 WIN The format of the WIN keyword is: (F) /WIN=retrieval-pointer-count The specified number of mapping pointers is allocated for file access windows. Default: if I/O optimizations are in system, as large as necessary if space is available. If I/O optimizations were not selected during SYSGEN, default is taken from volume's home block. 2 EXAMPLES To mount a pack that has a null label on an RK05 drive, selecting no special options: MOU DK1: To mount a magtape volume set at 1600 BPI, overriding expiration dates: 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/VI/LRU=10/WIN=20
