The general form of the initialize volume command is: INItvolume ddn:volume-label where: ddn is the device name and unit number of the volume to be initialized. If there are too many options to fit on one command line, the line may be continued by ending each line except the last with a hyphEN ("-"). The volume on the specified device is initialized with the given label. Options may be specified to control the parameters that the volume is initialized with. Note that only the DENS option is valid when initializing a magtape. DEFAULTS and OPTIONS are qualifiers for INITVOLUME. 2 DEFAULTS The following defaults apply to the INITVOLUME command: OPTION DEFAULT ------ ------- /BAD No bad block processing /CHA No special characteristics /DENS Device-dependent, for full list type HELP INITVOLUME DEFAULTS DENS /EXT /EXT=5 /FPRO /FPRO=[RWED,RWED,RWED,R] /INDX Device-dependent, for full list type HELP INITVOLUME DEFAULTS INDX /INF Device-dependent, for full list type HELP INITVOLUME DEFAULTS INF /LRU /LRU=3 /MXF Device-dependent, for full list type HELP INITVOLUME DEFAULTS MXF /PRO /PRO=[RWED,RWED,RWED,RWED] /UIC /UIC=[1,1] /WIN /WIN-7 3 MXF The following device-dependent defaults apply to the MXF parameter of the INITVOLUME command: Device initialized Default value for MXF ------------------ --------------------- DP: RP02 Disk 2460 RP03 Disk 4920 DB: RP04/RP05 Disk 10567 RP06 Disk 20956 DF: RF11/RS11 Disk 62 DR: RM02/RM03 Disk 8099 RM80 Disk 15294 RP07 Disk 25600 DK: RK05 Disk 294 DM: RK06 Disk 1668 RK07 Disk 3308 DS: RS03 Disk 62 RS04 Disk 125 DL: RL01 Disk 629 RL02 Disk 1259 DT: DECtape 34 DX: RX01 Disk 29 DY: RX02 Disk 60 3 DENS The following device-dependent defaults apply to the DENS parameter of the INITVOLUME command: Device initialized Default value for DENS ------------------ ---------------------- MM: TU16 Tape 800 BPI TE16 Tape 800 BPI TU45 Tape 800 BPI MF: TU78 Tape 6250 BPI MS: TS04 Tape Drive Density DX: RX02/03 Disk Current Disk Density For the TS04 tape drive (MS:), the density switch can only be used to verify that the tape drive can operate at the specified density.

Under 11-D, device can be attached by one task or group for exclusive use. /CHA=[DCF] Unused by RSX-11M, included for 11-D compati- bility. Under 11-D, device control functions are permitted on the volume. /CHA=[ATCH,DCF] Unused by RSX-11M. Select both of the above options. The default is no special characteristics. 3 DENS The legal formats of the DENS option are: /DENS=800 Select 800 BPI density. /DENS=1600 Select 1600 BPI density. /DENS=6250 Select 6250 BPI density. /DENS=LOW Select lower of two possible densities. /DENS=HIGH Select higher of two possible densities. Default: Device dependent. For full list, type HELP INITVOLUME DEFAULTS DENS 3 EXT The format of the EXT option is: /EXT=block-count If a file exhausts its allocated space, it is extended by "block-count" blocks. Default: /EXT=5 3 FPRO The format of the FPRO option is: /FPRO=[system,owner,group,world] The default protecton for all files created on the volume is set to the specified value. Each of the four fields can contain one or more of the following characters, in the order listed: R To allow the specified group of users read access. W To allow write access to the specified group of users. E To allow extend access to the specified group of users. D To allow delete access to the specified group of users. Default: /FPRO=[RWED,RWED,RWED,R] 3 INDX The format of the INDX option is: /INDX=index-file-position The index file for the volume will be created in the specified position. Access time is normally minimized by /INDX=MID. Legal values for "index-file-position" are: BEG Place index file at the beginning of the volume. END Place index file at the end of the volume. MID Place index file in the middle of the volume. BLK:nnn Place index file beginning at the specified block number. Default: Device dependent. For full list, type HELP INITVOLUME DEFAULTS INDX 3 INF The format of the INF option is: /INF=initial-index-file-size The specified number of file headers is initially allocated in the index file. Default: /INF=16. 3 LRU The format of the LRU option is: /LRU=directory-preaccess-count The specified number of 512-byte directory buffers will be kept in core when the volume is mounted in order to speed up accesses. Default: /LRU=3 3 MXF The format of the MXF option is: /MXF=file-count The maximum number of files allowed on the volume is set to the specified value. The maximum legal file-count is device dependent and can be found by typing HELP INITVOLUME OPTIONS MXF MAXIMUM. Default: Device dependent. For full list, type HELP INITVOLUME DEFAULTS MXF 4 MAXIMUM The following is a list of maximum legal values for the MXF option: Device being initialized Maximum value of MXF ------------------------ -------------------- DB: RP02 Disk 10000 RP03 Disk 20000 RP04/RP05 Disk 42949 RP06 Disk 65536 DF: RF Disk 256 DK: RK05 Disk 1200 DM: RK06 Disk 6781 DS: RS03 Disk 256 RS04 Disk 512 DT: DECtape 144 3 PRO The format of the PRO option is: /PRO=[system,owner,group,world] The specified volume access rights are extended to the specified groups of users. Each field (system, owner, etc.) controls one group of users and contains one or more of the characters given below, in the order given below: R Allow read access W Allow write access E Allow extend access D Allow delete access Default: /PRO=[RWED,RWED,RWED,RWED] 3 UIC The format of the UIC option is: /UIC=[group,member] The volume's owner UIC is set to the specified UIC. This feature is not used by RSX-11M; it is included for RSX-11D compatibility. Default: /UIC=[1,1] 3 WIN The format of the WIN option is: /WIN=retrieval-pointer-count The number of file mapping windows allocated upon mounts is set to the specified value.
