Initializing the version control file index

Initialize the version control file index (VCFX) so that the VCFX can be referenced through the /sys/tpf_pbfiles symbolic link in the system pseudo-file system (SYSFS). For more information about setting up SYSFS, see Mounting a PROCFS or SYSFS.

Procedure

  1. Create the subdirectory for program base unique files on the z/TPF collection support file system (TFS) by entering ZFILE mkdir /tpf_pbfiles/n, where n is the TFS subdirectory for program base unique files in the range of 1 - 8.
    For example:
    • zfile mkdir -m 755 /tpf_pbfiles
    • zfile mkdir -m 755 /tpf_pbfiles/1
    • zfile mkdir -m 755 /tpf_pbfiles/2
    • zfile mkdir -m 755 /tpf_pbfiles/3
    • zfile mkdir -m 755 /tpf_pbfiles/4
    • zfile mkdir -m 755 /tpf_pbfiles/5
    • zfile mkdir -m 755 /tpf_pbfiles/6
    • zfile mkdir -m 755 /tpf_pbfiles/7
    • zfile mkdir -m 755 /tpf_pbfiles/8
  2. Verify that SYSFS is mounted by entering the ZFILE mount command. You can display the /sys/tpf_pbfiles symbolic link in the output by entering ZFILE ls -l /sys.
  3. Mount the VCFX by completing the following steps:
    1. Create the mount point for VCFX by entering ZFILE mkdir -m 755 /vcfx.
    2. Mount the VCFX on the /vcfx directory by entering ZFILE mount -t vcfx /vcfx.
    If you enter the previous commands, the mount information is registered to the restart mounted file system table (MTAB), which causes the file systems to be remounted automatically after each IPL. Therefore, you need to enter these commands only once.
