Mounting a BFS directory on OS/2

Examples

These instructions assume that PCNFSD is available on your NFS server.

  • To work with text files that can be used from both CMS and OS/2:
    MOUNT -lvmuserid x: hostname:/../VMBFS:FPCOOL:ROOT/u/jake,trans=yes,xlat=POSIX

  • To use a BFS directory as a repository for binary files:
    MOUNT -lvmuserid x: hostname:/../VMBFS:FPCOOL:ROOT/u/jake,trans=no

Hints and Tips

  • See MOUNT command, MOUNTPW command, and UMOUNT command, for complete syntax descriptions. Still having trouble? Try Diagnosing Mount Problems.

  • You can use any LOGON BY privileges defined for your VM user ID. See the userid= and by= parameters on the MOUNT command for more information.

  • At the prompt enter the logon password for the VM user ID specified on the -l OS/2 option. Be careful about submitting too many MOUNT requests with an invalid password. The VM system may disable a user ID if too many attempts are made to verify a userid/password combination.

  • If PCNFSD is not available on your NFS server, add the userid= and password= parameters to your mount string. On the password= parameter, enter the logon password for the VM user ID specified on userid=. Be careful about submitting too many MOUNT requests with an invalid password. The VM system may disable a user ID if too many attempts are made to verify a userid/password combination.

    Also use the -unnnn and -gnnnn OS/2 options instead of the -l OS/2 option, entering the UID and GID associated with the VM user ID specified on the userid= parameter.

  • Do not use the -v option on an OS/2 MOUNT command or your UID and GID will be set improperly.

  • For hostname:, use the system on which the file pool server resides to avoid unnecessary overhead.

  • You must use a fully-qualified BFS directory name on the MOUNT command. Be careful - case is important!

  • If you want EBCDIC-ASCII translation to be done based on the value of the file extension, use the trans=ext parameter instead of trans=yes or trans=no.

  • Use the SMSG command to obtain more information if you receive an error but don't understand what went wrong when using a BFS directory.

  • If you created a text file using an OS/2 editor and want to use the XEDIT command to edit it from CMS, it may be necessary to use the BFSLINE /X'0D15'/ option.

  • NFS server support for BFS is available only on NFS servers running at least TCP/IP level 310 for VM/ESA Version 2 Release 3.
