9 FSCHECK
The file system check utility (FSCHECK) is a native mode program used to detect and repair
inconsistencies found in the file directories and file label tables of the MPE/iX operating
system and to display the file extent map. It is a
standalone utility and should be the only
program running on the system when it is in use.
FSCHECK also provides a consistent MPE/iX subsystem interface, including LISTREDO,
REDO, DO, USE, DEBUG, and LOG functionality.
WARNING Do not use this utility without proper service center support.
Unauthorized use will void your warranty and may cause data loss!
Operation
There are two parts to the FSCHECK utility, the program and the message catalog. The
program can reside in any group and account, but the message catalog must reside in
MPEXL.TELESUP. Each version of the program has a unique message catalog, and the
catalog contains a version ID to prevent the mixing of incompatible programs and catalog
versions. If the message catalog is not in MPEXL.TELESUP, use a file equation to redirect it
to the correct file.
To execute the FSCHECK utility, type FSCHECK at the MPE/iX prompt. You can also invoke
FSCHECK with the MPE/iX RUN command using the INFO parameter to pass commands. The
group and account in FSCHECK that is being run should have PM, MR, DS, and PH
capabilities.
The FSCHECK utility uses the formal file designators FSCHKIN and FSCHKOUT for input and
output respectively. The default input file is $STDINX and the default output file is
$STDLIST, though you can use file equations to redirect them to other files.
On the following pages, each of the FSCHECK commands is listed in alphabetical order.
String sequences (tokens) in brackets next to the command name indicate abbreviations
for the command.
