5. FCHECK Syntax

FCHECK [ -RATE nnn ] [options] { [-FILE file]

[-VOL volume]

[-SUBVOL subvolume]

[ * ] }

[ -HELP ]

–RATE controls the rate at which the file checking is performed. The minimum value is 1

(slowest) and the maximum value is 100 (fastest). The larger the specified value, the

greater the impact on system performance.

options = any combination of the following options, separated by spaces:

–Q Quiet mode

–S Summary mode

–SIZE Provides information on space usage

–FINDBAD Combines –Q and –S

–FIXEOF Reduces EOF to exclude blocks with invalid checksums

–NOBTREE Skips B-tree checks for key-sequenced files or tables

–SCAN Performs scan check

–FASTSCAN Performs scan check without checksum validation

–FULLSCAN Performs scan check followed by data validation

–SCANPRIMARY Performs scan check of only the primary drive

–SCANMIRROR Performs scan check of only the mirror drive

Use one of the following options to specify the file set(s) to be checked by FCHECK:

–FILE [\system.][$volume.][subvolume.]{filename}

–VOL [\system.]{$volume}

–SUBVOL [\system.]{$volume.subvolume}

* Check all files in the current $volume.subvolume

–HELP = print this information

You can specify –FILE $volume.SYS00.DIRECTRY to check the directory.

To limit impact to higher priority workloads, initiate FCHECK at a priority less than the

higher priority workloads.
