AutoAuditOverride An integer value of 1 or 0, sets the Auto Audit Override
configuration parameter to on or off, respectively.
The ACL has an internal database which it keeps up to date. When
powered on with a tape cartridge in the drive, however, the ACL
cannot read the barcode ID of that cartridge until it is unloaded from
the drive.
When the Auto Audit Override configuration parameter is set to off,
the ACL automatically executes a barcode read when it does not
have a barcode ID stored for the tape cartridge it unloads from the
drive. When the Auto Audit Override configuration parameter is set
to on, this functionality is suppressed.
Writer_Note: Bug RWCra01640 erroneously states that 8XX ACLs will not load a tape cartridge with
an unreadable barcode ID, regardless of the Barcode Required Enable configuration
parameter setting.
BarcodeRequired An integer value of 1 or 0, sets the Barcode Required Enable
configuration parameter to on or off, respectively.
When the Barcode Required Enable configuration parameter is set
to on, the ACL will not accept a tape cartridge that does not have a
readable barcode ID; i.e., the ACL will not transfer the cartridge to
a drive (2XX, 4XX) or from an IMEX bin (8XX). When the
parameter is set to off, the ACL accepts all tape cartridges without
regard to barcode ID.
ENVIRONMENT
The ACL management utilities use the following environment variables. Command-line
options always override any environment variables.
$ACL_DEV
Specifies the device special file to use when you omit the -device option.
$RETRY_ON_RESET
Specifies that the ACL management utilities perform one retry automatically when a failure is
caused by a SCSI Bus Device Reset of the ACL. When $RETRY_ON_RESET is not set, an
ACL management utility will perform a retry automatically only if the -retry_on_reset option
is specified on the command line.
EXIT STATUS
The ACL management utilities use the following exit status codes:
