ALTER TAPEDRIVE Command
(Super Group Only)
ALTER TAPEDRIVE determines whether approval must be given for an application to
use a tape drive for bypass label processing mode (BLPCHECK) or no label
processing mode (NLCHECK).
BLPCHECK or NLCHECK remain in effect until another ALTER TAPEDRIVE command
changes the setting in the current session or a subsequent session. Use INFO
TAPEDRIVE to display the current setting of BLPCHECK or NLCHECK for a tape
drive.
You can also use ALTER TAPEDRIVE to assign NonStop Kernel tape drive names to
tape drives in a tape library. (A tape library can be one Library Storage Module (LSM)
or a group of connected LSMs.) Tape library drives can only be referenced in
MEDIACOM commands after they have NonStop Kernel names. Once the names are
assigned, they remain that way until you change them with a subsequent ALTER
TAPEDRIVE command.
\node.$tape
\node.*
is the tape drive name. Include \node when the tape drive is not on your current
default node. Using \node without a tape drive name or an * instead of a tape
name alters all tape drives on a node for BLPCHECK or NLCHECK. When
associating $tape with an LSM address, you cannot use *.
BLPCHECK { ON | OFF }
applies to bypass label processing only:
ALTER TAPEDRIVE [ [ \node.]$tape ]
[ [ \node.]* ]
[ , BLPCHECK { ON | OFF } ]
[ , RESET BLPCHECK ]
[ , LSM drive-address ]
[ , RESET LSM ]
[ , NLCHECK { ON | OFF } ]
[ , RESET NLCHECK ]
[ , RESERVE { ON | OFF } ]
[ , RESET RESERVE ]
