Running the tctl Command

Running the tctl Command

Use the tctl command to verify that system commands can be performed on a device.
This is especially useful for those types of devices that are not accessible using the tapeuti 1 command (for example, the tape drives in the 7331 Tape Library, 7336 Tape Library, or 7337 Tape Library).

To use the tctl command, at the AIX command line type the following and press Enter (where x equals the number of the tape library and the subcommand is one of the subcommands from the list that follows):

tctl -f/dev/rmtx subcommand

In a library with a resource name of rmtO, to rewind and unload a tape cartridge, type the following and press Enter.

tctl -f/dev/rmt0 rewoffl

The following are subcommands that can be used in a tctl line command.

weof	Write end of file
fst	Forward space file
fsr	Forward space record
rewind	Rewind
rewoffl	Rewind or offload (unload)
eof	Erase end of file
bsf	Backward space file
bsr	Backward space record
offline	Set offline
