NAMEst — shared tape administration DESCRIPTIONThe st command provides users with a command-line interface to check the status of a shared tape device or to reclaim a shared tape device from a host system that has failed while holding a reservation on the shared tape device. The st command can also be used for the same purpose on shared library robotic devices. To use the st command you must have root user id. Please see examples below for usage. Optionsst recognizes the following options and arguments:
EXAMPLESst -f /dev/scsi/st_device -s The following shows three examples of output from the above command. Device is reserved by another host The above output indicates that the shared device is reserved by another host and is therefore unavailable at this time. Device not ready The above output indicates that the shared device is not ready for use at this time. Device is OK and available The above output indicates that the shared device is ready for use at this time. To reclaim a shared tape/library device from a failed host, the following command can be used: st -f /dev/scsi/st_device -r WARNINGSThe -r option must be used with care. When reclaiming devices, it must be ensured that the host from which the device is being reclaimed has in fact failed, as data may be lost as the result of reclaiming a device that is currently in use by another host. DEPENDENCIESThe sctl SCSI pass-through driver must be configured in the kernel before this command can be used to administer the shared tape device. See scsi_ctl(7). |
