About legacy robotic control device files
For SCSI robotic control, NetBackup can use the /dev/sctl device files. The device file names have the following format:
/dev/sctl/cCARDtTARGETlLUN c Major 0xIITL00
Where:
CARD is the card instance number of the adapter.
TARGET is the SCSI ID of the robotic control.
LUN is the SCSI logical unit number (LUN) of the robot.
Major is the character major number (from the lsdev command).
II are two hexadecimal digits that represent the card instance number.
T is a hexadecimal digit that represents the SCSI ID of robotic control.
L is a hexadecimal digit that represents the SCSI LUN of the robotic control.
A library may have more than one robotic device. Each robotic device requires a device file.
