Creating legacy SCSI and FCP robotic controls on HP-UX
Before you create the device files, you must do the following:
Install and configure the sctl driver. For more information, see the HP-UX scsi_ctl(7) man page.
The sctl driver may be the default pass-through driver on your system. If so, you do not have to configure the kernel to use the sctl pass-through driver.
Attach the devices.
Examples of how to create the device files are available.
To create sctl device files
- Invoke the ioscan -f command to obtain SCSI bus and robotic control information.
Examine the output for the card instance number and the SCSI ID and LUN of the robotic device, as follows:
The instance number of the card is in the I column of the output.
The H/W Path column of the changer output (schgr) includes the SCSI ID and LUN. Use the card's H/W Path value to filter the changer's H/W Path entry; the SCSI ID and the LUN remain.
- Determine the character major number of the sctl driver by using the following command:
lsdev -d sctl
Examine the output for an entry that shows sctl in the Driver column.
- Use the following commands to create the device file for the SCSI robotic control:
mkdir /dev/sctl cd /dev/sctl /usr/sbin/mknod cCARDtTARGETlLUN c Major 0xIITL00
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.
