3. Install sctl device files under the /dev/rscsi/ directory using the hpvmdevmgmt command. For
example:
# hpvmdevmgmt -I
4. Locate a /dev/rscsi sctl device file that corresponds to the device slated for attachment.
4a. If the device was claimed, the /dev/rscsi file ends with the same cXtYdZ numbers.
The following is an example of a tape device:
Claimed = /dev/rmt/c6t5d0BEST
SCTL = /dev/rscsi/c6t5d0
The following is an example of media changer device:
Claimed = /dev/rac/c6t0d0
SCTL = /dev/rscsi/c6t0d0
The following is an example of CD/DVD burner device:
Claimed = /dev/rdsk/c4t3d2
SCTL = /dev/rscsi/c4t3d2
Once the /dev/rscsi file has been located, proceed to step 5.
4b. Ifthe device isunclaimed, a /dev/rscsifile must becreated containingnumbers corresponding
to the hardware address.
The following is an example of locating the hardware address for a tape device:
ext_bus 6 0/2/1/0 c8xx CLAIMED
INTERFACE SCSI C1010 Ultra160 Wide LVD A6828-60101
unknown -1 0/2/1/0.5.0 UNCLAIMED
UNKNOWN HP Ultrium Device Hardware Address = 0/2/1/0.5.0
The following shows how the hardware address is broken down into controller, target and device
numbers:
• c is the instance of 0/2/1/0
• ext_bus is 6
• t is 5
• d is 0
• The sctl file to create is /dev/rscsi/c6t5d0
To create the sctl device file, see scsi_ctl(1M).
Use the mknod command, substituting the values in the minor number as noted:
# /usr/sbin/mknod /dev/rscsi/devname c 203 0xCCTL02
Where component parts of the minor number are constructed as follows:
