HP Integrity Virtual Machines Installation, Configuration, and Administration

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. If the device is unclaimed, a /dev/rscsi file must be created containing numbers
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:
ConstructionMinor Number
Two hexadecimal digits, identifying the controlling interface card by its instance
number. The instance value is displayed in ioscan output, under column I for the
interface hardware type.
CC
One hexadecimal digit identifying the drive (target) address.T
One hexadecimal digit identifying the LUN within the deviceL
Hexadecimal digit zero, for reserved portion of the minor number.0
The following is an example of the tape device:
# /usr/sbin/mknod /dev/rscsi/c6t5d0 c 203 0x065002
5. Use the located or created sctl device file in specifying the attached device.

Attached devices cannot be shared simultaneously across active virtual machines. Only one
active virtual machine can be given a particular attached device at a time. However, like virtual
