Device Information Example - HP StorageWorks XP10000 - Disk Array Configuration Manual

3. Construct the minor number for each device, using the device information, and enter the file
names in your table. Use the following formula to construct the minor number:
0xxxyz00 where
xx = SCSI bus instance number, y = SCSI target ID, and z = LUN.
4. Display the driver information for the system using the lsdev command.
Example
# lsdev
Character
:
188
#
5. Enter the major numbers for the device drivers into the table. You should now have all required
device and driver information in the table.
6. Create the device files for all disk array devices (SCSI disk and multiplatform devices) using the
mknodcommand. Create the block-type device files in the /dev/dsk directory and the
character-type device files in the /dev/rdsk directory.
Example
# cd /dev/dsk
# mknod /dev/dsk/c2t6d0 b 31 0x026000
# cd /dev/rdsk
# mknod /dev/rdsk/c2t6d0 c 188 0x026000 Create character-type file.
:
#
The character-type device file is required for volumes used as raw devices (for example,
3390-3A/B/C). The block-type device file is not required for volumes used as raw devices.
If you need to delete a device file, use the rm
