Preparing the Host System
3–11HSG80 ACS Solution Software Version 8.7 for Compaq Tru64 UNIX Installation and
Configuration Guide
3–11
• 19 is the major number
• 150 represents the minor number
• 2 is the SCSI host-side bus number
• 0 is the drive number as listed in the Configuration File
• 1 is the Controller Target ID
• 1 is the LUN number
If the only output that is returned from the file command is the major and minor
number, then either the device is not answering or the device special file does not have
the correct minor number. Check the minor number to be sure that it matches the host
SCSI bus number, the Controller target ID, and the Controller Unit LUN.
If an error occurs regarding the disk label, there is good probability that the device can
be accessed. This error can usually be fixed by creating the disk label with the Tru64
UNIX disklabel utility.
NOTE: For major and minor number calculations see “man SCSI” in the UNIX online help.
Reading from the device, dd
Check the created device using dd on the ‘raw’ device to see if there is a full
communication path between devices and Tru64 UNIX. For example:
For V4.0G
# dd if=/dev/rrzb17a of=/dev/null
For V5.1x
# dd if=/dev/rdisk/dsk7a of=/dev/null
This will read the full disk-device until you press Ctrl-c or the device has been read. If
the test is successful, the device activity LED (green) on the device lights. If the device
consists of multiple disks, all these will be lit.
scu polling program
You can use the SCSI CAM Utility (scu) program to see which HSG80 units are
available to the Tru64 UNIX Operating System. It is located in the /sbin directory and
documented in the REF Pages.
