Changing LUN Offset
When a system has a HSC or in a VAX cluster it will be necessary to
change the LUN (Logical
Unit Number) offset. Each MSCP drive requires a
different Unit Number so that the unit numbers are not duplicated. If there
are
no other MSCP controllers in the system, the L UN offset can be o.
If there exists another MSCP controller with four drives (0 to 3), then the LUN
offset should be four or above. In the case that LUN offset is equal to 10, SCSI
ID 0 will be DUBIO and SCSI ID 1 will be DUB1l. The drives will show up as
such DUAO, DUAl, DUA2, DUA3, DUBIO, DUB11 (see section, "SCSI ID for
Target Drives"
in Chapter 3 for explanation).
1 Select option 1 from the main menu for disk drives; 6 for tape drives.
2 Enter the new value for LUN offset at the statement: PRESENT LUN
OFFSET = 0, ENTER NEW VALUE:
