Technical data

HSG80 (!NEWCON50). For example, assume that member
system pepicelli has two KGPSA Fibre Channel host
bus adapters, and that the worldwide name for KGPSA
pga is 1000-0000-C920-DA01. Example 6–1 shows that
the connections for pga are !NEWCON49, !NEWCON50,
!NEWCON54, and !NEWCON56. You can change the name of
!NEWCON49 to indicate that it is the first connection (of four)
to pga on member system pepicelli as follows:
HSG80> rename !NEWCON49 pep_pga_1
13. For each connection to your cluster, verify that the operating system is
TRU64_UNIX and the unit offset is 0. Search the show connection
display for the worldwide name of each of the KGPSA adapters in
your cluster member systems. If the operating system and offsets are
incorrect, set them, then restart both controllers as follows:
HSG80> set !NEWCON49 unit_offset = 0 1
HSG80> set !NEWCON49 operating_system = TRU64_UNIX 2
HSG80> restart other 3
HSG80> restart this 3
.
.
.
HSG80> show connection

1 Sets the relative offset for LUN numbering to 0. You can set the
unit_offset to nonzero values, but use caution. You may not be
able to access storage units if you set the unit_offset improperly.
2 Specifies that the host environment that is connected to the Fibre
Channel port is TRU64_UNIX. You must change each connection to
TRU64_UNIX. This is very important.
_________________ Caution _________________
Failure to set this to TRU64_UNIX will prevent your
system from booting correctly, recovering from run-time
errors, or from booting at all. (In this release, arbitrated
loop configurations cannot boot from storage connected
via Fibre Channel.) The default operating system is
Windows NT, which uses a different SCSI dialect to talk
to the HSG80 controller.
3 Restarts both controllers to cause all changes to take effect.
