Configuring Redundant Path
Step Description Check
1
Connect the Fibre Channel cable from the new Fibre Channel HBA in the server to the
port on the HP SAN switch.
F
2
Connect the Fibre Channel cable from the new MSA controller to the port on the HP
SAN switch.
F
3
Configure the FC switch zoning to include the new MSA controller and new FC HBA (if
not already configured).
F
4
Create a new connection table on the disk array by performing one of the two
following commands from the Tru64 V5.1B operating system:
# hwmgr -scan comp -clus
# scu scan edt (from each node)
F
5
Verify that there is a connection from the MSA controller to the server HBA, and that
the host WWPN is the same as the WWPN of the Tru64 server.
From the CLI of the second controller, enter: show connections
Example display:
CLI>show connections
Connection Name: HBA1
Host WWNN=20000000-C93673BA
Host WWPN=10000000-C93673BA
Profile Name=Tru64
Connection Name: <Unknown>
Host WWNN=50060B00-00225CB1
Host WWPN=50060B00-00225CB0
Profile Name=default
The connection to the second controller displays default settings.
F
6
Assign a name and profile type to the connection (the additional HBA connected to the
second MSA array controller.)
From the CLI, enter:
add connection <name> WWPN=<WWPN> profile=<type>
Example display assigning a connection name of HBA2:
CLI>add connection HBA2 WWPN=50060B00-00225CB0 profile=Tru64
Connection has been added successfully. Profile Tru64 is set
to the new connection.
