active dual controllers in HP-UX environments (400677-002, October 2006)

Configuring the redundant path

Step Description Check

Complete any new Fibre Channel cable connections between the MSA and the server.

Initiate a scan of the I/O infrastructure to discover the new connection.

From the server console, enter

ioscan -fnC fc

Record the World Wide Port Name (WWPN) of the newly added host connection to

the MSA. (This information is required to configure a connection name and access the

control list on the second controller.)

From the server console, enter: fcmsutil <fc_device-file>

Example display, using the fcmsutil command and a device file of /dev/td1:

fcmsutil /dev/td1

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 HP-UX 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=hp

Connection Name: <Unknown>

Host WWNN=50060B00-00225CB1

Host WWPN=50060B00-00225CB0

Profile Name=default

NOTE: As highlighted in the example, the connection to the second controller is

recognized, but has an unknown name and undefined profile type.
