8. Type the following and press Enter:
show other_controller
NOTE: This command assumes that the maintenance port cable is connected to the top
controller of the pair.
9. Verify the following:
port_2_topology=loop_hard (loop up)
port_2_al_pa=72 (72 negotiated)
NOTE: Refer to the HSG80 documentation if you need more information about the port
topology and ALPA settings.
Assigning Connection Paths for the Primary Path of the Second Cluster
IMPORTANT: If connections are not defined, all new connections (the automatically
generated “!NEWCONXX” connections) will be assigned Unit Offset 0. This will result in all
boxes seeing all drives, minus units that have been reserved by the other cluster. The unit will
be offline in the Disk Administrator.
NOTE: Only the connections in the cluster using port 2 of each controller need to be renamed.
The cluster using port 1 of each controller does not require renaming.
1. Power off all servers connected to the disk array.
2. Power up Server 1 in Cluster 2. (This server should have ALPA 4.)
3. Power up Server 2 in Cluster 2. (This server should have ALPA 8.)
NOTE: Do not power on any server in Cluster 1.
4. From the CLI window, type the following command and press Enter:
show connections
5. Write down the connections that are OL THIS or OL OTHER (OL = Online) for
renaming the connection in step 7.
6. Check the ALPA value of each connection. It should be 4 for Server 1 and 8 for
Server 2 from Cluster 2. If other connections are online, ignore them. The ALPA
is displayed as a six-digit number in the ADDRESS column (000004 or 000008).
