5. Make the switch operating mode and domain ID acceptable to the

original fabric. This can be done either by consulting the fabric or by

taking the values from the data saved in step 2. This procedure might

include changing the default zone setting as directed by EWS when

changing interoperation mode. Any existing zone configuration on

the new switch should be removed to allow the fabric to properly

communicate current zoning when the switch joins the fabric.

6. Add the private community to the Configure > Management > SNMP

tab and ensure that it is write enabled.

7. Connect the FC connectors to the new switch. Be sure to plug them

into the same ports as on the original switch.

8. Bring the switch online. The new switch should now connect to the

rest of the fabric. Verify that the HBAs on the servers log into the new

switch in the expected locations.

9. Verify that the new switch has been configured into the matrix. Run

the /opt/polyserve/sbin/mxmpio status command, which shows

whether failover is enabled or disabled. (See mxmpio(8) for details.)

10. Verify that I/O operations are successful via the new switch. Mount a

psd device, and then use mxmpio to set its active path to one of the

paths that goes through the new switch. Then perform I/O operations

such as creating or deleting files on the mounted psd device.
