Any existing zone configuration on the replacement 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.
To ensure a highly available configuration after the switch has been
replaced, verify that all servers have eligible I/O paths through the
replaced switch. You can use the PowerPath powermt command or the
Secure Path spmgr command to do this.
