are available elsewhere but might conveniently be captured here. One
way to record the information is to capture the output of a CLI session.
The following commands show the type of data that might be useful:
show ip ethernet for the IP address.
show switch for the fabric operating mode.
show zoning for the zone configuration.
3. After the original switch has been powered down, power up the new
switch and set the IP address to the old switch's address to allow EWS
access. The IP address can be set either from the serial port or by
connecting to the current, possibly default, IP address. Verify that the
new switch responds to the IP address.
4. Connect to the EWS and take the switch offline using the Operations >
Switch > Online State tab.
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 information 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 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. For example, you can use the PowerPath powermt
command to do this.
