13. Connect the FC connectors to the new switch. Be sure to plug them into the same
ports as on the original switch.
14. Set the Ethernet IP address on the new switch to the IP address of the original
switch. Use the ipAddrSet command.
If you had connected to the switch over the Ethernet interface, the session will
be disconnected and you will need to log back into the switch with the IP address
you just configured.
15. Enable the switch using the switchEnable command. The new switch should
now connect to the rest of the fabric.
16. Verify that the HBAs on the servers log into the new switch in the expected
locations. Also verify that no zone conflicts are being reported on the inter-switch
links (ISL).
17. Verify that the new switch has been configured into the cluster. Run the
/opt/hpcfs/sbin/mxmpio status command, which shows whether failover
is enabled or disabled. (See mxmpio(8) for details.)
18. 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.
Replace a McDATA FC switch
To replace a McDATA Fibre Channel switch, complete the following steps.
NOTE:
This procedure uses the McDATA Web interface to perform various Fibre Channel
switch operations. You can also use the McDATA command-line utility to perform
these operations.
1. Stop HP Scalable NAS on any servers that are connected only to the original
switch.
