If these conditions are not met, you will not be able to perform online replacement
of the switch. Instead, you will need to stop the cluster, replace the switch, and use
mxconfig to reconfigure the new switch into the cluster.
Consult your switch documentation for the appropriate replacement procedure,
keeping in mind that the above requirements must be met. However, if this
documentation is not available, the following procedures describe a method to replace
a switch.
Replace a Brocade FC switch
To replace a Brocade Fibre Channel switch, complete these steps:
1. Stop HP Scalable NAS on any servers that are connected only to the original
switch.
2. If possible, save the configuration information on the original switch. Use the
configUpload command.
3. Record the IP address of the original switch. Use the ipAddrShow command.
4. Back up the zone configuration information, either from the original switch or
from another switch in the fabric. Use the cfgShow command and record its
output.
5. Connect the power and either the Ethernet or the serial console cable to the new
switch.
6. Log on to the new switch.
7. Disable the switch with the switchDisable command.
8. Disable any stale active configuration on the new switch with the cfgDisable
command.
9. Verify that the Brocade licenses are installed by using the licenseShow
command. The new switch should have the same kind of license as the rest of
the fabric.
10. Clear any stale zone configuration on the new switch with the cfgClear
command.
11. Save the clean configuration with the cfgSave command.
12. Configure the new switch. If you saved the original configuration with the
configUpload command, use the configDownload command to restore it.
Otherwise, use the configure command. (You may need to consult your site’s
SAN administrator or your Brocade representative for the correct configuration
information.)
