HP StorageWorks Clustered File System 3.6.0 Windows Storage Server Edition Administration Guide (403103-005, January 2008)

Chapter 19: SAN Maintenance 258
• HP Clustered File System must be stopped on any servers that are
connected only to the switch to be replaced.
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 FibreChannel switch, complete these steps:
1. Stop HP Clustered File System 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.
