Online Replacement of a FibreChannel Switch

When a matrix includes multiple FibreChannel switches, you can replace

a switch without affecting normal matrix operations. The following

conditions must be met when performing online replacement of a

FibreChannel switch:

• The replacement switch must be the same model as the original switch

and must have the same number of ports.

• The FC connectors must be reinserted in the same location on the new

switch. For example, the FC connector that was plugged into port 1 on

the original switch must be plugged into port 1 on the new switch.

• Matrix Server 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 matrix,

replace the switch, and use mxconfig to reconfigure the new switch into

the matrix.

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 Matrix Server 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.
