Also verify that no zone conflicts are being reported on the inter-switch

links (ISL).

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.

Replace a McDATA FC Switch

To replace a McDATA FibreChannel switch, complete these steps:

1. Stop Matrix Server on any servers that are connected only to the

original switch.

2. If possible, save configuration information from the original switch.

Some items such as the zone configuration are not needed and are just

insurance against further failures. Other items such as the IP address

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 switchʹs 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
