17. Verify that the new switch has been configured into the matrix. Run

the /opt/polyserve/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 FibreChannel switch, complete the following steps.

NOTE: This procedure uses the McDATA Web interface to perform

various FibreChannel switch operations. You can also use the

McDATA command-line utility to perform these operations.

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 types 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 its IP address to address of the old switch 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.
