Brocade DCX 8510-4 Backbone Hardware Reference Manual - Manual (Page 71)

Recording critical Brocade DCX 8510-4 information
Back up the backbone configuration before you replace a CP blade. Refer to the Fabric OS
Administrator's Guide for backup information.
NOTE
The following instructions reference specific slot numbers. These numbers will be different between the
DCX 8510-8/DCX and the DCX 8510-4/DCX-4S chassis.
1. Connect to the chassis and log in as admin, using a serial console connection.
2. Enter haShow to determine which CP blade is active. The following example is from a DCX chassis.
DCX_124:admin> haShow
Local CP (Slot 7, CP1) : Active
Remote CP (Slot 6, CP0) : Standby, Healthy
HA Enabled, Heartbeat Up, HA State Synchronized
3. Enter all remaining commands from the serial console for the active CP blade, unless otherwise
indicated. For more information about commands, refer to the Fabric OS Command Reference
4. If the active CP blade is faulted, automatic fail over to the standby CP blade should have occurred.
Confirm that the standby CP blade is active and power off the faulted CP blade, log in to the standby
CP blade, and skip to step 7.
If automatic failover has not occurred, manually fail over the faulty blade by moving the slider to the
off position (to the right in a DCX 8510-4). Then power off the faulted blade, log in to the standby CP
blade, and skip to step 7.
5. If both CP blades are healthy and you want to replace the standby CP blade, log in to the active CP
blade and skip to step 7.
6. If both CP blades are healthy and you want to replace the active CP blade, log in to the active CP
blade and run the following steps:
a)
Run the haFailover command to make the standby CP blade the active blade. The currently
active CP blade becomes the standby blade. Wait until the status LED on the currently
active CP blade is no longer lit.
b) Confirm the completion of the failover by running the haShow command.
c) Log in to the new active CP blade.
7. Run firmwareShow to note the firmware version of the active CP blade.
The following example shows the results of the firmwareshow command when the firmware
versions on the two CP blades are not the same. Note the warning message at the end of the output.
DCX_120:root> firmwareshow
Slot Name Appl Primary/Secondary Versions Status
--------------------------------------------------------------------------
64 CP0 FOS v6.4.0a STANDBY
v6.4.0a
75 CP1 FOS v7.0.0 ACTIVE *
v7.0.0
WARNING: The local CP and remote CP have different versions
of firmware, please retry firmwaredownload command.
DCX_120:root>
8. Run haDisable from the active CP blade to prevent failover or communication between the CP
blades during the replacement.
9. Use the configUpload command to upload the backbone configuration to a specified FTP server.
Enter information at the prompts.
