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.
ATTENTION
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. Type haShow to determine which CP blade is active. The example below 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 failover 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 standby CP blade, and skip to step 7.
If automatic failover has not occurred, manually failover 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
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.
