c. In a FICON environment, log in as root and enter configupload --map to upload port-to-area
|
mapping information. Specify a folder name, when prompted. This command saves the
|
|
port-to-area addressing mode configuration files to the folder specified. Be sure to upload the
configuration using the -map option for a FICON-enabled device if port-bound addressing is used.
|
For more information, refer to the Fabric OS Command Reference.

2.
Connect to the device and log in as admin, using a serial console connection.
Enter haShow to determine which CP blade is active.
|
3.
|
Chassis_1:admin> haShow
|
Local CP (Slot 1, CP1) : Active
|
Remote CP (Slot 2, CP0) : Standby, Healthy
|
HA Enabled, Heartbeat Up, HA State Synchronized
4.
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.
If the active CP blade is faulted, automatic fail over to the standby CP blade should have occurred.
|
5.
Perform the following steps:
|
a. Confirm that the standby CP blade is active using the haShow command.
|
|
b. Power off the faulted CP blade by loosening the captive screws on both ejector handles on the
blade using a #1 Phillips screwdriver. This disconnects power from the blade. The spring-loaded
|
captive screwswill pop out from the slot .63 cm (.25 in.) when fully disengaged.
|
c.
Log into the now active CP blade.
|
|
d. Skip to step 8.
If automatic fail over has not occurred, manually fail over the faulty blade by loosening the captive
|
screws on both ejector handles. As the screws loosen, the blade fails over and the amber status LED
|
will illuminate. Log into the standby CP blade, and skip to step 8.
|
|
6.
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 8.
|
7.
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 illuminated.
|
|
b.
Confirm the completion of the failover by running the haShow command.
Log in to the new active CP blade.
|
c.
8.
Run firmwareShow to note the firmware version of the active CP blade.
|
The firmwareshow command will display a warning message if the firmware versions on the two CP
|
|
blades are not the same.
|
WARNING: The local CP and remote CP have different versions
|
of firmware, please retry firmwaredownload command.

9.
Run haDisable from the active CP blade to prevent failover or communication between the CP blades
|
|
during the replacement.
