Recording critical SAN384B-2 information

Back up the SAN384B-2 configuration before you replace a CP blade. Refer to the
Fabric OS Administrator's Guide for backup information.
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:
SAN384B-2:admin> hashow
Local CP (Slot 5, CP1) : Active
Remote CP (Slot 4, 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). 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.
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 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 the firmwareShow command to note the firmware version of the active
CP blade.
The example below 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.
SAN384B-2_120:root> firmwareshow
Slot Name
-------------------------------------------------------------
4 CP0
5 CP1
WARNING: The local CP and remote CP have different versions
of firmware, please retry firmwaredownload command.
SAN384B-2: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 chassis configuration to a
specified FTP server. Enter information at the prompts.
a. Run the fosConfig --show command to determine if virtual fabrics are
enabled. If so, run the configupload -vf command. This command uploads
the SAN384B-2 virtual fabric data.
b. If virtual fabrics are not enabled, run the configUpload command. This
command uploads the SAN384B-2 configuration.
