Recording critical SAN384B information
Back up the SAN384B configuration before you replace a CP blade. Refer to the
Fabric OS Administrator’s Guide for backup information.
1. Login to the functioning CP blade as admin, using either a Telnet or a serial
console connection.
2. Enter haShow to determine which CP blade is active:
swDir: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 one CP blade is faulted, confirm that the other CP blade is now the active CP
blade and log in to the active 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.
d. Run the firmwareShow command to confirm the firmware version of the
active CP blade.
e. Run the haDisable command to prevent failover or communication between
the CP blades during the replacement.
f. Continue with step 7.
7. Enter firmwareShow to note the firmware version of the active CP blade.
8. EnterhaDisable from the active CP blade to prevent failover or communication
between the CP blades during the replacement.
9. Logged into the active CP, run the following two steps to upload the system
configuration to a specified FTP server. Enter information at the prompts.
a. Enter the configupload -vf command. This command uploads the system
virtual fabric data.
b. Enter the configupload command. This command uploads the system
configuration.
Removing a control processor blade (CP8)
The SAN384B continues to operate while a CP blade is being installed if the
redundant CP blade is active and a failover does not occur. You can prevent
failover by entering the haDisable command.
Attention: Follow ESD precautions (see “ESD precautions” on page xviii) when
handling any blades.
Note: The CP8 blade is compatible only with the SAN384B and SAN786B
products.
To remove a CP blade, do the following:
