HP DC SAN Backbone Director Switch Hardware Reference Guide (5697-2158, August 2012)

b. Enter the haFailover command.
The functioning CP blade becomes the active CP blade.
c. Wait until the status LED on the functioning CP blade is no longer lit.
d. Enter the haShow command from the functioning CP blade (the new active CP blade) to
verify the failover.
This is an example of failing over a CP blade:
Fabric OS (cp1)
cp1 login: admin
Password:
swDir:admin> hashow
Local CP (Slot 7, CP1): Active
Remote CP (Slot 6, CP0): Standby, Healthy
HA enabled, Heartbeat Up, HA State synchronized
swDir:admin> hafailover
Local CP (Slot 7, CP1): Active
Remote CP (Slot 6, CP0): Standby, Healthy
HA enabled, Heartbeat Up, HA State synchronized
Warning: This command is being run on a redundant control
processor(CP) system. If the above status does not indicate
'HA State synchronized', then the CPs are not synchronized
and this operation will cause the active CP to reset. This
will cause disruption to devices attached to both switch 0
and switch 1 and will require that existing Telnet sessions
be restarted. To reboot a single logical switch on this
system, use the switchreboot command while logged in to
that logical switch.
Are you sure you want to fail over to the standby CP [y/n]?
swDir:admin> haShow
Local CP (Slot 7, CP1) : Standby, Healthy
Remote CP (Slot 6, CP0) : Active
HA Enabled, Heartbeat Up, HA State Synchronized
5. Enter the firmwareShow command to view the firmware version of the active CP blade.
6. Enter the haDisable command from the active CP blade to prevent failover or communication
between the CP blades during the replacement.
7. While logged into the active CP, use the configUpload command to upload the DC SAN
Director configuration to a specified FTP server. Enter information when prompted.
This is a sample of backing up the configuration files:
swDir:admin> configUpload
Protocol (scp or ftp) [ftp]: ftp
Server Name or IP Address [host]: 123.456.78.90
User Name [None]: user
File Name [config.txt]: config.txt
Password: xxxxxxxx
