4. If the functioning CP blade is performing as the active CP blade, go to step 5. If the faulty CP
blade is performing as the active CP blade, failover the blades:
a. Login to the faulty CP blade as admin, using either a Telnet or a serial console connection.
If you connect successfully to the faulty CP, continue to step 4b.
If you cannot connect to the faulty CP, remove the faulty CP blade for repair as follows:
• Turn the CP blade off and notify the DC04 SAN Director of a hot swap request by sliding
the slider switch in the top ejector down to the off position (see
• Wait until the active CP LED on the functioning CP blade is lit, and then remove the CP
blade.
b. Type haFailover.
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. Type haShow 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. Type firmwareShow to note the firmware version of the active CP blade.
6. Type haDisable from the active CP blade to prevent failover or communication between the CP
blades during the replacement.
