Recording critical DC SAN Director information
Back up the DC SAN Director configuration before you replace a CP blade. For more information,
see the Fabric OS Administrator's Guide.
To record critical DC SAN Director information:
1. Log in to the functioning CP blade as admin, using either a Telnet or a serial console connection.
2. Enter the haShow command 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, see the Fabric OS Administrator's Guide
4. If the functioning CP blade is performing as the active CP blade, proceed to step 5. If the
faulty CP blade is performing as the active CP blade, fail over the blades:
a. Log in 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 DC SAN Director of a hot swap request by
sliding the slider switch in the top ejector down to the off position (see Figure 36 (page
70)).
• Wait until the active CP LED on the functioning CP blade is lit, and then remove the
CP blade.
