Cisco ASA Firmware Update on Failover Cluster
First we need to copy the firmware update and the ASDM on the Units. Please note these are not synced unlike the configuration. With savings via ASDM once again on the active to the passive IP and then upload it via browser, alternatively via CLI and tftp:
hostname# copy tftp://10.1.1.1/asa844-1-k8.bin disk0:/asa844-1-k8.bin hostname# copy tftp://10.1.1.1/asdm-649-103.bin disk0:/asdm-649-103.bin
next boot we will use the new firmware:
boot system disk0:/asa844-1-k8.bin asdm image disk0:/asdm-649-103.bin
Don’t forget to save!
Be sure to be on of the active ASA:
ASA# sh failov state State Last Failure Reason Date/Time This host - Primary Active None Other host - Secondary Standby Ready None ====Configuration State=== Sync Done - STANDBY ====Communication State=== Mac set
This host Primary Active.. nice!
Now, we restart the standby unit:
Wait until the replication of the config is done and move the active role in the cluster to the standby unit(new firmware).
sh failover state no failover active
Then we restart the new standby unit(still old firmware), by connect us back on the active unit, and then
Thats all Folks!
