upgrade ASA cluster using CSM

[shisaraf2011]

Hi Im trying to upgrade a cisco ASA cluster using CSM .

Is there a way to do this without any network disruption?

I understand from the clustering documents that upgrading a cluster requires me to first upgrade the slave,disable clustering on the master and then reload the master . However no such options are available on the CSM. Does CSM take care of these steps?

I am using the installation wizard in the Image manager on CSM

thanks!

Hi,

CSM Image Manager will take care of the upgrade on the ASA cluster automatically in a same way as the ASA HA pair.

Refer:-

http://www.cisco.com/c/en/us/td/docs/security/security_management/cisco_security_manager/security_manager/4-8/user/guide/CSMUserGuide/immgt.html#pgfId-137912

Summary:-

    Slave cluster members are first loaded with the new image from the master. Images are copied to all members of a cluster while being connected only to the master. Such propagation through a cluster does not require switchovers of each device to master status and, thereby, minimizes traffic disruption.
    Configuration is changed on the master to add the boot command to load with the new image. The configuration, once changed on the master, automatically gets synced on all the slave units.
    All the slave cluster members reboot with the new image sequentially via the cluster master.
    All the slave cluster members come online and rejoin the cluster.
    The cluster master is then made into a slave (with the next slave member taking over the cluster master role).
    Via the new master, the old master is reloaded with the new image.

This procedure for image update followed by Image Manager ensures minimal switchovers and minimal disruption of traffic.

Hope this helps.

Thanks and Regards,
