Error while configuring Initial configuration after ASA installation on firepower 1140

[PradeepkumarPalani2405]

Dear Patrons!

We have installed ASA version 9.13.1(10) on Firepower 1140 but during initial configuration on the FX-OS getting the below error,

Firepower-1140# scope fabric-interconnect a
Firepower-1140 /fabric-interconnect # set out-of-band ip x.x.x.x netmask 255.255.255.0 gw x.x.x.x

Firepower-1140 /fabric-interconnect # commit-buffer

 Error: commit-buffer disabled while in appliance mode.

Any thoughts on this?

The possible cause as follows, the deployment was Appliance mode wherein everything has be configured on the ASA CLI itself.

But the mode can be changed to platform mode by providing the below commands,

"ciscoasa(config)# no fxos mode appliance
Mode set to platform mode
WARNING: This command will take effect after the running-config is saved and the system has been rebooted. Command accepted."

But unfortunately the command itself not available on ASA CLI.

Any thoughts?
