When patch is installed on ISE distributed deployment from Primary PAN GUI, patch installation gets stuck at "Installation in progress" as can be seen from (Administration -> System -> Maintenance -> Patch Management -> this patch version -> Show Node Status). This stuck ISE node has: - Application service is not running - Copying and installing patch files is not completed properly for all files, then patch installation fails without rollback or start of services.
ISE distributed deployment Patch is installed from GUI of Primary PAN
Access this stuck ISE node, then install patch manually from CLI. After successful patch installation on this stuck ISE node from CLI and application service is running normally, Primary PAN will detect that patch installation is successful on this ISE node, and moves to next ISE node in sequence of deployment to install the patch on it.
