sap_swpm: ascs failed install async

[Baboulinet-33]

Hello,

I'm trying to install ASCS on nodes ascs_group and ERS on nodes ers_group - each group has one node here. In the futur, I want to install a pacemaker cluster via the role sap_ha_pacemaker_cluster

My playbook:

- hosts: all
  become: true

  pre_tasks:
    - name: Manage repo
      ansible.builtin.include_tasks: tasks/repo.yml

  roles:
    - role: community.sap_install.sap_general_preconfigure
    - role: community.sap_install.sap_netweaver_preconfigure

- hosts: ascs_group
  become: true
  roles:  
    - role: community.sap_install.sap_install_media_detect
    - role: community.sap_install.sap_swpm

- hosts: ers_group
  become: true
  roles:  
    - role: community.sap_install.sap_install_media_detect
    - role: community.sap_install.sap_swpm

When ansible try to install ascs I get the following error:

TASK [community.sap_install.sap_swpm : SAP SWPM -] *****************************15:15:48
changed: [ascs_node01]

TASK [community.sap_install.sap_swpm : SAP SWPM - Wait for sapinst process to exit, poll every 60 seconds] ***15:15:49

}

But in the same time, the sapinst.log file fills up - and I got the error ( I cleaned the directory before running ansible):

I'm missing a conf ?

Firstly, you are dynamically detecting the installation media using sap_install_media_detect Ansible Role but your Extravars file will override these with the incorrect variable values. It doesn't cause an error but isn't necessary:

# Software
sap_swpm_software_path: /data/bin
sap_swpm_sapcar_path: /data/bin
sap_swpm_swpm_path: /data/bin 

The async Ansible Task (used because SSH connections can otherwise drop while waiting 1-3 hours for SAP SWPM to complete) immediately failing to poll is a new error and difficult to diagnose without access. It's possible SAP SWPM fails within 60 seconds, which might explain.

The actual SAP SWPM halting error is /usr/sap/<<SID>> from a previous run is causing the error. If the directory is clean before running, are you sure the NFS is mounted correctly for /usr/sap/* mount points when creating ASCS/ERS HA pair?

Drop me an email if you want to preview the advanced Playbooks to be released in the coming weeks; it might accelerate your current work.

Some news about the async problem, we don't change anything but today it works once in two.

Without the following var it doesn't work:

# Software
sap_swpm_software_path: /data/bin
sap_swpm_sapcar_path: /data/bin
sap_swpm_swpm_path: /data/bin

Some news here, with a pause between tasks TASK [community.sap_install.sap_swpm : SAP SWPM -] and task TASK [community.sap_install.sap_swpm : SAP SWPM - Wait for sapinst process to exit, poll every 60 seconds] it works
