Host details under monitoring in H&W are not populated properly

Issue

The  Hosts section under  Health & Wellness >  Monitoring doesn’t display the Physical drive, logical drive, and adapter details due to an upgrade of the perccli library to the newer version.

Cause

The issue is happening because till 11.7.0.x version the library responsible for collecting data (perccli) was on version “ perccli-007.0318” but 11.7.1.x onwards the version being used is “ perccli-007.1623“ which uses totally different commands to extract physical and logical drive information and output format is also completely changes, hence the information is not available.

Workaround

1. Download the Nwraidutil.py file 
2. SSH to the Admin Server or the node on which you are copying this file.
3. Copy the Nwraidutil.py file to the host where the host details for the node were not displayed in the UI.
4. Stop the collectd service by running the following command: systemctl stop collectd
5. Take a backup of the existing python file located at /usr/lib/collectd/python/nwraidutil.py . In case of any issues, you can roll back.
6.  Replace the file /usr/lib/collectd/python/nwraidutil.py with the new file.
7.  Start the collectd service by running the following command: systemctl start collectd

PS: The hotfix needs to be applied on all the hosts

Resolution

We will have to provide a hotfix where the commands from perccli-007.1623 will be correctly used and parsed.
