PowerFlex 4.X: Deployment Fails "SSL Certificate Problem: Unable To Get Issuer Certificate"

• PFxM Appliance is using a custom-signed SSL certificate
• Trying to deploy new Storage Only HCI nodes
• Trying to expand a current Storage Only HCI Resource Group
• Trying to upgrade a current Storage Only HCI Resource Group

Thin-deployer's deployment.log shows the following:

ERROR [2023-12-06T15:10:47.435192] 56708: service_deployment.rb:1858:in `process_ansible_errors': Error Message: No provider of '+nmon' found.
DEBUG [2023-12-06T15:10:47.435484] 56708: service_deployment.rb:1868:in `process_ansible_errors': errpr_desc = No provider of '+nmon' found.; additional_error_check = false

This error is pointing to the package nmon as not available. It could be any RPM package from the repository.

Thin-deployer's *.out file related to the nodes that are failing shows the following:

" - [|] Error trying to read from 'https://10.1.0.1/httpshare/download/8aaa812487be83780187be8d264c1aad/os/VxFlex4.0.1SLES15.3Repo/dellemc_ism'",

The same issue is seen when using curl from the Storage Only/HCI nodes:

Impact

New deployments and expansions or upgrades of Resource Groups are not successful.

When you replace the default SSL ingress certificate with a custom SSL certificate signed by an external CA, the nodes do not receive a copy of the new CA certificate. The operating system uses this CA certificate to verify and validate signed SSL certificates. If the operating system does not trust the new CA certificate, the repository download is rejected.

For a SLES-based Storage Only HCI node:

1. Copy the Entire root CA Chain certificate (PEM format) to 

   /etc/pki/trust/anchors/

2. Run command: 

   update-ca-certificates

   
    

For a RHEL-based Storage Only HCI node:

1. Copy the Entire root CA Chain certificate (PEM format) to 

   /etc/pki/ca-trust/source/anchors/

2. Run command:

    update-ca-trust
