PowerStore: Pre-Upgrade Health Check (PUHC) to Identify duplicate NTP Entries

Summary: This health check ensures that no duplicate NTP server IP addresses exist and verifies internal consistency. The check applies to upgrade paths from 3.x/4.0.x/4.1.0.0 → 4.1.x/4.2.x, but not for 4.3.x or higher or systems already at 4.1.0.1. ...

Symptoms

PowerStore pre upgrade health check (PUHC) fails with error: cyc_ntp_addresses_duplication_check_error 

job details page

Without this health check, customers risk encountering upgrade failures due to duplicate NTP server IP configurations. PowerStore OS remains in a partially upgraded state, requiring manual intervention and rollback or recovery steps. This can lead to extended downtime and delayed upgrade schedules, impacting service availability.  

Cause

The failure is triggered by duplicate NTP server IP addresses configured in the system, causing mismatched UUID updates between System Manager (SYM) and internal management database.

This condition typically arises when multiple identical NTP servers are added manually during Initial Installation (ICW) or by PSTCLI before initiating the upgrade.

Resolution

Do not proceed with the NDU until the issue is resolved.

Remove duplicate NTP server entries before retrying the upgrade. Ensure that each NTP server has a unique IP address.

Validate the configuration using PSTCLI or user interface to confirm consistency between SYM and management database.
