Non-Volatile Storage Health Monitoring

Version 33.6.1 adds health monitoring capabilities for non-volatile (flash) storage on Summit ARM platforms to proactively detect potential storage issues.

Enhancement: The system automatically monitors the health of non-volatile NAND flash memory and logs diagnostic information based on configurable reporting intervals. Health metrics include erase counters and block counts (bad, reserved, available, and total blocks), enabling proactive identification of storage degradation before it impacts switch operation.

Key Capabilities:

• Automatic health monitoring enabled by default on all supported platforms
• Configurable reporting intervals: normal (24-hour) or frequent (1-hour)
• Smart logging that reports only when values require Technical Support investigation (normal mode)
• On-demand health status display showing current flash metrics
• Configuration persists across reboots

New CLI Commands

Display current health status:

show switch non-volatile-storage health-check

Sample output:

Poll period mode: normal
Erase counter:       134
Block counts:
 Bad:                  6
 Reserved:            74
 Available:          969
 Total:             4090

Configure health check reporting interval:

configure switch non-volatile-storage health-check-reporting [normal | frequent]

Where:

• normal - Check on 24-hour period and log messages only if values should be investigated by Technical Support (default)
• frequent - Check on 1-hour period and always log values even when operation is nominal
