Troubleshooting missing subnet whitelist for SpanFS access
NetBackup needs network access to the SpanFS file system for Direct-IO operations. If the required IP subnet isn't added to the SpanFS subnet whitelist, SpanFS rejects the RPC requests, causing backups to fail.
Issue:
When the subnet whitelist is missing or incorrect, backups fail with status 83 and logs show errors such as:
image open failed: error 2060037: access not allowed
Resolution:
To resolve this issue, add the required subnet to the SpanFS whitelist.
iris_cli cluster add-subnet-to-whitelist subnet-ip=<IPv4 address> subnet-mask-ip4=<IPv4 subnet mask>
