Node: node01
Resource: Shelf 4.11
Severity: Major
Indication Time: Tue Jan 30 21:00:54 2024
Suppress: false
Acknowledge: false
Probable Cause: Controller JC8FAS02-03 has only a single-path configuration to disk shelf 4.11. This might occur when the controller does not have dual-path
configuration to stack 4, a SAS HBA port on the controller connected to the disk shelf is disabled, or shelf-to-shelf cabling is incorrect.
- EMS logs:

- No fault LEDs are light on the IOM module.
- Check the shelf path by running "
system node run -node {nodename|local} -command sasadmin expander_map" command from the console, or examining "SAS-EXPANDER-MAP" in ASUP.
