When an ME412, ME424 or ME484 JBOD enclosure is first attached to ME50xx, the enclosure management processor (EMP) firmware is updated. When the backend SAS cables are either not cabled or cabled incorrectly, the application of the EMP firmware update fails.
The message also occurs if an administrator attempts to connect an expansion enclosure to an ME5 series enclosure supplied with a single controller module. Connecting an expansion enclosure to the ME series requires dual controller modules. Contact Dell sales to purchase another controller module.
Steps to correct:
- Shut down both storage controllers on PowerVault ME5 enclosure 0
- Click Maintenance, then Hardware in the GUI
- Under the Actions dropdown menu for enclosure 0, select Restart/Shutdown System
- Select "Shutdown SC" and check both Controller A and Controller B
- Select Apply
- Power off all enclosures.
- Correct the backend SAS cabling.
- Power on the JBOD enclosures first.
- Power on the PowerVault ME5 enclosure.
- Wait a few minutes and check that the EMP firmware has been updated
How should the attached JBOD enclosures be cabled?
