Disk enclosure IDs not displayed

Hey!

NOTE:

The following enclosure ID is used as an example: DAEXYZ. DAE indicates a disk enclosure, X indicates its cabinet ID, Y indicates its loop ID and Z indicates its position in the loop.

To ensure performance and reliability, the Dorado V3 series allows two SAS ports to be consecutively cascaded to the same disk enclosure (that is, a disk enclosure has two loops). Therefore:

In the case of Dorado5000 V3 that adopts the disk and controller integration, the second digits of its enclosure IDs are odd numbers. Since loop 0 is occupied by the controller enclosure, the disk enclosure IDs start from DAE010 and then DAE030, DAE050, and alike.

In the case of Dorado6000 V3 that adopts the disk and controller separation, the second digits of its enclosure IDs are even numbers. The disk enclosure IDs start from DAE000 and then DAE020, DAE040 and the like.

Dear Axe,
If the ID of a disk enclosure is not displayed after the disk enclosure is powered on properly, the possible cause is that one power module in the disk enclosure is faulty. To resolve this problem, replace the faulty power module. For details, see "Power Module Failure" and "Replacing a Power Module" in Troubleshooting.
It's my pleasure to help you.

Hello!
Did you mean LED display at the front of the enclosure or ID in the web interface?
