Clariion CX4-120 Chassis with boot drives is not “enclosure 0”.

Jump to solution

Hello All,

      I have this problem, the customer was used DAE with boot disk on second storage to migrate some data and address that to enclosure 1, after that they back with DAE to original system on enclosure 0, but now the SPA and SPB won´t boot. Acessing the POST Diag Menu and using DDBS Service sub-menu, checking the Drive Slot ID Check   , they show all drives at wrong slot. The question is, how to change disks "WRONG" to "CORRECT" slot ? all the disks are on the original position and I can access the Clarrion Utility Partition.

Checking LOOP 0

ERRORS found:

    SLOT 0 (Encl 0, Slot 0): Contains disk from LOOP 0 (Encl 1, Slot 0)

    SLOT 1 (Encl 0, Slot 1): Contains disk from LOOP 0 (Encl 1, Slot 1)

    SLOT 2 (Encl 0, Slot 2): Contains disk from LOOP 0 (Encl 1, Slot 2)

    SLOT 3 (Encl 0, Slot 3): Contains disk from LOOP 0 (Encl 1, Slot 3)

    SLOT 4 (Encl 0, Slot 4): Contains disk from LOOP 0 (Encl 1, Slot 4)

    SLOT 7 (Encl 0, Slot 7): Contains disk from LOOP 0 (Encl 1, Slot 7)

    SLOT 8 (Encl 0, Slot 8): Contains disk from LOOP 0 (Encl 1, Slot 😎

    SLOT 9 (Encl 0, Slot 9): Contains disk from LOOP 0 (Encl 1, Slot 9)

    SLOT 10 (Encl 0, Slot 10): Contains disk from LOOP 0 (Encl 1, Slot 10)

    SLOT 11 (Encl 0, Slot 11): Contains disk from LOOP 0 (Encl 1, Slot 11)

    SLOT 12 (Encl 0, Slot 12): Contains disk from LOOP 0 (Encl 1, Slot 12)

    SLOT 13 (Encl 0, Slot 13): Contains disk from LOOP 0 (Encl 1, Slot 13)

    SLOT 14 (Encl 0, Slot 14): Contains disk from LOOP 0 (Encl 1, Slot 14)

Summary:

    Total Disks in the Correct Slots: 0

    Total Disks in the WRONG Slots: 15

    Total Slots Checked: 15

It´s not recommended, but works.

I took the disks back to the second machine, then change the drives signatures, how ? swaping the vault disk one by one, and wait the rebuild, the vault disks must not have any luns for this. After that, return the disk to the "bad" storage, enter on utility partition and re-image the disks, the array back alive.

Thanks for the help.

Did the disks in the DAE get moved to a different DAE? Or did the DAE get moved to a different array? Was there physical movement of the disks or DAE?

Hello Glen,

    DAE was moved to different array, the disks were on the same DAE/Position no movement on they.

Thanks.

I would guess that the attachment of the DAE to the other array changed something on the disks as to identification and when moved back, they would no longer be accessible.

You will need to open a service request with EMC - but I doubt that much can be done to fix this.

The drive signatures would be invalid because they were moved to a different array. You will need probably need to re-initialize the array. Please open a support case and mark this question answered please.

Thanks.
