Hi,

I have the same problem with CX4-480 Flare: 04.30.000.5.522.

The Vendor changed 2 times the SPS and the serial cable between SPS and SP.

In this particular case, error Cabling Status Unknown, the failed controller B, the controller of battery A also assume the cache controller B? Ie my cache would not be turned off because the batteries are mirrored? Only there is a risk of data loss if the error existed in dua enclosures SPE SPS?

I used the following solution:

Workaround:

Use the following workaround in order of increasing impact for immediate mitigation to the problem:

1. Pull sense cable inspect for pushed pins, replace if necessary. If not, hold out for at least three seconds then re-insert. Perform the action on the peer SP only if necessary.
2. Reboot the SP on the side that is reporting the error.
3. Reboot the other SP.

The fault has disappeared, but I wonder if my concept cited above is correct? One would also tell me the mode of operation of these SPS?

Note: We no longer deal with EMC because I work in government and the administration does not want to renew the contract for not being with available cash.
