Servers - Tape securing SCSI connectors may cause hard drive failures
Applicable to: World-Wide
SYMPTOM:
Hard drives may fail or hard drives in a array may be marked DDD.
PROBLEM ISOLATION AIDS:
All of the following must be true for this tip to apply:
- The System is a model 8639 or 8640 that has a strip of tape on the 68-pin SCSI connector at one or both ends of the SCSI cable.
- The tape is touching/covering any portion of the ends of the SCSI cable leads that are exposed on one side of the SCSI cable connector ----- AND/OR ---- the tape is in contact with any conductive surface of a backplane or system board that the end of the SCSI cable is connected to.
FIX:
1- Remove the tape and re-seat the connectors.
2- If the server is to be moved/relocated, check that the SCSI cables are connected securely after the move/relocation of the server.
DETAIL:
A conductive tape was used to help ensure that the SCSI cable connections do not loosen during shipping. In SOME cases, the tape may touch nearby electrical connections or the exposed ends of the SCSI cable leads. It is POSSIBLE that the conductive tape may short some portion of the SCSI Bus or SCSI Bus related circuits of a backplane or system board which may result in the above described "Symptoms". Systems are now manufactured with non-conductive tape.
