H133326 - ECA003, PREVENT MULTIPLE DDD SCSI DRIVES IN SERVER PURPOSE: This ECA provides for installation of a Pin Converter on some SCSI 1GB, 2GB, and 4GB Hot-Swap fixed disks in affected IBM PC Server systems. The Pin Converter is a small cable connector interposer, which attaches between the fixed disk SCSI-ID pins and the SCSI-ID cable. Important: Install the interposers on hard drives mounted in TYPE 2 TRAYS FRU p/n06H3956 ONLY (This tray has only the light pipe LED). Do NOT install the interposers on drives mounted in TYPE 3 TRAYS FRU P/N06H8631 (This tray has an amber LED, a green LED, and a power button in addition to the light pipe LED). If using TYPE 2 TRAYS without the interposers installed, customers may experience MULTIPLE fixed disks appearing Defunct (DDD) when actually only ONE(1) drive has failed. This symptom is related to the type of drives installed, as described below. In the event of a fixed disk failure, the Pin Converter prevents other drives attached to the same backplane from incorrectly appearing Defunct (DDD). This ECA may be installed at any time on eligible systems; there is no fix-on-fail requirement. See Record H131887 for recovery instructions when multiple disks are DDD. This ECA expires 4/30/97.

PHYSICAL CHECK: Systems eligible for this ECA are IBM PC Servers 8640 (with Hot-Swap Bay Assemblies installed), 8641, and 8642, WHICH HAVE ANY OF THE FOLLOWING FIXED DISKS INSTALLED: - 1GB FRU p/n 06H8560 - 2GB FRU p/n 06H8561 - 4GB FRU p/n 06H8562 The affected drives are known to have been installed in the above system models, however not all of these systems will have the affected fixed disks. The simplest way to inspect for eligible drives is to remove the front system cover, exposing the front of the fixed disks. Eligible drives are silver. There may also be black drives in the system, which do not require this ECA. Systems may have either type of drive installed, or a combination of both. The Pin Converter should be installed only on the drives listed above in both RAID and non-RAID systems; however, if placed on the correct SCSI-ID pins of another type of SCSI hard drive, no damage will occur. Install the interposers on hard drives mounted in TYPE 2 TRAYS FRU p/n06H3956 ONLY (This tray has only the light pipe LED). Do NOT install the interposers on drives mounted in TYPE 3 TRAYS FRU P/N06H8631 (This tray has an amber LED, a green LED, and a power button in addition to the light pipe LED). PREREQUISITES: NONE COMPANION: NONE CONCURRENT: NONE DETAIL: To obtain Pin Converters, order the IBM PC Server Pin Converter Kit, FRU p/n75H8103, which consists of six Pin Converter connectors and installation instructions. Without the Pin Converter, the SCSI-ID cable plugs into five of the six pairs of SCSI-ID pins on the drive. The Pin Converter attaches to the cable, and then plugs into all six pairs of SCSI-ID pins on the fixed disk. You can install the Pin Converter to the hot-swap drive while the server is powered-on. However, the SCSI-ID pins are located behind the handle on the front of the drive, limiting physical access to the pins. You might find this procedure easier if you power-off the server and remove the drive. New systems are shipped with a Pin Converter on applicable drives. When replacing a fixed disk that has the Pin Converter installed, transfer the Pin Converter to the new FRU drive. NOTES: This ECA will expire 4/30/97. IBM/TSS CEs should record all time and parts to Service Code 33, ECA003, Other Office 990. November 19, 1996
