H166102: REBUILDING MULTI DDD DRIVES ACROSS MORE THAN ONE ARRAY TEXT: REBUILDING MULTI DDD DRIVES ACROSS MORE THAN ONE ARRAY SYMPTOM: - Multiple DDD drives located across multiple arrays. - Hot Swap Rebuild is enabled. - One (1) HDD is located at Channel 1, Drive ID 0. PROBLEM ISOLATION AIDS: - The system is any of the following IBM servers: a Netfinity 7000-M10 server, Type 8680, any Model. a Netfinity 7000 server, Type 8651, any Model. a Netfinity 5500-M10 server, Type 8661, any Model. a Netfinity 5500 server, Type 8660, any Model. a Netfinity 5000 server, Type 8659, any Model. a Netfinity 3500 server, Type 8644, any Model. a Netfinity 3000 server, Type 8476, any Model. a Netfinity 704 server, Type 8650, any Model. a PC Server 720, Type 8642, any Model. a PC Server 520, Type 8641, any Model. a PC Server 330, Type 8640, any Model. a PC Server 325, Type 8639, any Model. a PC Server 320, Type 8640, any Model. a PC Server 315, Type 8638, any Model. a PC Server 310, Type 8639, any Model. - The system is configured with one (1) or more of the following: Onboard ServeRAID PC ServeRAID SCSI Adapter, Option p/n70G8489 ServeRAID II Ultra SCSI Adapter, Option p/n76H3584 Netfinity ServeRAID-3H Ultra2 SCSI Adapter, Option p/n01K7207 Netfinity ServeRAID-3L Ultra2 SCSI Adapter, Option p/n01K7364 - The system has multiple DDD drives. - The system has multiple arrays. - The system has Hot Swap Rebuild enabled. - The system has one of the DDD drives located at Channel 1, Drive ID 0. - All Firmware levels prior to and including 3.11 for the ServeRAID III, 2.88 for the ServeRAID II and onboard controllers, and 2.25 for the ServeRAID I. - The system's Diagnostics Pass WORKAROUND: In order to avoid this problem, do NOT replace the Channel 1, Drive ID 0 DDD drive first. Rebuild the other drive (wherever it might be), and upon its successful conclusion rebuild the DDD drive at Channel 1, Drive ID 0. DETAILS: The default Hot Swap Rebuild program will look to rebuild to Channel 1, Drive ID 0. If multiple logical drives are in a Critical state, then they all will attempt to rebuild to the Channel 1, Drive ID 0 at the same time. DATE: March 22, 1999
