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.

•  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 PC Server 704, 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:

•  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

FIX:

•  This problem will be fixed in next BIOS/Firmware release.
•  The target date for the release is scheduled for: May/June, 1999.
•  It will be available from the following URL:

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.
