Abstract: MULTI-SERVERAID: MISCELLANEOUS EVENTS OCCUR IN THE EVENT LOG

SYMPTOM:

Large number of soft and miscellaneous events occur in the ServeRAID soft event log and device event table.

PROBLEM ISOLATION AIDS:

•  The system is any of the following IBM servers that support any one of the ServeRAID Adapters:

       a Netfinity 7000-M10 server, Type 8680, any Model.
       a Netfinity 7000 server, Type 8651, any Model.
       a Netfinity 5500-M20 server, Type 8662, 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 any combination of 2 of the following type of ServeRAID Adapters:

      ServeRAID Adapter FRU P/N 06H9334 (Option P/N 70G8489)
      ServeRAID Adapter FRU P/N 76H6875 (Option P/N 70G8489)
      ServeRAID II Adapter FRU P/N 76H3587 (Option P/N 76H3584)
      ServeRAID-3H Adapter FRU P/N 01K7396 (Option P/N 01K7207)
      ServeRAID-3L Adapter FRU P/N 01K7352 (Option P/N 01K7364)

•  The system is configured with ServeRAID Administration Utility (any version) with Logical Drive Migration (LDM)  running and logical drive in critical state (1 DDD drive).
•  All firmware versions are affected for the ServeRAID Adapter.
•  NOS affected:

FIX:

•  This problem will be fixed in next BIOS/Firmware release.
•  It will be available from the following URL:

WORKAROUND:

•  Do not run LDM with a DDD drive.
•  Reduce the amount of network activity during LDM.

DETAILS:

This problem may occur when the system's cache is highly utilized, a logical drive is in critical state (1 DDD drive) and 2 types of ServeRAID Adapters are installed.
This problem has only been able to be replicated in development test when a drive goes DDD during an "add to free array space" LDM operation in NetWare v4.2 with IWSP6, a large amount of network activity, and two types of ServeRAID adapters installed in the system.

Note: It may occur with other operating systems if the conditions regarding highly utilized cache with a critical logical drive are met, but development has not been able to replicate in any other operating system environment besides NetWare.
