Abstract: EXP10 / EXP15: RED DRIVE LIGHTS TURNED ON

TEXT:

Red Drive Lights in EXP10 and EXP15 Turned On

SYMPTOMS:

After a Failover in a Microsoft Cluster Server, the Red Drive Lights in IBM Netfinity EXP10 or IBM Netfinity EXP15 storage expansion units may turn on for a drive that is in the Online state.
There is no functional problem. If it does occur, the red lights will turn off within an hour.

•  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-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 1000 server, Type 8477, any Model.
          a PC Server 720, Type 8642, any Model.
          a PC Server 704, Type 8650, 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 the following option(s):

   (Behavior may occur when any of the listed controllers are connected to one of the listed storage units.)

    Controllers:

•  Onboard ServeRAID
•  ServeRAID II Ultra SCSI Adapter, Option P/N 76H3584
•  Netfinity ServeRAID-3H Ultra2 SCSI Adapter, Option P/N 01K7207.

Storage Units:

•  IBM Netfinity EXP10 (M/T 3520-1RU)
•  IBM Netfinity EXP15 (M/T 3520-2RU)

•  The ServeRAID Firmware for the ServeRAID II and ServeRAID 3H are affected.
•  The Firmware levels affected are:

    3.50.22 for ServeRAID 3H adapters
    2.88.10 for ServeRAID II adapters

•  The system's Diagnostics Pass.
•  NOS affected:

    Microsoft Cluster Server Software, any version, at any patch level

FIX:

There is no functional problem. The Red lights will turn off within an hour.

This behavior is very intermittent. Changes have been made in the current code release 3.50.22
and 2.88.10 to minimize this event from occurring, but there is a small chance that this may be seen.
