Abstract: SERIALRAID ADAPTER: use NT SP4 and 6450 ADAPTER UCODE

SYMPTOM:

MSCS failover does not complete successfully.

PROBLEM ISOLATION AIDS:

•  The system is any of the following machine's:

    IBM Machine Types: 8639, 8640, 8659, 8651, or 8680
    Compaq ProLiant 3000 and 5500 (single, dual CPU models)
    Compaq ProLiant 6500 and 7000 (dual, quad CPU models)
    Hewlett-Packard NetServer LH2 and LXr Pro 8

•  The system is configured with a IBM SerialRAID Adapter, Option kit P/N 09L2084 (7133 FC4013),
   FRU P/N 09L2130: includes asm part number 09L5544 and any future revisions.
•  The IBM SerialRAID Adapter's Firmware level is 6350.
•  The system is configured with Microsoft NT version 4.0 with Service Pack 3 or earlier.
•  The Device Driver for the SerialRAID Adapter is NT drivers kit 1.06.
•  The system's Diagnostics pass.

FIX:

Use NT Service Pack 4 and Adapter Microcode level of 6450 or later.
The latest available level of Adapter Microcode for the IBM Serial RAID adapter for PC Servers
can be obtained and downloaded from the following URL:

http://www.hursley.ibm.com/ ssa/pcserver/

WORKAROUND:

No workaround. Apply latest microcode and NT Service Pack 4 as listed in "FIX", above.

DETAILS:

When the IBM Serial RAID Adapter for PC Servers, part number 09L5544 (and future revisions, if any), is used in a configuration utilizing the Microsoft Cluster Service software (Wolfpack),
a failover timeout problem may be experienced.
The failover operation will not complete and the remaining host will not take control of all resources.

This problem is likely to occur only with adapters which have a microcode level of 6350 and where NT Service Pack 3 is being used.

INFORMATION ON SERVER STABILITY:

•  By SerialRAID adapter, no.
•  By NT 4.0 SP3 & earlier, see SP4 release notes, as decsribed below:
