Servers - Multi-ServeRAID: Miscellaneous events occur in the event log

Applicable to: World-Wide

Source: RETAIN tip H166172

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.

Note: The Netfinity ServerProven Compatibility web page is at the following URL:
http://www.pc.ibm.com/us/compat/

The system is configured any combination of 2 of the following type of ServeRAID Adapters:

• ServeRAID Adapter FRU p/n06H9334 (Option p/n70G8489)
• ServeRAID Adapter FRU p/n76H6875 (Option p/n70G8489)
• ServeRAID II Adapter FRU p/n76H3587 (Option p/n76H3584)
• ServeRAID-3H Adapter FRU p/n01K7396 (Option p/n01K7207)
• ServeRAID-3L Adapter FRU p/n01K7352 (Option p/n01K7364)

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:

• Novell NetWare version 4.2 w/ IWSP6 applied.

Fix:
This problem will be fixed in next BIOS/Firmware release.

It will be available from the following URL: http://www.pc.ibm.com/searchfiles.html Search on "ServeRAID Firmware".

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.

Trademarks:
Other company, product and service names may be the trademarks or service marks of others.
