Servers - Resource conflicts with shared IRQs running OS/2 Warp Server

Applicable to: World-Wide

Source: Retain tip H166497

Abstract: Resource conflicts with shared IRQs running OS/2 Warp Server.

Symptom:
Resource conflicts may result in (and are not limited to) any of the following symptoms:

• OS/2 Traps
• OS/2 fails to install
• Drivers fail loading
• Server fails to service clients under high LAN and/or hard drive activity.

Problem isolation aids:

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):

• Onboard ServeRAID
• a PC ServeRAID SCSI Adapter, Option p/n70G8489
• a ServeRAID II Ultra SCSI Adapter, Option p/n76H3584
• a Netfinity ServeRAID-3H Ultra2 SCSI Adapter, Option p/n01K7207
• a Netfinity ServeRAID-3L Ultra2 SCSI Adapter, Option p/n01K7364

NOS affected:

• OS/2 version 4.0 with any level of fix-pack

Fix:
The server BIOS may auto assign interrupts to adapters. Manually configure the interrupts such that interrupts are NOT shared between the ServeRAID adapter (or on-board ServeRAID) and LAN adapters with OS/2 Warp Server SMP v4.0.
