Servers - 9086001, Sharing IRQs may cause unpredictable results
Applicable to: World-Wide
Source: RETAIN tip H165698
Abstract: 9086001 - SHARING IRQS MAY CAUSE UNPREDICTABLE RESULTS
SYMPTOM:
When installing a Netfinity ESCON Adapter (p/n9086001), unpredictable results may occur if the adapter shares IRQs.
Possible problems could be as follows:
- Systems Network Architecture (SNA) addresses would not come online to the host unless Communication Server for NT (CS/NT) was up with those addresses configured in a link.
- With CS/NT up, the addresses would come online to the host, but a session could not be established to CS/NT. The host Physical Unit's (PU's) stayed in preqc status, and the CS/NT link did not activate. Eventually, CS/NT operations panel showed a big X mark through the ESCON Data Link Control (DLC). These are only examples of possible problems. Others may occur.
PROBLEM ISOLATION AIDS:
- The system is one of the following IBM Netfinity servers that supports the Netfinity ESCON Adapter:
a Netfinity 5000 server, Type 8659, any Model.
a Netfinity 5500 server, Type 8660, any Model.
a Netfinity 5500-M10 server, Type 8661, any Model.
a Netfinity 7000 server, Type 8651, any Model.
a Netfinity 7000-M10 server, Type 8680, any Model.
- The system is configured with a Netfinity ESCON Adapter p/n9086001.
NOTE - The current list of products that have been tested with current models of IBM Netfinity and PC Servers is available at the following URL:

Click on "Host Attach/Mainframe Adapters".
FIX:
Insure that the Netfinity ESCON Adapter has its own dedicated IRQ. If 2 adapters are installed, make sure both have their own dedicated IRQ.
Verify Resources are not shared.
DETAILS:
The Netfinity ESCON Adapter will not share resources.
