SVC timeout, error HWN099993E

Technote (troubleshooting)


Problem(Abstract)

TPC generates error HWN099993E when monitoring SVC subsystems.

Symptom

TPC unable to monitor SVC.


Cause

SVC microcode issue.

Environment

TPC with early SVC 6.x code.

Diagnosing the problem

Examine the device server logs for timeout exception:

In dmSvcTrace.log:
com.ibm.tpc.disk.common.util.thread.DiskManagerTimeoutException: Execution time exceeded 45000 milliseconds
@(-9223372036854775133;[-9223372036854774558,0,0];-9223372036854774557;DiskManagerThread-5)

Resolving the problem

There are a couple of known issues which can prevent the collection of statistics from early 6.x SVC cluster code.

It is recommended to upgrade to at least code. 6.1.0.8.

IC76264 Incomplete data from onboard statistics collection.

IC75166 Large numbers of GUI connections can lead to host I/O performance degradation.
