HP NetRAID-4M Configuration and Upgrade Guide (Release 5)

Chapter 9 Issues and Problem Resolution

Workaround: The issue has been fixed by changing Drive_Config to remove

entries for product in mscsi file added by the OS during system boot and replace with

entries for all supported product devices.

40 SCSI probe taking too long failing HCTs

Problem: Microsoft HCT (Hardware Compatibility Test) sometimes reports an

isalive failure caused by SCSI bus probe taking too long. The HCT test involves

multiple reboots and blue screens of one of the systems for 24 hours. This means that

the timing has to be well synchronized for the test to pass. One of the issues that

surfaced was the Probe command spends too much time trying to communicate with

all the SCSI devices after a reboot. This extended period of time caused the HCT test

to fail.

Frequency of Occurrence: The HCT test is run by OEMs to get the logo

certification.

Impact to Customer: None. End users do not run Phase 5 HCT tests in their

working environments.

Resolution: Issue listed for information only. No action required.

41 Unexpected crash using NetRAID-4M in Marathon subsystem

Problem: When a NetRAID-4M is installed in a Marathon subsystem when FAST

is installed the system may crash unexpectedly. The problem occurs because the

underlying disk subsystem does not respond to a private I/O control code that the

management driver component of FAST (in Windows 2000) sends down the device

stack. The management driver attempts to call the debugger when this I/O control

fails. In a release version of the driver the system does not properly handle the

breakpoint exception resulting in a system crash.

Frequency of Occurrence: Often, whenever the Marathon configuration is utilized.

Impact to Customer: Serious. The access to the data is disabled.

Workaround: Fix consists of commenting out call to DbgBreakPoint() in the

management driver’s AfaErrorPrint() routine. Eliminating the breakpoint is safe

because everything that calls the error print routine assumes that execution will

return if no debugger is attached.
