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

Chapter 9 Issues and Problem Resolution
54
Problem: One of the new features that was introduced in the latest code release was
a Performance Enhancements for Windows 2000 Miniport driver. This feature
allows a user to turn this option on and gain higher performance under Windows
2000. Since the Performance Enhancement disables some functionality, it is
recommended during Benchmarking tests only. This feature can cause a blue screen
when enabled.
Impact to Customer: Minimal, it occurred only when the option was enabled. It did
not have any impact during normal operation. The performance testing could not be
done.
Frequency of Occurrence: Rare. Only when benchmark testing was required to
run.
Workaround: Found problem related to multiprocessor systems where resources
were being overwritten. The routines were not MP compliant. The issue has been
fixed.
The Performance Enable feature is enabled with a command using CLI. The CLI
lives in the following directory: Drive letter:\Program Files\Hpraid\Hpn\ .
To start the utility user needs to type Afacli Advanced in that directory. This will
bring the CLI prompt with Advanced functions enabled. To enable/disable the
benchmark performance option for the controller, use the Controller Set commands.
The default state is off or /enable=false.
Sample: HPN0> controller set benchmark /enable=true to enable it or /enable=false
to disable it.
This is not a persistent command; the setting will reset to default after reboot.
39 Drive_Config adding incorrect entries in MSCSI file
Problem: The Drive_Config utility is the Open Server script that automates the
MAKDEV process, eliminating the need to reboot after each device is created. This
bug was caused by a wrong entry in the MSCSI configuration file. As the effect, the
system returned error message: Warning duplicate entries in MSCSIHBA 1 0 0.
As a result the system will not fdisk (or divvy) the c1t0d0 or c1t1d0 containers.
Frequency of Occurrence: During new installation only. The Drive_Config utility
can be run only once.
Impact to Customer: Minimal, there is no data so there was no data loss. It forced
the user to use MAKEDEV commands to create the devices.
