6 Troubleshooting

Review the following troubleshooting steps if problems are encountered when following the installation instructions in this document.

Problem: The drive is not appearing online or times out in the Windows Disk Manager with an I/O error.

Solution: Confirm the HP PCIe Workload Accelerator drive and driver have been successfully installed. Check whether the LED status on the adapter board is blinking with an alternating flashing pattern. If this flashing pattern occurs, wait until the LED stops blinking (this can take several minutes), reboot the system, and try again. Review the Windows System Event or Linux message logs for HP PCIe Workload Accelerator drive messages related to this event.

Solution: Check the LED codes.

Problem: Install errors are occurring after an attempt was made to install the driver from the appropriate rpm file.

Solution: Verify the version of RHEL or SLES you are using. The driver supports either RHEL 5.5 and later or SLES 11 and later. Run uname –a to check the kernel version. It should be 2.6.25 or later to install the driver. If your operating system or kernel version is earlier, upgrade to the latest HP-supported Linux operating system release and re-install the driver.

Problem: The HPWAM GUI does not display correctly or does not load at all.

Solution: The HPWAM GUI requires that 64-bit Oracle only JRE version 1.6 update 10 or later be installed on the system before it can be used. Ensure that multiple versions of Java are not running on the system and that the system path is pointing to an Oracle Java version 1.6 update 10 or later. The HPWAM CLI does not require Java. All HPWAM functions are available through the CLI if Java is not pre-installed on the host system.

Problem: A secure erase must be performed on the drive, but HPWAM is prompting for a password. What is the password?

Solution: The password for performing a secure erase on the drive is ffff (lower case).

Problem: The firmware was successfully updated on the HP PCIe Workload Accelerator drive, but HPWAM still shows the previous version.

Solution: Restart (warm boot) the system and run HPWAM again. The updated firmware version should display.

Problem: Performance tests run on the HP PCIe Workload Accelerator are lower than the values specified in the data sheet.

Solution: Follow these steps to optimize the performance of the HP PCIe Workload Accelerator:

1.Verify you are following HP's recommended SSD testing flow when running performance tests on the HP PCIe Workload Accelerator.

2.Verify the Power Limiting setting on the HP PCIe Workload Accelerator is disabled. In the command line, run: rssdm -L -d Power limiting throttles host I/O traffic to keep drive power under the 25W PCIe CEM slot limit. The side effect of this behavior is reduced performance.

3.Make sure the system running the performance tests meets the hardware requirements.

4.Follow the recommendations documented in Micron's How System Settings Impact PCIe SSD Performance white paper.

5.Update the P320h driver and firmware to the version available in the latest support pack on micron.com.

6.Check the HP PCIe Workload Accelerator temperature to verify that thermal limiting is not affecting performance:
