Installing the HP PCIe Workload Accelerator Software
5 Verifying the Installation
To verify that the installation was successful:
1. In the operating system, verify that the drive appears as a recognized device and that the
driver has been loaded. Refer to the sections in“Installing the HP PCIe Workload Accelerator
Software” (page 11) for a description of the specific steps used to verify this.
2. Verify that the drive is online and ready to be used.
a. In Windows:
1) Open the Disk Management tool (refer to the documentation for your specific version
of Windows). The newly installed drive should display.
2) A dialog box may appear that prompts you to initialize the master boot record (MBR)
for the drive. Select OK and continue. The drive should appear as “Online” with
“Basic” as the format status. If the option to initialize the MBR does not appear,
right-click the drive number in the Disk Management tool and select Initialize Drive
from the pop-up menu. Once this operation completes, the drive should appear as
Online with Basic as the format status.
b.
In Linux:
1) After the system boots to the desktop, open a terminal window.
2) Run modinfo mtip32xx. The version and module information displays if the driver is
installed. Otherwise, follow the installation steps in “Installing the HP PCIe Workload
Accelerator Support Pack on a Linux System” (page 12).
3) Run fdisk – l | grep rssd*. The HP PCIe Workload Accelerator should appear as
/dev/rssd<x> device. <x> is the drive letter, which is typically “a” for one drive.
The letter increments for each additional drive in the system.
3.
Run HPWAM (either the GUI or CLI) and check the status of the drive.
a. If using the GUI, verify that HPWAM loads and that the drive information is shown in the
SSD Info section.
b. If using the CLI, run rssdm –L and rssdm –L –d and verify that the drive information firmware
and status indicate that the drive is present and functional.
4.
The drive is installed and is ready for testing.

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:
16
Troubleshooting
a.
b.
c.
Run rssdm -S.
Check SMART attribute 194 (enclosure temperature) and compare value to the temp
throttle threshold in C.
If the enclosure temperature is greater than or equal to the threshold temperature,
performance decreases.
Problem: How can the Power Limiting setting be enabled on the HP PCIe Workload Accelerator?
Solution: If your system is running a support pack release later than B126.01, the power limiting
setting is disabled by default.
To enable the power limiting setting, use the RSSDM command line interface (CLI):
1. In the command line, type the following command where <Drive_id> is the ID number of the
HP PCIe Workload Accelerator, which can be found by running rssdm -L. rssdm –M –p 1
–n<Drive_id>
2. Power-cycle the system.
3. Verify the setting change by running the following command: rssdm –L –d
Problem: When disabling an ATA channel using Windows Device Manager in Windows Server
2008, the Microsoft Management Console (MMC) stops responding, the computer will not shut
down, and a "Stop 0x0000009F" message appears after 10 minutes.
Solution: This is an issue specific to Microsoft Windows and is not related to the HP PCIe Workload
Accelerator driver. The issue has been corrected for Windows Server 2008 as a hot fix; check the
Microsoft web site for details.
Problem: The Percentage Lifetime Used or Write Protect Progress SMART parameter report shows
100% for the HP PCIe Workload Accelerator.
Solution: These reports both indicate the HP PCIe Workload Accelerator is in the write protect
state. In this state, no additional data can be written to the drive (the drive is in a read-only mode).
All data on the drive is preserved and can be read or backed up. Back up the data on the drive.
After the data is backed up, it is highly recommended to replace the drive and refrain from using
it.
Problem: What are the behavior characteristics of a HP PCIe Workload Accelerator SSD that becomes
too hot? Can the drive still be used? What steps can be taken to reduce the SSD's temperature?
Solution: Two mechanisms control temperature and prevent damage to the drive: thermal limiting
and thermal shutdown. Thermal limiting is a dynamic mechanism that monitors temperature in the
background while host I/O traffic is being processed on the drive. If the SSD temperature exceeds
a preset limit, host traffic will be progressively reduced until the temperature goes below the
threshold point. Once below this threshold point, host traffic will be unthrottled and full performance
restored. If the temperature continues to increase above the threshold point, host IOPS will continue
to be throttled until the drive is in the thermal shutdown state. In this state, the drive will be disabled
from all I/O traffic but will continue to be recognized by the system.
To verify the state:
•
In Linux: run the rssdm –L command or check the Linux message logs (the drive will be reported
to be in the thermal shutdown state).
•
In Windows: check the Event/Error log and verify a thermal shutdown event occurred.
To recover from a thermal shutdown state:
1. Shut down the system.
2. Remove the HP PCIe Workload Accelerator from the system and allow it to cool.
3. If the HP PCIe Workload Accelerator is running firmware older than version 1.45, upgrade
the firmware to the latest available support pack release.
4. Check the SSD placement in the system motherboard and make sure there is sufficient airflow
around the SSD, as specified in the data sheet. If possible, place the SSD in a PCIe slot that
provides unobstructed airflow.
17
5.
6.
Power the system on.
Run the rssdm –L command to verify the SSD temperature. If the temperature remains below
the thermal threshold limit, the SSD is ready for use at full performance. If the temperature
exceeds the thermal threshold limit, the SSD can still be used but performance will be reduced
because of the thermal limiting effect.
Problem: The Flash Translation Layer (FTL) rebuild status in the Windows Event Log and Real
SSDManager does not steadily increase.
Solution: This is expected behavior because of the firmware algorithm that reports the progress of
this rebuild. Whenever a drive experiences a nonstandard or unexpected power-down event, the
drive needs to rebuild its internal LBA-to-NAND address lookup (FTL) tables to prevent data loss.
The drive does not respond to host commands during this rebuild. Because this process takes some
time to complete, both the Windows Event Log and RealSSD Manager record the percentage
complete until the drive is online again. In the RealSSD Manager, the progress of the rebuild is
reported in both the CLI and GUI.
Problem: For HP PCIe Workload Accelerator SSDs with a driver from Support Pack version 128.07
or earlier, when the SSD enters write protect mode at end of life (EOL), the SSD will no longer be
functional.
Solution: Before the SSD reaches EOL, update the driver to a version in Support Pack 131.02 or
later. To monitor EOL, poll SMART attributes 202 and 242. Note: When the SSD reaches write
protect mode, the SSD will continue to have read access in the system, and therefore, data can
continue to be backed up.
