VM-15: Can the P320h/P420m drive be installed on an AMD-based CPU and chipset
platform?
The P320h/P420m drive can be installed on an AMD-based system using an ESX version
prior to ESX 5.5i.
On systems using ESX5.5i and later, the Micron driver is not able to initialize the drive in
the kernel, resulting in the drive not appearing as a device node in the /dev/disks list.
To work around this issue, it is recommended to use an Intel CPU and chipset platform
(all versions of ESX are supported on these platforms), or downgrade the kernel version
to ESX 5.0 or 5.1i.
RealSSD Manager
RSSDM-1: The RSSDM GUI does not display correctly or does not load
For support pack versions earlier than 138, the RSSDM 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 RSSDM CLI does
not require Java. All RSSDM functions are available through the CLI if Java is not pre-
installed on the host system.
RSSDM-2: The firmware was successfully updated on the drive, but RSSDM still shows
the previous version
Restart (warm boot) the system and run RSSDM again. The updated firmware version
should display correctly.
RSSDM-3: The Flash Translation Layer (FTL) rebuild status in the RealSSD Manager
(RSSDM) does not steadily increase and may decrease
The firmware rebuild percentage reported by RSSDM during the FTL rebuild process
may increase or decrease. This is expected behavior because of the firmware algorithm
that reports the progress of the FTL rebuild (the rebuild percentage is just an estimate of
completion of the rebuild progress). Whenever a drive experiences a nonstandard or
unexpected power-down event, the drive needs to rebuild its internal LBA-to-NAND ad-
dress lookup (FTL) tables to prevent data loss. The drive does not respond to host com-
mands during this rebuild. Because this process takes some time to complete, RSSDM
records the percentage complete until the drive is online again. The progress of the re-
build is reported in both the RSSDM CLI and GUI.
RSSDM-4: System recognizes the drive, but the drive does not appear in RSSDM
The system detects the drive (in Windows Disk Manager/Device Manager or in Linux
using
fdisk -l
); however, in the RSSDM GUI agent or command line, the following error
message displays: "You must run the Agent as a privileged user with admin rights in or-
der to issue the required API command." To correct this issue:
In Linux: Either log in as a root user with root privileges or use '
sudo rssdm -L
' to run
the CLI or '
sudo RealSSDManagerClient.run
' to launch the GUI agent. You will need to
run RSSDM in /opt/MicronTechnology/RealSSDManager if you have not modified your
shell path to include this directory.
