Finding a Physical Disk
For RDR virtual disks, the detail pane presents information in the following format:The
Harddisk0-LUN1-PLEX2 (Basic) 11/40/1 (DUPLEX)
Harddisk0-LUN1-PLEX1 (Basic) 10/40/1 (DUPLEX)
information for non-RDR disks is the same, except that it does not include LUN (RDR
virtual disk) or PLEX (physical disk) information, which pertains only to RDR disks.
In the details pane:
•
Harddisk0 refers to the Windows disk name.
•
LUN1 refers to RDR virtual disk 1. (Your Express5800/320Ma system can support
a maximum of three RDR virtual disks: LUN 1, LUN 2, and LUN 3.)
•
PLEX1 and PLEX2 refer to the two physical disks that together make up RDR virtual
disk 1 (LUN 1).
•
Basic refers to type of disk. The other possible value is Dynamic.
•
10/40/1 indicates the following:
– 10 indicates I/O element 10.
– 40 indicates the internal storage enclosure within the I/O element.
– 1 indicates the bottom disk slot in rack-mounted systems.
• For RDR disks, Duplex indicates that the two physical disks of the RDR virtual
disks are partnered. If the two physical disks were not partnered, the displayed
value would be Simplex.
For non-RDR disks, the values in this position indicate the disk's operating status.
RDR virtual disks list DevicePath[1] and DevicePath[2] properties that indicate the
device ID of the disks that make up the virtual disk. However, the DevicePathID for an
RDR virtual disk does not indicate a hardware component, but instead identifies the
virtual disk to system-management software.

N O T E
In rack-mounted systems, I/O element 10 is in the top
enclosure and I/O element 11 is in the bottom enclosure.
Pedestal systems (not available in Express5800/320Ma
Dual-Core systems) are rotated 90 degrees clockwise,
so that I/O element 11 is on the left side (from the front) of
the system and I/O element 10 is on the right side.
