host group
Contains LUs that can only be accessed by hosts within the group. Multiple host groups can exists on a
single port and each uses a single host mode
host mode Each port can be configured with various options referred to as host modes. These modes are represented
as a 2 digit hexadecimal number. The first hex digit represents special options; currently only number 10
is defined which represents Fast Wide SCSI protocol support. The second hex digit represents behavior for
a specific host. These two numbers may be combined. For example, mode 18 represents Fast Wide SCSI
protocol support on an HP-UX host.
LDEV Logical device
LUN Logical unit number. A LUN results from mapping a SCSI logical unit number, port ID, and LDEV ID to a
RAID group. The size of the LUN is determined by the emulation mode of the LDEV, and the number of
LDEVs associated with the LUN. For example, a LUN associated with two OPEN-3 LDEVs will have a size
of 4,693 MB.

port
The number of supported ports on an XP disk array is dependent upon the number of supported I/O slots
and the number of ports available per I/O adapter. The XP family of disk arrays supports SCSI, Fibre
Channel (FC/ AL), and ESCON I/O interfaces. I/O support may vary with the selected disk array. Ports
are named based upon their port group and port letter. Examples of port names include CL1-A through
CL1-R and CL2-A through CL2-R (letters I and O are skipped).
