Component Description
Backend Transfer Non-Sequential Reads
The number of writes transferred on the backend to
the LDEV.
Backend Transfer Writes
The number of writes transferred on the backend to
the LDEV.
Display type (drop-down menu)
Indicates the type of information that is
displayed.Open System = Displays the open system
columns. Mainframes = Displays the mainframe
columns. Combined = Displays the open system
columns and the mainframe columns.
DFW Count
Disk Fast Write count. Counts that are relevant only
to mainframe volumes. These fields are zeros when
the emulation type starts with OPEN.
Emulation
An array group is divided into open volumes of equal
size. These volumes are referred to as emulation
types. If PA XP cannot determine the emulation
type, an error appears. The error does not affect
performance data collection.
NOTE:
The emulation type is displayed as "Not Known"
for emulations that start with "OPEN-XP".
E-LDEV The external LUN LDEV ID on the external array.
Ext-Lun
Indicates that the LDEV is an Ext-Lun. The following
options are available:- (hyphen) = Normal LUN E =
Ext-Lun P = Ext-Lun provider (this LDEV is used as an
Ext-Lun for another array)
E-Port(s)
A list of Ext-Lun initiator ports (ports used to connect
to an external array).
E-Seq The Ext-Lun provider’s serial number for the array.
Host ID (Host identifier)
The name of the host machine. PA XP discovers
LDEV-to-CHIP port connectivity. Unknown is displayed
if the host name is unknown. This automatic
CHIP-LDEV mapping works only for open volumes.
When using mainframe LDEVs, use the userhostcfg
CLUI to add mainframe hosts.
Host Group
The port host group. This component is available
only on XP1024/XP128/XP10000/XP12000 and
XP24000.
LDEV ID The identification number for the LDEV.
LDEV IO/s
The total I/Os per second for all random reads,
random writes, sequential reads, and sequential
writes during the reporting period.
LDEV MB/s The total megabytes per second for the LDEV.
Load Inhibit Count Count in Cache Load Inhibit Mode.
Luse
Indicates that the LDEV is a LUN Size Expansion
