HP StorageWorks P9000 Performance Advisor Software v5.3 User and Troubleshooting Guide (T1789-96322, August 2011)

DescriptionScreen elements
The external LUN LDEV ID on the external array.E-LDEV
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)
Ext-Lun
A list of Ext-Lun initiator ports (ports used to connect
to an external array).
E-Port(s)
The Ext-Lun provider's serial number for the array.E-Seq
The name of the host machine. P9000 Performance
Advisor discovers LDEV-to-CHIP port connectivity. Un-
known 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 ID (Host identifier)
The port host group. This component is available only
on the XP24000, XP20000, XP12000, XP10000,
and XP1024/XP128 type arrays.
Host Group
Displays the average IO size in KBs for the selected
LDEV. The average IO size is derived by dividing the
total MB/s with the total I/Os for that LDEV (IO size
= LDEV MB Total/LDEV IO Total).
IO Size
The continuous access journal pool IDs.Jnl Group
The identification number for the LDEV.LDEV ID
The total frontend I/Os for all random reads, random
writes, sequential reads, and sequential writes during
the reporting period.
LDEV IO/s
The total frontend throughput in MB/s for the LDEV.LDEV MB/s
Count in Cache Load Inhibit Mode.Load Inhibit Count
Indicates that the LDEV is a LUN Size Expansion
(Luse).E = Master C = Component
Luse
The LDEV number of the LUSE, when applicable.
• blank = The LDEV is not a Luse component
• M = Master for the Luse group
• C = Contributor to the Luse group
The Luse master LDEV also lists an entry for the contrib-
utor. If you are filtering by Host, you cannot see the
contributors, because they are not mapped externally.
If you show Requested Hosts connected to the array,
you can see the contributors in addition to the Luse
master.
Luse Status
The LDEV ID of the Luse master when the LDEV is a
component. If the LDEV is not a Luse component, this
field is blank.
Luse Master
