Table 21 Components and metrics in LDEV Column Settings list (continued)
Description Screen elements
Indicates that the LDEV is an Ext-Lun. The following options
are available:- (hyphen) = Normal LUN E = Ext-Lun P = Ext-Lun
Ext-Lun provider (this LDEV is used as an Ext-Lun for another
array)
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. HP XP P9000 Performance
Advisor discovers LDEV-to-CHIP port connectivity. Unknown Host ID (Host identifier)
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.
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 IO Size
with the total I/Os for that LDEV (IO size = LDEV MB
Total/LDEV IO Total
).
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. Luse Status
• 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 contributor.
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.
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
The identification number of the LUN. LUN (Logical Unit Number) ID
The identification number of the MP blade that is currently
processing requests for an LDEV. The MP blade ID includes MP Blade Id
the cluster # and the blade location. For example,
MPB-1MA, where 1 indicates the cluster # and MA
indicates the blade location.
NOTE: This component is displayed only for the P9000
disk arrays.
