DescriptionScreen elements
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
The identification number of the LUN.LUN (Logical Unit Number) ID
The identification number of the MP blade that is cur-
rently processing requests for an LDEV. The MP blade
ID includes 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.
MP Blade Id
The maximum read response time, in millisecond, for
the LDEV.
Max Read Resp (msec) - valid for last 30 secs
The maximum write response time, in millisecond, for
the particular LDEV.
Max Write Resp (msec) - valid for last 30 secs
The RAID group to which the LDEV belongs.RG
The random frontend reads throughput in MB/s for
the LDEV.
Random MB Reads – Frontend
The random frontend writes throughput in MB/s for
the LDEV.
