DescriptionScreen elements
The total frontend IO/s 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
Logical Unit Size Expansion. The LDEV number of the
LUSE, when applicable.
• blank = The LDEV is not a Luse resource
• 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
Logical Unit Size Expansion. The LDEV ID of the Luse
master when the LDEV is a resource. If the LDEV is not
a Luse resource, this field is blank.
Luse Master
The identification number of the LUN.LUN (Logical Unit Number) 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.RAID Group
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.
