Component Description
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
(Luse).E = Master C = Component
Luse Status
Logical Unit Size Expansion. The CU:LDEV
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
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 m aster.
Luse Master
LogicalUnitSizeExpansion.TheLDEVIDoftheLuse
master when the LDEV is a component. If the LDEV is
not a L use component, this field is blank.
LUN (Logical Unit Number) ID
The ident
ification number of the LUN.
Max Read Resp (msec)-valid for last 30 secs The maximum read response time, in millisecond, for
the LDEV.
Max Write Resp (msec)-valid for last 30 secs The maximum write response time, in millisecond, for
the particular LDEV.
Overall % RGUtil
The o ver
all utilization percentage for a RAID group.
RAID Grp
The RAID group to which the LDEV belongs.
Random MB Reads
The random read value in megabytes per second for
the LDEV.
Random
MB Writes
The random write value in megabytes per second for
the LDEV.
Refresh (button) Click to refresh the view on the screen and to display
the current data in the database. When you click
Refresh, the current query appears. To perform a new
query, return to the Grid Display Query screen.
RIO Reads The random IO read value per second.
RIO Read Cache Hits The random IO read cache hit values per second.
RIO Write Cache Hits The random IO write cache hit value per second.
RIO Writes
The random IO read write values per second.
SIO R
ead Cache Hits
The s
equential IO read cache hit values per second.
SIO Reads The sequential IO read values per second.
SIO W rites
The sequential IO write values per second.
Sequential MB Reads The sequential read values in megabytes per second
for
the LDEV.
Sequential MB Writes The sequential write values in megabytes per second
for the LDEV.
