Description
Screen elements
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.
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.
Random MB Writes - Frontend
The random frontend I/O reads.
Random Reads - Frontend
The random frontend I/O read cache hit values.
Random Read Cache Hits - Frontend
The random frontend I/O write cache hit values.
Random Write Cache Hits - Frontend
The random frontend I/O read write values.
Random Writes - Frontend
The sequential frontend I/O read cache hit values.
Sequential Read Cache Hits - Frontend
The sequential frontend I/O read values.
Sequential Reads - Frontend
The sequential frontend I/O write values.
Sequential Writes - Frontend
The sequential frontend reads throughput in MB/s for the
LDEV.
Sequential MB Reads - Frontend
The sequential frontend writes throughput in MB/s for the
LDEV.
Sequential MB Writes - Frontend
The sequential frontend write cache hit values in per
second.
Sequential Write Cache Hits - Frontend
The identification number of the subsystem.
SS ID
The SLPR group ID.
NOTE:
SLPR does not exist in the P9000 disk arrays. So,
the SLPR group ID is displayed only for the XP disk arrays.
SLPR
The LUN associated with the given LDEV.
Target LUN
The volume group identification name if the device is
associated with a volume group. HP XP P9000 Performance
Vol. Group
