The LUSE master ID (M), if an LDEV is configured as an LUSE Master.

The associated E-Port list, which is a list of Ext-Lun initiator ports that are used to connect
E-Port(s) to an external array.

The associated E-Seq, which is the Ext-Lun provider's serial number for the E-seq(s) array.

The associated E-LDEV, which is the external LUN LDEV ID on the external array.

The associated CLPR group ID.

IMPORTANT:

For a P9500/XP7 disk array, the ldev_exportDB file displays an additional

Current MP column. This column displays the current MP blade for each LDEV record. The MP
blade ID includes the cluster # and the blade location for the MP blade.

dkc_exportDB-array_serial_number_<file_name>.csv

This file includes the following details:

The

XP/XP7 disk array serial number for which the report is generated.

The

array type to which the selected XP or XP7 disk array serial number belongs.

The performance data collection interval time stamps.

The size of the cache and the MB/s of cache used over an entire collection interval.

The percentage of writes that are held in the cache, yet to be transferred to the disks over an
entire collection interval.

The MB/s of the continuous access asynchronous sidefile usage over an entire collection
interval.

The data accessed or the reads on a single CLPR over an entire collection interval.

The utilization of the shared memory CHIP/CHA and ACP/DKA transfer bus, and the utilization
of the cache memory CHIP/CHA and ACP/DKA transfer bus.

For an XP disk array, the individual MP processor utilization data for the CHIPs/CHAs and the
ACPs/DKAs are also displayed in addition to the above-mentioned information.

For

an XP7 disk array, the dkc_exportDB does not include the CHIP/CHA MPs and the ACP/

DKA

MPs utilization data. Instead, the MP blades that reside on the XP7 disk array and their

average

utilization percentage are displayed.

IMPORTANT:

Since,

the CHIP/CHA and the ACP/DKA MPs are moved to the MP blades in

the

XP7 disk arrays, their MP utilization metrics are not applicable for the XP7 disk arrays.

port_exportDB-array_serial_number_<file_name>.csv

This file includes the following details:

The

XP/XP7 disk array serial number for which the report is generated.

The

port IDs on the XP/XP7 disk array. The port type, such as Fibre or FCoE (applicable only

for

XP7 disk arrays) is also displayed beside the CHIP port ID.

The performance data collection interval time stamps.

The maximum and the minimum frontend I/Os on a port over an entire collection interval.

The average frontend I/Os on a port over an entire collection interval.

The maximum and minimum frontend throughput in MB/s that was read from or written to the
port in the last 30 seconds of the collection interval.

The average frontend throughput in MB/s that was read from or written to the port over an
entire collection interval.
