◦ Total IO, Inhibit Mode IO Count, and Bypass Mode IO Count.
◦ Backend Transfer Sequential Reads, Backend Transfer Non-Sequential Reads, and Backend
Transfer Writes.
◦ Random MB Reads and Random MB Writes.
◦ Sequential MB Reads and Sequential MB Writes.
◦ Average Read Response Time (msec) data for every 200 msec and Maximum Read
Response Time (msec) data for the last 30 seconds.
◦ Average Write Response Time (msec) data for every 200 msec and Maximum Write
Response Time (msec) data for the last 30 seconds.
•
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 P9000 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_.csv
This file includes the following details:
•
The XP or the P9000 disk array serial number for which the report is generated.
•
The array type to which the selected XP or P9000 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 a P9000 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 P9000 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
P9000 disk arrays, their MP utilization metrics are not applicable for the P9000 disk arrays.
