Relative Disc Balance (RDBCHRT)
Relative Disc Balance (RDBCHRT)
This 74-column chart displays the relative logical disk volume balance, measured by
each volume’s total queuing time (external queuing plus internal queuing and service)
expressed as a percentage of the sum of the queuing time of all logical volumes,
shown as Shr% in the chart. The chart displays the component parts of this Shr%,
including:
•
External queuing
•
Internal queuing and service
•
Logical volumes for which the percentage of logical requests that encounter record
or file locks exceeds user-specifiable threshold (with a default of 1%)
This chart uses the DGLOBAL and DISCINFO entities.
Parameters used are:
•
LID—specifies the Measure Load ID
•
SECTION—specifies the report section number
The chart is sorted in descending order of total queuing and service time.
