Parameters

No parameters are allowed or tested for.

Usage

  1. Seeks data collection and analysis for disk packs with a high I/O activity causes considerable overhead. Seeks EVENT data should, therefore, be enabled only for limited periods of time, and/or for a restricted number of disks.
  2. The Volume Serial and Disc Time msec information is obtained from I/O domain SAMPLE records. It can not be inserted before at least one (for Volume Serial) or two (for Disc Time msec) sample intervals have elapsed.
