Re: PowerPath VE 5.8

Hi,

  • When powermt display hba is used, the Stats Q-IO displays the current total number of outstanding I/Os on this HBA.
  • When powermt display dev=all is used, the Stats Q-IO displays the total number of I/O operations under way to this path. This is the total number of I/O requests to this device that have not completed.
  • The sum of in-progress I/Os for all paths should equal the number of in-progress I/Os for the PowerPath device.

Regards,

Suman Pinnamaneni
