Dear all,

   I have a question about the RMF III Device Resource Delay report

   I noticed that the DLY% value of one disk is 100 every 6 minutes. This disk 
has HyperPAV enabled. 
   
   ACT RATE = 5.1,RESP TIME=200 ACT%=2 CON%=1 DSC%=1 USG%=0 DLY%=100
 

   According to the IBM manual, DLY% means "Percentage of time when the job was 
waiting to use the data set because of contention for the volume were the data 
set resides".

   I would like to know how to identify the cause of this contention. What 
command should I use? Do I need to enable GRS MONITOR?

  Any suggestions would be greatly appreciated!

Thank you for your attention and assistance.

Sincerely,

Jason Cai
