Nachricht : PFR2861
:T Disk queue length exceeded guideline of &3.

Nachrichtenlangtext :

Technical description . . . . . . . . : The following table shows the arm identifier, the queue length and the date and time the queue length exceeded the guideline.
:I PFX2091
:T PFX205904
The queue length refers to the average number of disk I/Os waiting for service on a disk unit. A disk I/O must wait if the disk is busy servicing another disk I/O or it is servicing an error recovery procedure.
This problem is most often caused by over utilized disks, improperly balanced disk within an ASP, or files being unevenly spread after adding disk units. If the average queue length is greater than 10 times the guideline disk error recovery is probable and should be investigated.
To investigate disk arm activity see the Start Disk Collection command (STRDSKCOL)
