PD Disks experiencing a high level of I/O per second 93
Component --Identifier-- ---------Description----------
PD disk:100 Disk is experiencing a high level of I/O per second: 789.0
PD Suggested Action 3
This check samples the I/O per second (IOPS) information in statpd to see if any disks are being
overworked, and then it samples again after five seconds. This does not necessarily indicate a
problem, but it could negatively affect system performance. The IOPS thresholds currently set for
this condition are listed:
• NL disks < 75
• FC 10K RPM disks < 150
• FC 15K RPM disks < 200
• SSD < 1500
Operations such as servicemag and tunevv can cause this condition. If the IOPS rate is very
high and/or a large number of disks are experiencing very heavy I/O, examine the system further
using statistical monitoring commands/utilities such as statpd, the OS MC (GUI) and System
Reporter. The following example shows a report for a disk with a total I/O is 150 kb/s or more.
