PD disk:100

pd Suggested Action 3

This check samples the I/O per second (IOPS) information in statpd to see if any drives 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:
NL drives < 75
FC 10K RPM drives < 150
FC 15K RPM drives < 200
SSD < 12000
Operations such as servicemag and tunevv can cause this condition. If the IOPS rate is very
high and/or a large number of drives are experiencing very heavy I/O, examine the system further
using statistical monitoring commands/utilities such as statpd, the OS SSMC (GUI) and System
Reporter. The following example reports drives whose total I/O is 150/sec or more.
