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 (5) seconds. This does not necessarily indicate
a problem, but it could negatively affect system performance. The IOPS thresholds currently set for
this condition are as follows:
• 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 IMC (GUI) and System
Reporter. The following example will report disks whose total I/O is 150/sec or more.

PD Example 4
Component --Identifier-- -------Description----------
PD disk:3 Detailed State: old_firmware
PD Suggested Action 4
The identified disk does not have firmware that the storage system considers current. When a disk
is replaced, the servicemag operation should upgrade the disk's firmware. When disks are
installed or added to a system, the admithw command can perform the firmware upgrade. Check
