Troubleshooting InServ Storage Server Components
Messages and Operator’s Guide InForm OS Version 2.3.1
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 InForm OS IMC
(GUI) and System Reporter. The following example will report disks whose total I/O is 150/sec or
more.

The identified disk does not have firmware that the InServ Storage Server 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 the state of the disk using CLI commands such as showpd -s,
showpd -i, and showfirmwaredb.
