The primary and secondary I/O paths for drives (PDs) are balanced between nodes. The primary path is
indicated in the showpd -path output and by an asterisk in the showpd output. An imbalance of active
ports is caused by a nonfunctioning path/loop to a drive enclosure (cage), or because an odd number of
drives is installed or detected, or drives were installed in the wrong slots. To diagnose further, use CLI
commands such as showpd, showpd -path, showcage, and showcage -d.

PD Disks experiencing a high level of I/O per second
Component --Identifier-- ---------Detailed Description----------
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 IOPS
• FC 10K RPM drives < 150 IOPS
PDs FC/10K/450GB unbalanced. Primary path: 5 on Node:0,3 on Node:1
