11.4.8.4 PD Example 2
Component --Identifier-- --------------Description---------------
PD -- There is an imbalance of active pd ports
11.4.8.5 PD Suggested Action 2
The primary and secondary I/O paths for disks (PD's) 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 usually caused by a nonfunctioning path/loop to a cage, or because
an odd number of drives is installed or detected. To diagnose further, use CLI commands such
as
showpd, showpd path, showcage, and showcage -d.
