pd Suggested Action 2
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 usually caused by a non-functioning path/loop to a 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.
