There is an imbalance of active pd ports
PD Suggested Action 2
The primary and secondary I/O paths for disks (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. To diagnose further, use CLI commands such as
showpd
,
showpd path
,
showcage
, and
showcage -d
.
