service action, such as hardware or software upgrades, these exceptions can be ignored until that action
has finished and the node is online.
In this example, LD 35, with a name of R1.usr.3, is owned (
Own
) by nodes 3/2/0/1, respectively, and the
primary/secondary physical paths to the drives (chunklets) in this LD are from nodes 3 and 2,
respectively. However, the FC path (Port B) from node 3 to PD 91 is failed/missing, so node 2 is
performing the I/O to PD 91. When the path from node 3 to cage 3 gets fixed (N:S:P 3:0:4 in this
example), this condition must disappear.

port
Checks for the following port connection issues:
• Ports in unacceptable states
• Mismatches in type and mode, such as hosts connected to initiator ports, or host and Remote Copy
over Fibre Channel (RCFC) ports configured on the same FC adapter
• Degraded SFPs and those with low power; perform this check only if this FC Adapter type uses SFPs
• Ports listed as hosts in "showhost" that are not ready or not configured as host
• Host ports or systems with too many initiators connected

suggested actions, general
Some specific examples follow, but in general, use the following CLI commands to check for these
conditions:
For port SFP errors, use commands such as
showport
,
showport -sfp
, and
showport -sfp -ddm
.
