Port - HPE 3PAR StoreServ 8000 Service And Upgrade Manual

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

port 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.
