OceanStor UltraPath for AIX 21.1.0 User Guide 04

In a SAN environment, there are four paths between the AIX application server and the storage system. However, the AIX application server detects five paths after scanning operations are performed. The fifth path's state is Failed.

Redundant unavailable paths are occasionally reported to AIX operating systems.

1. Log in to the AIX application server as user root.
2. Run lspath -l hdisk3 -F"name:parent:connection:status" to list all paths of the LUN, as shown in the following output (hdisk3 used as an example):
   Figure 6-3  Listing all paths of a LUN
   
   

3. As circled in the red line, the redundant path of hdisk3 is on fscsi0. Run rmpath -l hdisk3 -p fscsi0 -d to delete the redundant path between hdisk3 and fscsi0.
   NOTE:

   If the system indicates a command execution failure, repeat running the command until the redundant path is deleted.

4. Run lspath -F"name:parent:connection:status:path_id"|grep hdisk3 to check whether paths are normal on hdisk3.
   • If yes, no further action is required.
   • If no, keep the fault environment intact and contact technical support engineers.
