A path was excluded from the items subject to automatic failback. 
PathID =

Details

A path was excluded from being subject to automatic failbacks because the 

system judged that an intermittent error was occurring in that path.

aa...aa

: Path ID (same as PathID of

-path

) (decimal (base-10) number)

Action

An intermittent error has occurred. Check the path for any possible problems. For 

details on what to do, see 

5.3 What To Do for a Path Error

 and switch the path 

shown in the message into Online.

KAPL08032-I

A path was recovered. (PathID =
