I recently found out how nice AIX and vpaths are.
Adding a SVC managed vdisk to a host is an easy job. Although when you by mistake add a wrong SVC Port into the SAN Zoning you can run into some trouble. If you delete the wrongly added port the vpath will be marked as degraded and one path of it as dead (normal) . After adding the correct port of the SVC to the Zoning just issue the command “addpaths” and the paths will be rescanned. Then the new path will be listed in the “datapath query device” list.
To remove the dead path just issue following command:” datapath remove device <vpathid> path <pathtoberemoved>”
Thats it. Quite easy
