                                                ls -l /sys/class/scsi_host/<a qla2xxx host>/vport_*
   ls -l /sys/class/scsi_host/<a qla2xxx host>/vport_id
   ls -l /sys/class/scsi_host/<a qla2xxx host>/vport_disable
   ls -l /sys/class/scsi_host/<a qla2xxx host>/symbolic_port_name

实际结果:

--w--w--w- root root  /sys/class/scsi_host/host1/vport_create
--w--w--w- root root  /sys/class/scsi_host/host1/vport_delete
--w--w--w- root root  /sys/class/scsi_host/host2/vport_create
--w--w--w- root root  /sys/class/scsi_host/host2/vport_delete

预期结果:

-rw-r--r-- root root  /sys/class/scsi_host/host1/vport_create
-rw-r--r-- root root  /sys/class/scsi_host/host1/vport_delete
-rw-r--r-- root root  /sys/class/scsi_host/host2/vport_create
-rw-r--r-- root root  /sys/class/scsi_host/host2/vport_delete
