Determine vendor specific internal storage LUN identifier

Solution Unverified - Updated -

Issue

  • What native Linux OS command(s) do I use to get the same storage LUN ID {internal EMC identifier} that EMC inq provides? For example, EMC inq shows me that the storage LUN ID is 3929 for the following multipath device:

# /opt/sa/sa_tools/inq.linux -nodots | grep /dev/dm-193
/dev/dm-193     :EMC     :SYMMETRIX       :5874  :3803929000 :    35654400

# /opt/sa/sa_tools/inq.linux -nodots | grep /dev/dm-193 | awk '{print $1"  "substr($5,5,4)}'
/dev/dm-193  3929


Multipath device showing SCSI standard WWID (World Wide unique IDentifier):

            mpathde (360000970000192606438533033393239) dm-193 EMC,SYMMETRIX
            size=34G features='1 queue_if_no_path' hwhandler='0' wp=rw
            `-+- policy='service-time 0' prio=1 status=active

              `- 7:0:1:96 sdgm 132:32  active ready running
  • How do I get the internal storage LUN identifier 3929 using native Linux OS command(s)?
