Determine vendor specific internal storage LUN identifier
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 |- 5:0:1:96 sdct 70:16 active ready running `- 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)?
