powermt returns paths which map to multiple LUNs
Hello
We are running powermt command which displays the paths
e.g
Pseudo name=emcpoweraw
VPLEX ID=FNM00133700251
Logical device ID=6000144000000010F07C657BBC13D312
state=alive; policy=ADaptive; queued-IOs=0
==============================================================================
--------------- Host --------------- - Stor - -- I/O Path -- -- Stats ---
### HW Path I/O Paths Interf. Mode State Q-IOs Errors
==============================================================================
4 qla2xxx sdla 04 active alive 0 1
4 qla2xxx sdjx 04 active alive 0 1
4 qla2xxx sdiu 04 active alive 0 1
3 qla2xxx sdw 0D active alive 0 1
3 qla2xxx sdbh 09 active alive 0 1
4 qla2xxx sdci 04 active alive 0 2
3 qla2xxx sddm 01 active alive 0 1
4 qla2xxx sdep 0C active alive 0 2
3 qla2xxx sdfs 05 active alive 0 1
4 qla2xxx sdgo 00 active alive 0 2
4 qla2xxx sdhr 08 active alive 0 2
If we trace back the LUNs for sdla, sdjx etc, we expect all the paths mapping to same LUN.
However we are getting multiple LUNs.
e.g
lrwxrwxrwx 1 root root 0 Jun 26 00:07
/sys/class/scsi_host/host4/device/rport-4:0-0/target4:0:0/fc_transport:target4:0:0/device/4:0:0:49173/block:sdla
-> ../../../../../../../../block/sdla
Similarly for others....
lrwxrwxrwx 1 root root 0 Jun 26 00:07
/sys/class/scsi_host/host4/device/rport-4:0-0/target4:0:0/fc_transport:target4:0:0/device/4:0:0:32789/block:sdjx
-> ../../../../../../../../block/sdjx
lrwxrwxrwx 1 root root 0 Jun 26 00:07
/sys/class/scsi_host/host4/device/rport-4:0-0/target4:0:0/fc_transport:target4:0:0/device/4:0:0:16404/block:sdiu
-> ../../../../../../../../block/sdiu
lrwxrwxrwx 1 root root 0 Feb 20 2015
/sys/class/scsi_host/host3/device/rport-3:0-0/target3:0:0/fc_transport:target3:0:0/device/3:0:0:22/block:sdw
-> ../../../../../../../../block/sdw
Why multiple paths pointing to different lun # ? Is this possible and what does it indicate.
