The following power path command will display all of the LUNS seen by the Linux host.
[root@dc02nbkp004 bin]# powermt display dev=all
The output looks like the following.
Pseudo name=emcpowera
Symmetrix ID=000192601978
Logical device ID=1E00
state=alive; policy=BasicFailover; queued-IOs=0

To count the number of LUNS seen by the host I pick a unique string for each LUN and grep the output counting those lines that contain “Logical”. This gives the the number of LUNS seen by the host.
[root@dc02nbkp004 bin]# powermt display dev=all |grep Logical |wc -l
109
