As per my understanding of your question I am dividing answer in two parts  A)Yes symcli has not given option to get direct output for listing the initiator groups with wwpn in them at one go so I use below to find in my environment 1) to see the list of initiator groups and wwpns :-  for i in `symaccess -sid 30 list -type init | grep IG` ; do echo "##################### $i ";symaccess -sid 30 show $i -type init ; done  ( note : above comand is good if you have naming convention of IG_hostname or IG in the name and in case not then use the below )  for i in `symaccess -sid 30 list -type init` ; do echo "##################### $i ";symaccess -sid 30 show $i -type init ; done    ==> first few will be dummy output and you can modify it by using cut or grep accordingly  B) For getting the details of host -> devs -> tier we can use the below small script as we dont have single comand  for i in `symaccess -sid 30 show MV_host view | awk '{print $1}' | grep -v ':' | grep -i [0-9]`; do echo $i################################; symdev -sid 30 show $i | grep -i bound ; done  Note: give the view name of your host and SID as per your env then you can get host- dev - pool output .  Let me know if this helps and solves your purpose. If you get one comand without using scripts post to us also.
I have to build a report with the hosts accessing the Vmax and the devices they are connected to(if they are still within a masking view) and their tiering. Using list view I get a report on the groups and the masking views in the Vmax. But I do not have a command that gives me all the initiator groups and the wwns. There is the show command but that gives me only for one initiator group. Does anyone have any ideas on how I can go about this.   My requirements are   Host  ---   devices  ---- tiering   I have the tiering of the devices. But these hosts must belong to a masking view though.  Thanks in advance.
