Symcli handles many of the checks you are after natively. Here are some examples to get you started...

Thin devices that are no not mapped to an FA:

symdev list -thin -noport

Thin devices that are not in a Storage Group:

symdev list -thin -notinsg

Tdevs no bound to a pool:

symdev list -tdev -unbound

Devices Mapped to a port but not in an MV (not valid for DMX):

symaccess list no_assignment

List WWN's that are in the login history table, but not currently logged in:

symaccess -sid 55 list logins | grep -v "Yes    Yes"

To check WWN's that are in the login history table, but not in an IG, put a couple of commands together:

for wwn in $(symaccess -sid 00 list logins | grep ^[0-9] | cut -c 1-16); do

   echo " checking wwn $wwn"

   symaccess -sid 55 -type initiator list -wwn $wwn > /dev/null 2>&1

   if [ $? -ne 0 ];then

      echo "$wwn not in any IG"

   fi

done

Minor efficiency update to the script (avoid processing the same WWN multiple times):

for wwn in $(symaccess -sid 00 list logins | grep ^[0-9] | cut -c 1-16 | sort | uniq); do

   echo " checking wwn $wwn"

   symaccess -sid 55 -type initiator list -wwn $wwn > /dev/null 2>&1

   if [ $? -ne 0 ];then

      echo "$wwn not in any IG"

   fi

done
