Can you please download the following script and execute on Client LPAR and probable destination VIOS. 

1. first on client LPAR to get list of target ports 
2. and then on probable destination VIOS to verify if they can host IO for the Client LPAR or not.

Please let me know of any suggestions or improvements.

Please send all screen outputs of running the script on Client LPAR and destination VIOS for analysis.

Copy file /tmp/lpm_cli_info file on to destination VIOS at same location to verify NPIV SAN Zoning.
or copy paste above info into file /tmp/lpm_cli_info on destination VIOS.
Then, execute same script /usr/local/bin/lpmwwpns on VIOS in oem_setup_env shell

There are        2 VIOS providing NPIV disks to nimtb187
They are vios1_nimtb184 vios2_nimtb185

Checking Inactive wwpns ..   C0507600091D002B
  C0507600091D0027
Target wwpn 204400a0b82697ac can be reached using inactive wwpn C0507600091D0027 via 3 adapters.
Target wwpn 204500a0b82697ac can be reached using inactive wwpn C0507600091D0027 via 3 adapters.

**** YES. VIOS nimtb184 CAN host Client LPAR nimtb187 like Source VIOS vios1_nimtb184 after LPM ****

Checking Inactive wwpns ..   C0507600091D0025
  C0507600091D0029
Target wwpn 202400a0b82697ac can be reached using inactive wwpn C0507600091D0029 via 3 adapters.
Target wwpn 202500a0b82697ac can be reached using inactive wwpn C0507600091D0029 via 3 adapters.

**** YES. VIOS nimtb184 CAN host Client LPAR nimtb187 like Source VIOS vios2_nimtb185 after LPM ****

 In order to host Client LPAR nimtb187, VIOS nimtb184 should be able to virtualize FC adapters for at least one set of inactive WWPNS listed above. 
 If not, verify zoning.
