Adding second ESX host to an existing masking view

Hello folks,

I have the need to add a second ESX host to an existing masking view and was wondering the best approach.

currently i have one masking view named ATERNITY_MV with one Port group OS_1F0_16F0_5F0_12F0 and one storage group name ATERNITY_SG.

the initiator group is name PHX_VMW_463_IG with the two wwn's in it.

my question is do i just add the new server wwn's to the existing IG group and change the name or is there a better way?

symaccess -sid 6679 show view ATERNITY_MV
