For future reference for others on the mailing list who might try a similar procedure in the future I also received a useful response from Matt Hallmark which points out that you also need to keep the target portal group tags the same for *nix/esx hosts.<br>

You will run into trouble, with all *nix/esx hosts if the iSCSI Target Portal Group tag(s) change.<br>
<br>
goliath&gt; iscsi tpgroup show<br>
TPGTag  Name              Member Interfaces<br>
    1   e0a_old           (none)<br>
 1004   e3a_default       e3a<br>
 1005   e3b_default       e3b<br>
 2000   VIF_e0_AC_default  VIF_e0_AC<br>
 2001   VIF_e0_BD_default  VIF_e0_BD<br>
<br>
Those are changable, but would require an iSCSI maintenance window to complete.<br>
