Hi,

I tested as well with ESXi 5.1 and I could not login with ESXi as initiator
The error from tgtd was as follows:

tgtd: add_mode_page(1648) Mode Page 10 (0x01): param_count 6 != MODE
PAGE size : 31


I checked for commits between 1.0.29 - 1.0.30 that modify or call this
function and found
that commit 9a95b4431ccc01b82cb4febc735485cd06cd5ea4 added a new call
to add_mode_page()
and the error is the result of that new call:

518	+  /* Control Extensions mode page:  TCMOS:1 */
519	+  add_mode_page(lu, "0x0a:1:0x1c:0x04:0x00:0x00");


After removing this call ESXi logged in fine and without any problems.

frederik,
mind trying it as well?

Thanks,
Roi
