Hi Nick, I went through the source in a little more detail and figured out why I was hitting the 256 target count limit. The addlun operation was failing on LUN# 256. I just found the 256 LUNs per PG limit in target_core_base.h. Thanks, -Joe ----- Original Message ----- From: Nicholas A.

The current value of 256 bytes is fairly arbitrary, and using 1024 (or anything else that is a PAGE_SIZE or below) should be OK. --nab -- To unsubscribe from this list: send the line "unsubscribe target-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
