About LUN queue depth (max_q_depth) in HP-UX operating systems, hp-uxmax_q_depth
Originally I don't know how to view the LUN queue depth under the HP-UX operating system, then I consulted a buddy in the white eel group-network neighbors, he gave the answer:

HPUX (Q-depth 8 by default)
# Scsimgr get_attr-D/dev/rdisk/disk ?? Or # scsimgr-p get_attr all_lun-a device_file-a max_q_depth
# Scsimgr set_attr-D/dev/rdisk/disk ?? -A load_bal_policy = round_robin
# Scsimgr save_attr-D/dev/rdisk/disk ?? -A max_q_depth = 8
In fact, in hp-ux, this parameter is called max_q_depth. By default, the value of this parameter is 8.
