Setting Up the Command Queue Depth

Set the number of commands allowed to be queued (command queue depth) on each LUN in the ETERNUS
DX storage systems from the LAN card. This setting optimizes the connection between the ETERNUS DX stor-
age systems and the server.
Model

*1: Recommended value = 512 ¸ (number of iSCSI ports that are connected to a single CA port) ¸ number of
LUNs
(Round the result down)
Use the value of "8" if the actual result is lower.
For HP-UX11iv3
Set the command queue depth using the disk device attribute "max_q_depth". The "max_q_depth" is set
using the "scsimgr" command.
Example:
-
Setting the command queue depth of disk20 to 8
# scsimgr save_attr -D /dev/rdisk/disk20 -a max_q_depth=8
Refer to the HP-UX manuals for details of the "scsimgr" command.
