I apologize if this is a dumb question, but I am new to iSCSI. (Well,
at this level of detail, I am new to SCSI in general.)
I have been browsing the source code (open-iscsi-2.0-871), and I am
curious about the following iscsid.conf parameters:
node.session.initial_cmdsn
initial cmd_sn is some internal value that could have been be useful for
testing iscsi targets or a workaround for some targets. It is not really
implemented.
node.session.cmds_max
node.session.queue_depth
from iscsid.conf comments:
################################
# session and device queue depth
################################
# To control how many commands the session will queue set
# node.session.cmds_max to an integer between 2 and 2048 that is also
# a power of 2. The default is 128.
node.session.cmds_max = 128
# To control the device's queue depth set node.session.queue_depth
# to a value between 1 and 1024. The default is 32.
node.session.queue_depth = 32
