max_conn is not supported because we do not do MC/s. iscsi_sfnet did not either. For the IO limits you can set # 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 You can set this in the iscsid.conf file then redicover and relogin to the targets or run iscsiadm -m node -T target -o update -n name_of_setting_above -v then relogin. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "open-iscsi" group.
