Re: dynamically adjust session values?
Mike, You said that this is not dynamic. Do you know if there are plans to make it dynamic? I'm not sure if this is part of the RFC or not. I am thinking that it could be done using async-logout maybe?

I am thinking that it could be done using async-logout maybe? It does not have anything to do with the RFC. We have discussed on the list how to discuss it, but we just never have. I will put it on the todo. For some settings like iscsi segment lens, we would have to logout then relogin. For timer settings like below we can just set them and we do not need to relogin.

dynamically adjust session values?
Hi all, I'm looking to globally adjust my session timeouts dynamically, if possible. I have found that if I adjust /etc/iscsi/iscsid.conf and change the following two values and then run `iscsiadm -m discovery -t st -p portal_ip_here`, it will use whatever is in iscsid.conf and update the database files in /var/lib/iscsi/nodes/etc..etc../iface0 and iface1 (or however many more ifaces you have). So here's what I've done: 1) see what the timeouts are currently set to for my first session: [root@oim61024005 ~]# iscsiadm -m session -r 1 -o show | grep noop node.conn[0].timeo.noop_out_interval = 15 node.conn[0].timeo.noop_out_timeout = 15 2) adjust iscsid.conf with new values [root@oim61024005 ~]# grep noop /etc/iscsi/iscsid.conf node.conn[0].timeo.noop_out_interval = 5 node.conn[0].timeo.noop_out_timeout = 5 3) run my global discovery: [root@oim61024005 ~]# iscsiadm -m discovery -t st -p 192.168.1.48 /dev/null 4) verify that session 1 now shows the new timeouts: [root@oim61024005 ~]# iscsiadm -m session -r 1 -o show | grep noop node.conn[0].timeo.noop_out_interval = 5 node.conn[0].timeo.noop_out_timeout = 5 [root@oim61024005 ~]# Can others verify if this actually updates the values dynamically?
