I am connecting 2 iscsi arrays to the same network port on a linux box
over the network. One device works fine. The other gets the dreaded
conn(1011) errors.
eth1 Link encap:Ethernet HWaddr 00:1D:09:2F:15:B2
inet addr:128.128.101.92 Bcast:128.128.103.255 Mask:

do I need to create an iface for each? is each considered a "network
object"? or can they share the one I created:
more /var/lib/iscsi/ifaces/iface1
iface.transport_name = tcp
iface.hwaddress = 00:1D:09:2F:15:B2
could this be the source of my conn(1011) disconnect errors in /var/
log/messages?
Has anyone out there been able to get an "Arena SS-6603R" to work with
any iscsi version?
target discovery seems to work, and I can log in. However, the logs
fill up with this:
/var/log/messages.1:Feb 25 15:32:37 ndsfdh1 iscsid: Kernel reported
iSCSI connection 6:0 error (1011) state (3)
/var/log/messages.1:Feb 25 15:32:40 ndsfdh1 iscsid: connection6:0 is
operational after recovery (1 attempts)
I can then actually create a partition, create a file system on it and
then mount it. But after about 10-15 minutes, the filesystem becomes
unreadable and has to be unmounted/redone.
I've tried changing timeouts, however I don't know which timeouts are
the correct ones to change, by how much and if it will negatively
effect the working iscsi array. Are there some general troubleshooting
guidelines on which values are likely to have an effect and what
acceptable ranges are for operation? Do vendors of these iscsi devices
set their own acceptable ranges based on the RFC or is it not
standard?
iscsiadm -m node -T iqn.2010.09.maxtronic.com:732af838098e3a24:ist1 |
grep timeout :
node.session.timeo.replacement_timeout = 120
node.session.err_timeo.abort_timeout = 15
node.session.err_timeo.lu_reset_timeout = 20
node.session.err_timeo.host_reset_timeout = 60
node.conn[0].timeo.logout_timeout = 15
node.conn[0].timeo.login_timeout = 15
node.conn[0].timeo.auth_timeout = 45
node.conn[0].timeo.noop_out_timeout = 10
thank you for any suggestions
