Hi,

i have a debian Etch x86_64 with a xen 3.1 on a kernel 2.6.18-xen.
I have some DomU with Debian Etch.
I installed open-iscsi, configure  /etc/iscsi/iscsid.conf:
---
node.active_cnx = 1
node.startup = automatic
#node.session.auth.username = dima
#node.session.auth.password = aloha
node.session.timeo.replacement_timeout = 120
node.session.err_timeo.abort_timeout = 10
node.session.err_timeo.reset_timeout = 30
node.session.iscsi.InitialR2T = No
node.session.iscsi.ImmediateData = Yes
node.session.iscsi.FirstBurstLength = 262144
node.session.iscsi.MaxBurstLength = 16776192
node.session.iscsi.DefaultTime2Wait = 0
node.session.iscsi.DefaultTime2Retain = 0
node.session.iscsi.MaxConnections = 0
node.conn[0].iscsi.HeaderDigest = None
node.conn[0].iscsi.DataDigest = None
node.conn[0].iscsi.MaxRecvDataSegmentLength = 65536
#discovery.sendtargets.auth.authmethod = CHAP
#discovery.sendtargets.auth.username = dima
#discovery.sendtargets.auth.password = aloha

node.conn[0].timeo.login_timeout = 15
node.conn[0].timeo.logout_timeout = 15
node.conn[0].timeo.noop_out_interval = 10
node.conn[0].timeo.noop_out_timeout = 15
---

i checked the LUN:
# iscsiadm -m discovery -t sendtargets -p 192.168.1.60:3260
# iscsiadm --mode node --targetname iqn.toto --portal 192.168.1.60.10:3260
# /etc/init.d/open-iscsi restart

It seems to work but i can't have any disk in the log
/var/log/messages /var/log/syslog.

Is there a howto to setup this correctly?

Did you setup the Equalogic box correctly?

Is there iqn filtering on the Equalogic?

Is there CHAP authentication setup on the Equalogic?
