If you want to switch back to using the software initiator, enter the
following:
iscsiadm --mode node --targetname iqn.2004-
06.com.broadcom:tg1 \
--portal 192.168.1.100 --op=update \
--name=node.transport_name --value=tcp
Making Connections to iSCSI Targets
Refer to open-iscsi documentation for a comprehensive list of iscsiadm
commands. The following is a sample list of commands to discovery
targets and to create iscsi connections to a target:
Adding static entry
iscsiadm -m node -p <ipaddr[:port]> -T iqn.2007-
05.com.broadcom:target1 -o new
iSCSI target discovery using 'SendTargets'
iscsiadm -m discovery --type sendtargets -p
<ipaddr[:port]>
Login to target using 'iscsiadm' command
iscsiadm --mode node --targetname <iqn.targetname> --
portal <ipaddr[:port]> --login
List all drives active in the system
'fdisk -l'
Maximizing Offload iSCSI Connections
With default driver parameters set, which includes 128 outstanding
commands, bnx2i can offload a maximum of 28 iSCSI connections. This is
not a hard limit, but simple on-chip resource allocation math. The bnx2i
driver can offload > 28 connections by reducing the shared queue size
which, in turn, limits the maximum outstanding tasks on a connection. See
“Setting Values for Optional Properties” on page 74 for information on
sq_size and rq_size. The driver logs the following message to syslog when
the maximum allowed connection offload limit is reached - "bnx2i: unable
to allocate iSCSI context resources."
