Connectivity

Symptom
Multiple sessions are established with the same target.
Probable cause and recommended action
All available ports are reported by SendTargets processing, and sessions are established for each
port to the same target and LUNs.
This can be controlled by configuring the iSCSI host initiator and the GbE port on the FC4-16IP
blade to allow only one connection per session by using the following command:
switch:admin> iscsiportcfg --modify <slot/ge<port>
-c 1
Also, if connection redirection is configured, it must be disabled by using the following command:
switch:admin> iscsiswcfg --disableconn -s <all>
Symptom
iSCSI host can log in to targets, but cannot mount any disks.
Probable cause and recommended action
The target is a RAID device, but iSCSI virtual initiators have not been added to the LUN mapping.
Add all iSCSI virtual initiators to the target and allow all iSCSI virtual initiators to access all of the
target LUNs. To display the WWNs of the iSCSI virtual initiators, use
nsShow
. Use the following
commands to fix this issue:
switch:admin> iscsiportcfg --modify <slot/ge<port>
-c 1
switch:admin> iscsiswcfg --disableconn -s <all>
Symptom
Easy create cannot find any LUNs on the target.
Probable cause and recommended action
The target is a RAID device, but the
fcLunQuery
WWN has not been added to the LUN mapping.
Add the
fcLunQuery
WWN to the target's LUN mapping. Display the WWNs using the
fcLunQuery -s
command.
Or the target is not compatible with
fcLunQuery
. Create a virtual target and add LUNs manually
using the
iscsiCfg
command.
Symptom
Cannot get GE ports to go to Online state.
Probable cause and recommended action
The GE ports are not connected to gigabit Ethernet interfaces.
Make sure the GbE ports are plugged into gigabit Ethernet interfaces. The GE ports cannot be
connected to Ethernet or fast Ethernet interfaces.
