Troubleshooting Problem Possible cause / solution iSCSI initiator cannot The initiator name in the iSCSI initiator software does not match the name entered add a discovery portal for the initiator in the MSA1510i SMU or CLI. iSCSI initiator cannot connect to target portal • Storage port with target portal is not connected to the network. • Wrong IP address or TCP port number. • No IP route from the initiator to the MSA1510i target portal. • No IP route from the MSA1510i target portal back to the initiator. • Initiator is on a different VLAN than the MSA1510i target portal. • Bad cable connected to the network. • Other network problem; verify connectivity to the management port with ping command. • MSA hardware problem - check status LEDs and front panel messages. iSCSI initiator connects to target portal but does not report any targets • Initiator is not on the access control list for any targets. • No targets are configured on the MSA1510i. • Portal is not bound to a target portal group in an iSCSI target. • Add at least one, preferably all target portals into the Discovery list in the Microsoft iSCSI initiator software, and then click Refresh to update the target list. iSCSI initiator finds iSCSI targets but can not login • Examine the target statistics for failed logins in the Storage Management Utility. • CHAP logon information improperly configured in the iSCSI initiator advanced login options. • IP-SEC incorrectly enabled on the iSCSI initiator advanced login options. • Targets may be configured for the second port on the controller. Be sure that both ports are connected to the proper IP subnet with access to initiator. • The MSA controller maximum session count may have been exceeded. The controller supports a maximum of 32 sessions per controller. Log out of targets on any non-essential servers to free some sessions. iSCSI initiator logs into iSCSI targets but does not see any LUNs • Check the Access Control List for the iSCSI target. • No LUNs configured for the iSCSI target in the MSA1510i. iSCSI configuration was lost during a MSA1510i chassis swap out • All iSCSI information is tied to the serial number of the device. Swapping chassis results in a change in the serial number. 1510i Modular Smart Array installation and user guide 75

Troubleshooting
Problem
Possible cause / solution
iSCSI initiator cannot
add a discovery portal
The initiator name in the iSCSI initiator software does not match the name entered
for the initiator in the MSA1510i SMU or CLI.
iSCSI initiator cannot
connect to target portal
•
Storage port with target portal is not connected to the network.
•
Wrong IP address or TCP port number.
•
No IP route from the initiatorto the MSA1510i target portal.
•
No IP route from the MSA1510i target portal back to the initiator.
•
Initiator is on a different VLAN than the MSA1510i target portal.
•
Bad cable connected to the network.
•
Other network problem; verify connectivity to the management port with
ping
command.
•
MSA hardware problem – check status LEDs and front panel messages.
iSCSI initiator connects
to target portal but does
not report any targets
•
Initiator is not on the access control list for any targets.
•
No targets are con
fi
gured on the MSA1510i.
•
Portal is not bound to a target portal group in an iSCSI target.
•
Add at least one, preferably all target portals into the Discovery list in the
Microsoft iSCSI initiator software, and then click
Refresh
to update the target
list.
iSCSI initiator
fi
nds
iSCSI targets but can not
login
•
Examine the target statistics for failed logins in the Storage Management
Utility.
•
CHAP logon information improperly con
fi
gured in the iSCSI initiator advanced
login options.
•
IP-SEC incorrectly enabled on the iSCSI initiator advanced login options.
•
Targets may be con
fi
gured for the second port on the controller. Be sure that
both ports are connected to the proper IP subnet with access to initiator.
•
The MSA controller maximum session count may have been exceeded. The
controller supports a maximum of 32 sessions per controller. Log out of targets
on any non-essential servers to free some sessions.
iSCSI initiator logs into
iSCSI targets but does
not see any LUNs
•
Check the Access Control List for the iSCSI target.
•
No LUNs con
fi
gured for the iSCSI target in the MSA1510i.
iSCSI con
fi
guration was
lost during a MSA1510i
chassis swap out
•
All iSCSI information is tied to the serial number of the device. Swapping
chassis results in a change in the serial number.
