Troubleshooting

Problem
iSCSI initiator cannot
add a discovery portal
iSCSI initiator cannot
connect to target portal
iSCSI initiator connects
to target portal but does
not report any targets
iSCSI initiator finds
iSCSI targets but can not
login
iSCSI initiator logs into
iSCSI targets but does
not see any LUNs
iSCSI configuration was
lost during a MSA1510i
chassis swap out
Possible cause / solution
The initiator name in the iSCSI initiator software does not match the name entered
for the initiator in the MSA1510i SMU or CLI.
• 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.
• 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.
• 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.
• Check the Access Control List for the iSCSI target.
• No LUNs configured for the iSCSI target in the MSA1510i.
• All iSCSI information is tied to the serial number of the device. Swapping
chassis results in a change in the serial number.
