4. Checking the host settings
Check the following iSCSI settings of the host.
(4)-1 Checking the iSCSI parameter settings of the host
Check that the iSCSI settings of the host, including the initiator name, CHAP, and target portal,
are correct.
If the port number can be selected for the target specification settings of iSCSI initiator,
including an IP address and subnet mask, use the default port number (3260).
(4)-2 Checking the multi-session settings of the host
Check that the login setting of the host is not set to multi-session. For how to check the login
setting, refer to the manual of the host (software initiator).
Multi-session
If logging in to the same IP address (iSCSI port) of the disk array twice from the hosts with the
same name, the first login connection is disconnected.
Example: In the case of iSCSI Initiator on Windows Server 2003, if the same target is specified
to Persistent Targets twice or more
If the Automatically restore this connection when the system boots check box is selected at
login, the target is registered to the Persistent Targets tab of the Microsoft iSCSI Initiator dialog
box.
If the same target logs in to the disk array twice or more by specifying the same IP address, the
duplicated list is set to Persistent Targets, and the system enters a multi-session. If a duplicated
Target-IPaddress pair exists in Persistent Targets, delete the duplicated pair.
For details, refer to the manual of Microsoft iSCSI Initiator.
(4)-3 Checking whether the host logged in target on the disk array
Check whether the host is logging in the target on the disk array. For how to check, refer to the
manual of the host (software initiator). If the host is not logging in the target, check whether the
host is set to log in the target on the disk array.
For iSCSI Initiator software, it is possible to specify whether to automatically reconnect to the
host after rebooting the host. If the logical disk cannot recognized after rebooting the host,
check whether the automatic recognition settings are appropriate.
