1. Checking the iSCSI port settings
If the disk array did not correspond to ping, check (1)-1 and (1)-2. After checking them, go to the
steps described below:
When using iSNS: (2) Checking iSNS

When not using iSNS: (3) Checking the LD Set settings of the disk array

1-1. Checking linkup
Check the port to which the disk array and connected devices such as a host and switch are
connected is correctly linkup.
Check method
The Link LED of the iSCSI port of the disk array is lit, the port is linkup. If the port is not linkup,
check which of the following (a to c) is the LED status of the port.
When the Ready LED of the controller is not blinking, the disk array is not online. Check
the following when the disk array is online.
a. The Link LED and Active LED blink twice every two seconds
The iSCSI settings such as an IP address and subnet mask of the port have not been set, or
they are invalid. Specify the iSCSI settings again by using the NEC Storage Manager
initialization wizard. It is thought that Node Name (WWnn) of the disk array has not been set. If
the LEDs are still blinking, after the iSCSI settings of the port have been correctly specified,
check the Node Name of the disk array is correctly set.
b. The Link LED and Active LED blink once every two seconds
The port is offline. Check whether the disk array is being shut down.
c. The Link LED and Active LED are not lit
In the case of 10Gbps iSCSI, check whether the connected devices such as a host and
switches support 10Gbps, or whether they are normally running.
In the case of 1Gbps iSCSI, the LEDs are not linkup when the link speed is not 1Gbps. Check
whether the transfer rate of the connected devices such as a host and switches is 1Gbps, or
whether they are normally running.
If the connected devices are normally running, check the cable connection.
