24 LUN Manager for the XP128/XP1024
• iSCSI name: (Mandatory). You must assign iSCSI names to iSCSI ports. iSCSI names are used to
uniquely identify each iSCSI node. iSCSI nodes are devices that use the iSCSI protocol for
communication, such as iSCSI ports in the disk array, host bus adapters in host servers, and switching
hubs for network relaying.
iSCSI names must be specified in one of the following formats:
• eui format:
An IEEE 64-bit Extended Unique Identifier is used to specify the iSCSI name. The iSCSI name begins
with eui., which is followed by a WWN (world wide name) of an iSCSI port.
If a host is connected to an iSCSI port, LUN Manager automatically displays the iSCSI name in eui
format.
Example:
EUI .02004567A425678D
• iqn format:
The iSCSI Qualified Name format is used to specify an iSCSI name. For information on specifying
iSCSI names in this format, refer to iSCSI-related documentation.
Example: iqn.2003.09.com.hp:iscsi-r450:model-xxx:sn-xxxxxx:lun00
The length of an iSCSI name must be exactly 20 characters in eui format, and up to 223 characters in
iqn format. iSCSI names can include letters, numbers, periods (.), hyphens (-), and colons (:), but they
cannot include double-byte characters. iSCSI names are not case-sensitive.
• iSCSI alias: (Optional). An iSCSI alias is a nickname you can assign to an iSCSI name. iSCSI aliases
are helpful for managing and identifying iSCSI ports.
It can be difficult to identify iSCSI ports by iSCSI names because an iSCSI name contains many
characters and can be difficult to remember. Assigning a short, easy-to-remember iSCSI alias allows
you to identify iSCSI ports easily and quickly.
An iSCSI alias can contain up to 32 characters. iSCSI aliases can include letters, numbers, periods (.),
hyphens (-), and colons (:), and cannot include double-byte characters. iSCSI aliases are case sensitive;
for example, MyPort and myport are different iSCSI aliases.
• Port number: (Mandatory). LUN Manager allows you to specify a port number as an integer from 1 to
65535. The initial value of a port number is 3260.
• Keep-alive timer: (Mandatory). This timer is used when there is a connection between an iSCSI port
and another iSCSI node. For example, if the keep-alive timer is set to 60 seconds, the disk array checks
whether a communication packet was sent between an iSCSI port and another iSCSI node (such as a
host bus adapter or a switching hub) every 60 seconds.
You can specify a value from 0 to 64800 seconds. The initial value for the keep-alive timer is 60
seconds.
• Whether to register iSCSI ports in iSNS servers: The iSNS server is a server computer on which an
Internet Storage Name Service (iSNS) service is installed. This server is used to manage IP addresses
and iSCSI names of iSCSI ports. Using iSNS servers is optional. If iSNS servers are configured and
used, iSCSI ports are easily discovered and managed.
NOTE: For detailed information about configuring iSNS servers, see the iSNS-related
documentation.
• IP address of iSNS server: To use an iSNS server, specify the IP address of the iSNS server.
• TCP port number of iSNS server: To use an iSNS server, specify a TCP port number of the iSNS server.
NOTE: Specify 3205 as the TCP port number if you use Microsoft ® iSNS Server as the iSNS
server. If you specify other than 3205, you cannot register iSCSI ports in iSNS server.
Checking the status of the connection between hosts and the disk subsystem
Use LUN Manager to issue a ping command from an XP128/XP1024 iSCSI port to a host. The ping
command checks whether the host and the XP128/XP1024 can communicate with each other. If the host
