LUN Mapping Parameters
• Initiator – The Fibre Channel or iSCSI card in the Host system that initiates
commands to the target (VTrak).
• Logical Drive ID – This is actually the disk array ID number.
• RAID Level – RAID Level of the logical drive.
• Capacity – Capacity of the logical drive.
• Serial Number – Serial number of the logical drive.
• WWN – World Wide Name, used for the Initiator name.
A Fibre Channel initiator name is the World Wide Port Name of the device
and is composed of a series of eight, two-digit hexadecimal numbers.
An iSCSI initiator name is the iSCSI name of the initiator device and is
composed of a single text string. iSCSI WWNs are somewhat different from
regular WWNs.
• LUN – Logical Unit Number on this logical drive for the selected initiator.
You must enter different LUN numbers for each logical drive.
LUN Map – SCSI
The Storage Services–LUN Map tab displays the Target IDs and LUNs assigned
to each logical drive.
For SCSI, LUN Mapping is the process of applying a LUN Map so that each
channel can access the logical drive (target).
