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).
