LUN Configuration

The LUNs List, page 4-1

Initiator Groups, page 4-6

Each Logical Unit Number (LUN) identifies a specific logical unit, which may be part of a drive, an 
entire drive or several drives in a storage array. A LUN, then, can reference an entire RAID set, a single 
drive or multiple drives. In any case, the logical unit is treated as if it is a single device and is identified 
by the LUN.

Once the initial 

Cisco UCS Invicta C3124SA Appliance

 

setup has been completed, LUNs can be created 

and configured from the LUN Configuration window using buttons and right-click menus. The 
Administrator must determine the best LUN configuration.

The following section describes LUN Configuration tasks.

Note

Only those who were assigned roles with the associated permissions can view and/or access these tasks.

The LUNs List

The list of LUNs has check boxes adjacent to them. These check boxes can be used for selecting an 
unlimited number of LUNs for deletion. 
Check boxes can also be used for selecting and viewing the performance of up to the first 5 selected LUNs. 
All columns are sortable.

Create LUN

The 

LUNs

 window appears.

Step 2
