To add a 32-bit LUN that will not exceed 2 TB, type:          

<Enter>

 

To add a 64-bit LUN, that exceeds 2 TB:   

<Enter>

For both cases,  “X” is the Logical Unit with a range of <0..1023>. 

For either case, the system prompts you for all the necessary information to create the LUN and indicates 
if the LUN was successfully added to the system. 

The required LUN information includes: 

• Capacity (in MBytes) - default is to use all available capacity

• Number of tiers - default is to use all tiers 

• Block size (in Bytes) - default is 512Bytes 

• Label - may contain up to 12 characters 

A LUN must be formatted before it can be used. 

To format a LUN, use LUN FORMAT. Specify the LUN <0..1023> when prompted. This performs a 
destructive initialization on the specified LUN by over-writing all the data on the LUN with zeroes. 

The rate of format can be adjusted using the DELAY and EXTENT parameters of the LUN command. 

If you need to interrupt a format operation, for any reason, use these commands: 

• LUN PAUSE pauses the current format operations. 

• LUN RESUME releases the paused format operations.

• LUN STOP aborts all the current format operations. 

To change the label of a LUN:

Type:

 

 

<Enter>. 

Select the LUN to change <0..1023>  and press Enter.

Type in the new label and press Enter. A LUN label may contain up to 12 characters (Figure 3–24).
