Changing the SEP LUN

SEP LUNs allow access to SEPs. A SEP LUN may be set to a value of 0-7, SOFT, or NONE. If set to SOFT, the SEP LUN is automatically assigned a value when the controller boots. The soft LUN value will be assigned to the first available LUN (starting from zero) that does not already have a hard (that is, a numeric) LUN assignment. NONE means that the SEP cannot be accessed via a LUN.

Note that if both a controller LUN and a SEP LUN are set to SOFT, the controller LUN will be assigned a value first.

You may want to change the SEP LUN if it conflicts with the LUN of another device.

To change the SEP LUN:

1From the System Menu, select Configuration Menu and press Enter. The Configuration Menu screen displays.

2Select SEP Configuration and press Enter. The SEP Configuration screen displays.
