4.1.2.8.2 LUN Map
LUN, which stands for Logical Unit Number, is used to identify a logical unit in computer
storage. When creating an array, you may select Assign LUN automatically to
automatically assign a LUN to the new array. If Assign LUN automatically is not selected,
you need to assign the LUN manually using LUN map. If the slice has been partitioned,
you need to set its LUN Map.
Note
One slice can only be assigned one LUN.
Note
The ExaSAN RAID controller supports up to 64 LUNs.
1. Select the array to map by clicking on a drive with an array number.
2. Choose a LUN and from the drop down list select a slice to map to. Repeat for
multiple LUNs.
