Chapter 4 LUN Configuration
Caution Initiators have LUNs mapped starting from Map ID ‘0’. Failure to remap a LUN to Map ID ‘0’ will result
in LUN mapping issues.
Caution Deleting Map ID ‘0’ is not recommended. If it is deleted, all other LUNs mapped to this initiator group
might be lost from the Initiator sight. Also, while the next LUN mapping created will automatically be
assigned the Map ID ‘0’ but it would still not guarantee automatic rediscovery of the “lost” LUNs.
Note If a range of IDs for multiple LUNs is specified, a check for Map ID ‘0’ is first made and then the IDs
are assigned starting with the ID provided. If the number provided is already present, the starting Map
ID assigned will be incremental.
Note Map IDs from 0-255 are available for UNIX and Linux.
Note Map IDs 0-254 are available for Windows.
Step 5 Click Create or click Cancel to return to the Initiator’s Available LUN list.
The LUN appears in the Initiator’s LUN list.
Step 6 Repeat Steps 4 and 5 for each preferred available LUN.
Note To unmap a LUN, drag-and-drop it from the Initiator Group LUN list back to the Available LUNS list
or follow the Unmap procedure in this section.
Step 7 Click Back to Initiators to return to the Initiator Groups window.
Note The size of the Snapshot displayed during LUN mapping will be the same as that of its Origin LUN.
