Adding (mapping) a Host LUN NOTE: When logical drives/logical volumes are first created, unless
Do Not Map was selected, host LUNs are automatically mapped after
logical drives/logical volumes have completed the initialization process. NOTE: On a SANnet II 200 SCSI array, you can create up to eight
logical drives with up to 32 partitions per logical drive. On a SANnet
II 100 Blade SCSI array, you can create up to six logical drives with
up to 32 partitions per logical drive. For both SCSI arrays, there is
a maximum of 128 LUN assignments, and a logical volume can be divided
into a maximum of 32 partitions. On a SANnet II 200 FC array, you can
create up to eight logical drives with up to 128 partitions per logical
drive.
All available LUNs are displayed under Partitions. For your
reference, Used LUNs displays a list of LUNs used for a specified
channel and Partition Assignment displays a list of channels,
IDs, and LUNs to which a partition has been assigned. NOTE: When a logical drive/logical volume is added or created,
it is assigned as either primary or secondary (controller assignment).
A logical drive/logical volume is then initialized and mapped to a primary
or secondary channel ID. If you unmap a logical drive/logical volume
and remap it to another host channel ID that has a different controller
assignment, you must reset the controller. If you unmap a logical
drive/logical volume and remap it to another host channel ID that has
the same controller assignment, you do not have to reset the
controller. If a logical drive/logical volume has remaining partitions
still mapped, the unmapped partitions can only be mapped to host channel
IDs of the same controller assignment.
To map multiple partitions (up to 32), select the first partition,
scroll to the last partition, and Shift-click to select everything in
between. Then click Assign Host LUN. As a result, Delete Host LUN becomes active.
NOTE: In the event that an error message is displayed when mapping
a host channel, repeat steps 1 through 5. Deleting a Host LUN
