Mapping Volumes to a Server
• By default, Storage Center uses a different LUN if the specified LUN is already in use.
To use the next available LUN, check Use Next Available LUN. If you do not want to
use a different LUN when the specified LUN is already in use, clear the Use Next
Available LUN checkbox.
Restricting Mapping Paths
These options will only appear when mapping to a server with multiple server HBA ports,
when mapping a server on a cluster Storage Center, or when mapping a virtual server to a
volume.
The options that appear depends on the type of server to which you are mapping this
volume:
• Server with HBA ports of different transport types (such as Fibre Channel and iSCSI):
Select Transport option appears. Check to map to only one of the transport types.
Select the transport type.
• Server with multiple server HBA ports: Select Specify Server Ports. Select the ports to
be used.
• Map to Controller: To map to a specific controller, check Map to Controller. Select a
controller.
• Map to host: Select Host, Virtual, or Both.
Configuring Multipathing
If the operating system of a server does not support multipathing, this option will not be
shown.
• Select the maximum number of paths used to map the selected volume to the server.
The maximum number of paths allowed may be limited by the operating system of the
server.
