54 Chapter 4: Manage Storage Space
Manage iSCSI LUNs with Storage Manager
Go to Main Menu > Storage Manager and click the iSCSI LUN tab to manage iSCSI LUNs on your
Synology DiskStation. An iSCSI LUN (logical unit number) can be mapped to multiple iSCSI Targets to perform
storage operations such as read or write. You can create up to 10 or 2561
iSCSI LUNs on your DiskStation.
There are 2 ways to create an iSCSI LUN:
Designate several disks (Block-level).
Designate a portion of your volume space (Regular Files).
If you create an iSCSI LUN with several disks, you can repair or expand it, or change its RAID type, just like using
a volume. (Please see Page 44 of this chapter for detailed information about volume management.)
To create an iSCSI LUN:
1 Click Create.
2 Select Cu stom.
3 Click Next.
4 Select the iSCSI LUN type you want to create.
iSCSI LUN (Regular Files): The iSCSI LUN is created by designating a portion of the volume space for its
usage. Set up iSCSI LUN configuration, including Name, Location, Thin Provisioning, Capacity (GB),
iSCSI Target mapping.
iSCSI LUN (Block-Level) - Single LUN on RAID: The iSCSI LUN is created by combining several hard
disks. Enter the name for the LUN, choose iSCSI Target mapping and click Next. You can create and
manage the LUN just like working with a volume. See "Create a Volume by Combining Several Hard Disks"
on Page 46 for more information about volume creation.
iSCSI LUN (Block-Level) - Multiple LUN on RAID: The iSCSI LUN is created by allocating partial space on
a Disk Group. Enter the name for the LUN, choose iSCSI Target mapping and click Next. You can create
and manage the LUN just like working with a volume. You can repair or expand it, or change its RAID type,
just like using a volume. See "Create a Volume by Allocating Partial Space on a Disk Group" on Page 46 for
more information about volume creation.
