Remove RAID
and
confirm the operation in the following confirmation dialog.
4.3 iSCSI Space Allocation
The MaxNAS R8 has the ability to create special volumes for use via iSCSI. iSCSI volumes are
logical block devices that appear to an attached host as if they were locally attached SCSI
devices- For more information regarding iSCSI please visit the Internet Engineering Task Force
(IETF) at http://tools.ietf.org/html/rfc3720. You may create, modify and delete existing iSCSI
target volumes by navigating to “Storage” -> “Space Allocation”
4.3.1 Creating an iSCSI volume
The following steps describe the procedure to create and allocate space to an iSCSI volume:
1. Select the RAID set you
wish to use from the
drop-down field at the
top (circled above.)
2. Click
in the
iSCSI Target tab under
Volume Allocation List.
3. Assign a capacity to
the volume.
4. Select “Enable” under
iSCSI Target Volume
(You can also enable a volume in the future should you
wish to create the volume for future use)
5. Assign a target name. This name will used as a part of
the iSCSI Qualified name (IQN)- The MaxNAS R8 will
create the IQN based target name, month and year, and LUN ID specified.iSCSI Qualified
Names follow a iqn.yyyy-mm.{reversed domain name} nomenclature (e.g. iqn.2001-04.com.
acme:storage.tape.sys1.xyz). iSCSI Target Names must be unique and can contain only
lower case and numeric characters.
6. Set the current year and month.
7. Set a unique LUN ID. Each iSCSI volume on the MaxNAS R8 must have a unique LUN ID
number. The menu will automatically increment the LUN ID for each new volume created.
8. If you wish to enable CHAP authentication you can do so under “Authentication” and
assign a user name and password here. CHAP (Challenge Handshake Authentication
Protocol) is a standard security mechanism used by iSCSI to ensure authenticated access
between host and target.
9. Click
OK
to save any settings changes here.
4.3.2 Modify an existing iSCSI Volume.
To modify an existing iSCSI volume, select the volume you wish to modify and click
in the top-bar. The Modify menu is very similar to the create menu, except that some menu
items are unavailable. You can also go to this menu after a target volume has been created
Note: The MaxNAS R8 supports
up to 5 iSCSI volumes.
