4. Select the location of the storage for the LU.

The storage can be from a physical device or storage pool (composed of one or more

physical devices) or, for systems with external storage, from raw devices available to

the iSCSI Feature Pack.

If you need to modify your RAID system to allocate additional space for your LU, click

the link Click here to add raid set. Afterwards, click Click here to force a rescan of

the devices.

5. Enter a Size for the LU.

The minimum size for each LU is 20 MB.

6. Assign one or more hosts to the newly created LU and assign access rights for each.

No Access - This host cannot access this LU.

•

Read Only - This host will have read-only access to the LU.

•

NOTE: If you set Read Only access rights for a LU that contains an NTFS partition, that partition

will only be readable in Windows 2003. The LU will not show up properly in Windows

versions prior to 2003.

•

Read/Write Exclusive- Only this host can access the LU. The host has both read

and write access. All others (including Read Only) will be denied access.

•

Read/Write Non-Exclusive - Two hosts can connect at the same time with both

read and write access.

NOTICE: There is a potential for data corruption if you set the access rights to Read/Write Non-

Exclusive and you have multiple hosts writing to a device at the same time.

7. Confirm all information and click Finish to create the LU.

NOTE: In order for a host to use the newly created LU, you will have to take operating system-

specific actions in order for the host to see the new storage. For example, with Windows

you must rescan disks via the system's Computer Management (available through the

Control Panel). You will then need to write a signature, create a partition, and format the

drive so that the host can use it.
