•
Read/Write Exclusive
- Only one host can access this LU at a time. 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.
NOTE:
If you do not assign any LUs to this host, after the host is created, the
Status
field will
display
Not Connected
.
8. Confirm all information and click
Finish
to create the host.
The
Status
field will display
Connected
if the host is assigned at least one 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.
Managing Host Initiators
The iSCSI Feature Pack can use an iSNS Server from any iSCSI Feature Pack to locate
existing iSCSI initiators. However, each initiator can only be associated with a single host.
To add or delete initiators for a host:
1. On the
Host
screen, click the checkbox to the left of the host that you want to manage.
2. Click
Initiators
.
A list of existing initiators for this host is displayed along with any iSCSI initiator alias.
3. To add a new initiator, click
Add.
You can then select from the automatically discovered initiators or you can manually
enter initiators.
4. To delete an initiator, click the checkbox to the left of it and click
Remove
.
Managing the LUs Assigned to a Host
To change a host’s LU assignments or access rights:
1. On the
Host
screen, click the checkbox to the left of the host whose assignment you
want to change.
2. Click
Logical Units
.
