Procedure
1. In the web interface system tree, right-click the Logical Units tree node and select Create. The logical
unit creation wizard opens.
2. After you read the overview, click the Next button to set the logical unit parameters.
3. The parameters available for the logical unit follow.
Name This setting is a user-defined name for the logical unit to make it easily identifiable.
Number
This setting is the logical unit number (LUN) that is presented to the host.
Size This setting is the size of the logical unit.
Device ID
This setting is an OpenVMS specific identifier.
Sector Size
This setting is the sector size of the logical unit.
Offset This setting sets the logical unit starting alignment to offset.
Report corrected media errors to the SCSI host
This setting controls whether any internal corrected errors are reported over the SCSI layer to
the host. For most environments, enable this setting.
Report uncorrected media errors to the SCSI host
This setting controls whether any internal uncorrected errors are reported over the SCSI layer
to the host. For most environments, enable this setting.
Enable ACA Support
This setting enables Auto Contingent Allegiance (ACA) support for the logical unit. Some host
systems, such as systems that are running the AIX
®
operating system, require this setting to
run multiple concurrent commands. After this option is changed, all interface ports that have
access to the logical unit must be reset.
4. After you set the appropriate values, click Next. A final pane confirms the values. After you click
Finish, the logical unit is created.
Results
For the logical unit to be used, you must define an access policy.
Logical unit access policies
You can use the web interface to create access lists for individual Fibre Channel or InfiniBand ports.
This access list allows the administrator to specify which ports are allowed to communicate with each
logical unit.
New logical units are displayed with a warning state that notifies the administrator that a logical unit
was created. The logical units are not presented to any hosts until an access policy is defined.
Adding an access policy to a logical unit
To make logical units accessible to connected servers, you must first link the logical unit to the storage
system Fibre Channel or InfiniBand ports
About this task
To add an access policy to a new logical unit, complete the following steps:
