Modifying the controller chassis name
If a controller is configured with at least one logical drive, you can assign the controller a simplified name
(the chassis name) to make it easier to identify and enter the correct controller in a command.
Syntax:
<target> modify ch="new chassis name"
where <target> is a controller.
Example commands:
=> ctrl sn=P56350D9IP903J modify ch="Lab 6"
=> ctrl ch="Lab 4" modify ch="Lab 6"
Using Selective Storage Presentation
SSP (also known as Access Control List commands) enables you to specify which host controllers are to
have access to particular logical drives. This feature prevents data corruption that can occur when
different servers using different operating systems access the same data.
Using SSP requires two commands:
• The first command activates the SSP feature on the controller.
• The second command specifies the logical drives that need access control. This command also
specifies the adapter IDs or the connection names that are to be allowed or denied access to the
logical drives.
Activating SSP on a controller can be thought of as modifying the controller access to the SSP feature. The
standard syntax for this operation is thus:
<target> modify ssp=on|off [forced]
where <target> in most cases is the controller itself, but for an RA4x00, it is a logical drive on the
controller.
When you first activate SSP on a controller or logical drive, the logical drives are inaccessible to all
adapter IDs by default. The adapter IDs are said to be masked. Because masking prevents access to the
logical drives, the CLI normally displays a warning prompt when you enter the command to activate SSP.
To prevent the prompt from appearing (when using this command in a batch file script, for example), add
the
forced parameter.
After you have activated SSP, unmask devices by either their adapter IDs or their connection names using
the following syntax:
<target> modify mask|unmask=#,#,...|all [forced]
where
<target>
is a logical drive.
Example commands:
=> ctrl ch="Lab 3" modify ssp=on forced
=> ctrl ch="Lab 4" ld 1 modify mask=210000E08B07A68F
=> ctrl ch="Lab 4" ld all modify unmask="cnxn 3","cnxn 4"
Sample scenario
First, check the SSP status of the controller:
