HP StorageWorks 1500cs Modular Smart Array - Manual (Page 39)

Scripting in ACU 39
In Reconfigure mode, the default setting is the existing stripe size for the specified logical drive. If you
specify a stripe size that is different from the existing value, then ACU attempts to migrate the logical drive
to the stripe size that you specify.
CAUTION: Back up all data before extending a logical drive.
ArrayAccelerator
This option specifies whether the array accelerator is enabled or disabled for the specified logical drive.
The default value is Enabled.
LogicalDriveSSPState
This option is valid only for controllers that enable SSP on a logical drive basis (at present, this applies
only to the RA4x00). Other controllers that support SSP use the SSPState option ("
SSPState " on page 36 ).
• For new logical drives, the default value is Disabled.
• For existing logical drives, the default value is the current logical drive setting.
SSPAdaptersWithAccess
Enter values here to identify the SSP adapters that you want to have access to a logical drive. The values
are processed only if either SSPState or LogicalDriveSSPState is set to Enable. Otherwise, the values are
ignored.
NOTE: Be sure that every HBA in the system has access to the logical drives for which multi-path will be
used.
PreferredPath
If you select the Manual setting for PreferredPathMode (on page 36 ), use the PreferredPath
command to specify the path for I/O to the logical drive on a redundant controller in active/active mode.
The default setting for this option is 1. With this setting, the controller in chassis slot 1 is the preferred
controller for I/O to the logical drive. If you select 2, the controller in chassis slot 2 becomes the preferred
controller for the logical drive.
To determine the chassis slot numbers, use the
show
command on a controller that supports redundant
controllers.
HBA_WW_ID
This option specifies which HBA to apply the configuration changes to using the HBA's assigned WWN.
ConnectionName
This option is a user-defined string used as the connection name for the specified HBA.
The string can consist of:
• A maximum of 16 characters
• Embedded space characters but cannot end with a space character
• Any of the following characters: a–z, A–Z, 0–9, !, @, #, *, (, ), -, _, +, :, ., /, and [space]
