HP Microsoft Windows Server 2003 for Itanium-based Systems Error reporting, SSPAdaptersWithAccess

Page 39

•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.

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]

HostMode

This option specifies the HostMode for a selected HBA. Setting the Host Mode optimizes the storage array for the selected operating system. The available host modes for an HBA are device-specific. Not all modes are available on all devices. Not all HBAs support a HostMode.

The following operating system options might be available:

•Default

•Microsoft® Windows®

•OpenVMS

•Tru64

•Linux

•Solaris

•Netware

•HP-UX

Error reporting

Any errors that are encountered during ACU scripting are logged to ERROR.INI. This error file describes the error and if possible indicates the controller, array, and logical drive that are associated with the error.

The error reporting in ACU scripting is not as specific as the error reporting in the ACU GUI. Instead, it is designed to give an advanced user enough information to understand what went wrong so that they can correct the problem and continue. Some of the possible error messages are listed in the table.
