Online Replacement of the A7173A Adapter

Online Addition and Replacement (OLAR for HP-UX 11i v1, or OL* for HP-UX 11i v2 and later HP-UX releases) enables you to add, replace, or delete a PCI host bus adapter in an HP-UX system without shutting down or rebooting the system, and without adversely affecting other system components. The system hardware uses slot-specific power control combined with HP-UX operating system support to enable this feature. For more information, see “Online Installation”.

	IMPORTANT: If the replacement A7173A adapter is new, meaning that it has never been installed, the mpt driver will continue to use the SCSI parameter settings that are already configured on the slot. If the A7173A adapter has been previously installed in a different slot or system, the SCSI parameter settings will not migrate to the new slot or system. In either case, it is still strongly recommended that the SCSI parameter settings be confirmed, and changed if necessary. See “Setting the SCSI Parameters” for details.
