NOTE:
1. For support details for interfamily online migration of Integrity VM guests, see Section 5.7.2.4
(page 41).
2. Interfamily online migration of Integrity VM guests has introduced a new HP-UX kernel tunable
named mdep_reduce_rse_size on VSPs using Intel® Itanium® 9500 processors. For more
information about combinations of values for mdep_reduce_rse_size supported for online
migration of Integrity VM guests when both source and destination VSPs use Intel® Itanium®
9500 processors, see Table 7 (page 42).
5.7.2.4 Interfamily online migration of Integrity VM guests
The capability to do online migration of Integrity VM guests between VSPs using processors
belonging to different processor families is referred to as Interfamily migration.
Starting with HP-UX vPars and Integrity VM V6.3, online forward and fallback migration of Integrity
VM guests between VSPs using Intel® Itanium® 9300 at one end and Intel® Itanium® 9500 at
the other end is supported. Other processor combinations are not supported.
Interfamily online migration is supported only if all the following conditions are satisfied:
• Supported combinations of HP-UX kernel tunable on the VSP
Online migration of Integrity VM guests between VSPs with either Intel® Itanium® 9300 or
9500 processors is supported only for combinations of the HP-UX kernel tunable
mdep_reduce_rse_size set on the VSPs, as given Table 7 (page 42).
