Migration of HP-UX 11i V2
The HP-UX 11i V2 standalone hosts can be migrated using the online migration procedure. However,
after zoning in the destination array to your standalone host(s), the new paths /Physical
Volumes (PVs) need to be added to your Volume Group /PVLinksconfiguration using the
vgextend command before removing the paths to the source array as shown in step 13 below.
The vgdisplay command can be used to confirm that the PVLinks configuration.
A Serviceguard cluster with HP-UX 11i V2 hosts can also be migrated using the online migration
procedure, but if shared volume groups using SLVM (Shared Logical Volume Manager) are used,
then some additional configuration steps are required. The shared volume group does not
automatically recognize new paths to the volume exported through the destination. SLVM SNOR
(Single Node Online Re-configuration) operation can be used to change the configuration of a
shared volume group, while keeping it active in only a single node. Using the SNOR procedure,
a minimum of one application node is available during the volume group re-configuration.
