Recommendations and further Informations
Since Serviceguard for RAC configurations may be complex to configure and maintain, it is
strongly recommended that you use Hewlett-Packard’s high availability consulting services
to ensure a smooth installation and rollout. Please contact your HP representative to inquire
about high availability consulting. In addition, you should work with your HP representative to
ensure that you have the latest firmware revisions for disk drives, disk controllers, LAN
controllers, and other hardware.
