We eventually ditched RAC and are now completing a hpux to linux migration. When we were running rac on hpux service guard and raw worked well for us ( no veritas licenses ). At some point hp and so hpux started bundling in part of the veritas cluster software with service guard ... but that happened after we were headed in a different direction.
With all the attention on the quality of oracle support *cough cough* there is no shortage of people wondering if it would not be better to avoid having your database vendor also provide your clustering software but of course oracle prevents that at the 10g level and above.
