I appreciate your response. If I has only one Private interface(LAN0) with one standby (LAN1) and Oracle Rac (126.96.36.199) is configured @ HPUX with SERVICEGUARD (HP CLUSTERWARE). HAIP is plumbed on that Private interface (LAN0) but if that LAN interface got failed then SERVICEGUARD will do the failover of all IPs plumbed or configured on
that Private interface(LAN0) to standby Interface (LAN1) except HAIP because Oracle don't use to plumb HAIP using SERVICEGUARD command so HAIP will be not failover to standby. If i don't have any other active private LAN interface HAIP failover from Oracle will not happen and due to that RAC instance went down. If we update RAC interconnect from HAIP to Real Private IPs and then disable HAIP then this type of scenario Serviceguard will do failover Real Private IPs into standby and inerconnect will work fine even HAIP is down, it will save from RAC failure.
HAIP will be good if I have multiple Active Private Interface, so i case of fail of one interface HAIP will be transparently moved to other active private lan interface by Oracle Grid (188.8.131.52).
Disable HAIP will be goof if I have only one interface with one standby , so i case of fail of one interface HAIP will not be moved by Oracle Grid (184.108.40.206) because there is not other active private interface, so in this case ServiceGuard can do the Failover job from active lan to standby.
this is a question on how the integration between third party clusterware and Oracle clusterware is done.
E.g. in the space of Solaris Cluster to get this working, the integration disables the HAIP at the moment, till the integration solves a similar issue you describe.
Regarding HP Service Guard, I expect something similar. At least I expect that HP and Oracle get this functionality working together - whether you only have one interface or multiple.
However I always try to avoid third party clusterware whereever possible ;)
Hello, I too have the similar issue now.Just configured the RAC in 220.127.116.11 and the 169.254/16 is causing an issue.We have the same IP Range used for backups and what Oracle does is , it diables the backups range and uses 169.. for the Private IP redundancy.
Is there any way i can disable the HAIP, so that i can move smoothly towards the backup also.
