I am planning to install 126.96.36.199 Grid Infrastructure on a Solaris platform , We used to do IPMP before for High availability interconnect.
since 188.8.131.52 Oracle seems to address it this by itself but I am having a hard time finding documentation,
I am trying to figure out what I need to request the network admin and SA to be able to start the install.
We use VLAN for interconnects, so for HAIP I need multiple VLANS and have interfaces created for those by the SA's so that I can use at the "Network Interface Usage" stage of GI install ?
I found following online about this but kind of confused, it talk about having 2 interfaces , This example shows eth1 and eth2 using a 192.168.0.* subnet. But shouldn't they supposed to be on different subnets , rather then same subnet ?
"Oracle does not recommend setting the CLUSTER_INTERCONNECTS parameter, which overrides the default interconnect settings at the operating system level. Instead, *the best practice is to use operating system bonding techniques* (also referred to as NIC (network interface card) bonding)" - Oracle® Real Application Clusters Administration and Deployment Guide 11g Release 2 (11.2) E16795-13
*Solaris IPMP and Trunking for the cluster interconnect in Oracle Grid Infrastructure 11g Rel. 2 [ID 1069584.1]*
184.108.40.206 and above
Started from 220.127.116.11, as Redundant Interconnect is supported natively by Oracle Clusterware, it's not recommended to configure IPMP for cluster interconnect anymore; please refer to note 1210883.1 for more details.
But the note *1210883.1* have a huge list of bug, you must be aware of list of bug of HAIP before choose this option:
11gR2 Grid Infrastructure Redundant Interconnect and ora.cluster_interconnect.haip [ID 1210883.1]
I never used HAIP, then I'm suspect to give my opinion. I always use bound of interface at OS level I consider more simple to manage and is more mature.
