Hello,
I'm planning what in subject.
Actually both my public and private interconnects are on bonding devices, so that I have
[grid@racsvi1 ~]$ oifcfg getif -global
bond1 10.10.8.0 global cluster_interconnect,asm
bond0.65 10.4.4.0 global public
[grid@racsvi1 ~]$
with
eth2 and eth3 part of bond0
eth4 and eth5 part of bond1
Now, due to infrastructure changes I have to swap the 2 interfaces used for intracluster bond1 with the 2 interfaces used for public bond0.
So at the end of the change, from OS point of view still the public bond will be bond0 (with bond0.65 vlan for Oracle Rac public nad same ip) but composed of eth4 and eth5, and the private will still be bond1, but insisting on eth2 and eth3.
Can you confirm that the change will be transparent as neither interface name (bondX) nor ip addresses will change?
Or will I have to do anything before?
I'm asking also because on a virtual rac where instead I have single interface configuration and I'm simulating the swap, I have problems starting CRS.
so initially eth0 for public and eth1 for private and swap the interface names.
I have read these docs:
How to Modify Public Network Information including VIP in Oracle Clusterware (Doc ID 276434.1)
How to Modify Private Network Information in Oracle Clusterware (Doc ID 283684.1)
that suggest to first add the new interface (even if not present) with cluster active and then delete after changing os parameters.
But this seems feasible for new/different interfaces, and not when you have to swap them..... because at the initial stage I would have for example eth1 both part of public and private Oracle networks....
any hint in this scenario where you have eth0 for public and eth1 for private and you want to swap them (the ip addresses will remain he same: hostname/ip of nodes the same as before, but attached to eth1 interface name and not eth0) ?
Thanks in advance,
Gianluca
