doubt about ora_priv res in sfrac

[sam321]

i m building sfrac 

following are steps i used to add ora_priv resourse to my configuration

-bash-3.00# haconf -makerw

-bash-3.00# hares -add ora_priv PrivNIC cvm

VCS NOTICE V-16-1-10242 Resource added. Enabled attribute must be set before agent monitors

-bash-3.00# hares -modify ora_priv Critical 0

-bash-3.00# hares -local ora_priv Device

-bash-3.00# hares -local ora_priv Address

-bash-3.00# hares -modify ora_priv Device -add bge2 0 -sys TEST1

-bash-3.00# hares -modify ora_priv Device -add bge3 1 -sys TEST1

-bash-3.00# hares -modify ora_priv Address 192.168.10.3 -sys TEST1

-bash-3.00# hares -modify ora_priv Device -add bge2 0 -sys TEST2

-bash-3.00# hares -modify ora_priv Device -add bge3 1 -sys TEST2

-bash-3.00# hares -modify ora_priv Address 192.168.10.5 -sys TEST2

-bash-3.00# hares -modify ora_priv NetMask 255.255.255.0

-bash-3.00# hares -modify ora_priv Enabled 1

-bash-3.00# haconf -dump -makero

bge2 and bge3 are my llt interfaces

after the configuration why it assigned the vip to one of llt interfaces???????????

am i going wron somewhere in concept

bge0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2

        inet 192.168.1.3 netmask ffffff00 broadcast 192.168.1.255

        ether 0:3:ba:c0:92:7d

bge2: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 3

        inet 192.168.2.2 netmask ffffff00 broadcast 192.168.2.255

        ether 0:3:ba:c0:92:7f

bge2:1: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 3

        inet 192.168.10.5 netmask ffffff00 broadcast 192.168.10.255

bge3: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 4

        inet 192.168.3.2 netmask ffffff00 broadcast 192.168.3.255

        ether 0:3:ba:c0:92:80

-bash-3.00# more /etc/hosts

#

# Internet host table

#

::1     localhost

127.0.0.1       localhost

192.168.1.3     TEST2   loghost

192.168.1.2     TEST1

192.168.2.1     TEST1-priv

192.168.2.2     TEST2-priv

192.168.10.3    TEST1-vip

192.168.10.5    TEST2-vip

i have not yet plumbed the interface where i want the vip to get assigned.Is it making the wron assignment of IP to one of llt interfaces as vip

Help me out guys

Hi Kuldeep,

you are defining bge2 & bge3 only as the interfaces while configuration, thats why it is taking that interface ..

-bash-3.00# hares -modify ora_priv Device -add bge2 0 -sys TEST1

-bash-3.00# hares -modify ora_priv Device -add bge3 1 -sys TEST1

PrivNIC resource would be needed to configure CRS IPs, & that by design happens on LLT interfaces only, see abstract below from SFRAC admin guide:

Configure Oracle private IP addresses under VCS PrivNIC or MultiPrivNIC to protect against link failures. This requires you to configure CRS private IP addresses and UDP cache fusion IP addresses on LLT interconnects.

Here is the reference section from guide, its under best practices:

one more thing Gaurav

whether both physical and virtual Ips assigned on bge2 on both nodes should be on same network???

in my case they are on diff network

[Gaurav_S · Accepted solution]

I believe that should't really matter, however there are considerations to it depending on how is connectivity made. If your servers are nearby & connected LLT are cross cables, would be simple /recommended to keep them in same network, however if server's lie little apart & you are using switches / vlans in between, it may happen that networks are different however it should still be able to ping.

In short, i would say, recommended would be same network..
