Oracle RAC Error: CRS-2805: Unable to start 'ora.LISTENER.lsnr' because it has a 'hard' dependency on resource type 'ora.cluster_vip_net2.type' and no resource of that type can satisfy the dependency_part1

Issue :- 
LISTENER is not running on one of RAC node. After attempting to restart throws below error.

[ora12c@RAC2 ~]$ srvctl start listener -n RAC2
PRCR-1013 : Failed to start resource ora.LISTENER.lsnr
PRCR-1064 : Failed to start resource ora.LISTENER.lsnr on node RAC2
CRS-2805: Unable to start 'ora.LISTENER.lsnr' because it has a 'hard' dependency on resource type 'ora.cluster_vip_net1.type' and no resource of that type can satisfy the dependency
CRS-2525: All instances of the resource 'ora.RAC1.vip' are already running; relocate is not allowed because the force option was not specified


Solution :-

Step 1 :- Do pre check list.

[ora12c@RAC2 ~]$ crsctl status res -t

In one of RAC setup , process ora.LISTENER.lsnr was in OFFLINE state. When I tried to start it throws an subjected error and LISTENER did not come up.

Its good to check for other cluster important process

[ora12c@RAC2 ~]$ crsctl check cluster -all
**************************************************************
RAC1:
CRS-4537: Cluster Ready Services is online
CRS-4529: Cluster Synchronization Services is online
CRS-4533: Event Manager is online
**************************************************************
RAC2:
CRS-4537: Cluster Ready Services is online
CRS-4529: Cluster Synchronization Services is online
CRS-4533: Event Manager is online
**************************************************************

CSS,CRS,EVM seems to be fine.

Step 2 :-  Check are you able to ping VIP from both nodes

                                            Ping RAC1 virtual IP

[ora12c@RAC1 ~]$ ping RAC1-vip

PING RAC1 (RAC1) 56(84) bytes of data.
64 bytes from RAC1: icmp_seq=1 ttl=63 time=0.378 ms
64 bytes from RAC1: icmp_seq=2 ttl=63 time=0.313 ms
64 bytes from RAC1: icmp_seq=3 ttl=63 time=0.334 ms
64 bytes from RAC1: icmp_seq=4 ttl=63 time=0.438 ms
64 bytes from RAC1: icmp_seq=5 ttl=63 time=0.377 ms
^C
--- RAC1 ping statistics ---
5 packets transmitted, 5 received, 0% packet loss, time 3999ms
rtt min/avg/max/mdev = 0.313/0.368/0.438/0.043 ms

------------------------------------------------------------------------------------------------

                                             Ping RAC2 virtual IP

[ora12c@RAC1 ~]$ ping RAC2-vip

PING RAC2 (RAC2) 56(84) bytes of data.

Destination host unreachable.
Destination host unreachable.
Destination host unreachable.
Destination host unreachable.

This seems to be an issue.

Step 3 :- After doing some R&D , I found that VIP of RAC2 is not registered with CRS due to which LISTENER on RAC2 is not coming up.

Run srvctl config nodeapps -a to check both VIP's is registered or not

[ora12c@RAC2 ~]$ srvctl config nodeapps -a
Network 1 exists
Subnet IPv4: *.*.*.0/255.255.255.0/eno167832, static
Subnet IPv6:
Ping Targets:
Network is enabled
Network is individually enabled on nodes:
Network is individually disabled on nodes:
VIP exists: network number 1, hosting node RAC1
VIP Name: RAC1-vip.co.in
VIP IPv4 Address: *.*.*.*
VIP IPv6 Address:
VIP is enabled.
VIP is individually enabled on nodes:
VIP is individually disabled on nodes:

Above out put shows that only RAC1 vip is registered with CRS. It means we need to register RAC2 vip in CRS.

Step 4 :- Run as root
Go to Grid path ----> bin

[root@RAC1 ~]# cd /rdbms/app/12.1.0.2/grid/bin
[root@RAC1 bin]# ./srvctl add vip -n RAC2 -A RAC2-vip/255.255.255.0/eno167832 -k 2

Now both the VIPs are registered.


Run again srvctl config nodeapps -a to check both VIP's is registered or not

[root@rac1 bin]# ./srvctl config nodeapps -a

Network 1 exists
Subnet IPv4: *.*.*.0/255.255.255.0/eno167832, static
Subnet IPv6:
Ping Targets:
Network is enabled
Network is individually enabled on nodes:
Network is individually disabled on nodes:
VIP exists: network number 1, hosting node RAC1
VIP Name: RAC1-vip.co.in
VIP IPv4 Address: *.*.*.*
VIP IPv6 Address:
VIP is enabled.
VIP is individually enabled on nodes:
VIP is individually disabled on nodes:
VIP exists: network number 1, hosting node RAC2
VIP Name: RAC2-vip.co.in
VIP IPv4 Address: *.*.*.*
VIP IPv6 Address:
VIP is enabled.
VIP is individually enabled on nodes:
VIP is individually disabled on nodes:

Step 5 :- Start RAC2-vip
Attempting to start `ora.RAC2.vip` on member `RAC2`
Start of `ora.RAC2.vip` on member `RAC2` succeeded.
Attempting to start `ora.LISTENER.lsnr` on member `RAC2`

Start of `ora.LISTENER.lsnr` on member `RAC2` succeeded.

Now the both nodes VIP is registered and it is reachable.

Step 6:- Check the status again (Step 1 commands)

[ora12c@RAC2 ~]$ crsctl status res -t
