The situation :
There is an Oracle GI 12.2 on two nodes.
We successfully added new public and administrative networks to all nodes (created vips, scan, scan_listeners etc.).
We migrated all resources to it (database and asm instances).
We need to stop clean up all TCP/IP addresses of the network 1 (default client's network used during GI installation).
So, you need to do the following :
1. Stop all and remove all listener(s) of network 1
2. Stop and remove scan resources of network 1
3. Stop and remove vips of network 1 (this will require higher privileges)
4. Stop network 1 (this will require higher privileges and you'll have to stop dependent resources)
5. Remove network 1
At the step 4 you can encounter into errors like :
- CRS-2730: Resource 'ora.qosmserver' depends on resource 'ora.net1.network' ;
- CRS-2730: Resource 'ora.ons' depends on resource 'ora.net1.network';
- CRS-2730: Resource 'ora.cvu' depends on resource 'ora.net1.network'
Use the following to reassign Grid dependencies to other network (network 2). Use it with caution (they are unsupported by Oracle).
# crsctl modify resource ora.ons -attr "START_DEPENDENCIES=hard(ora.net2.network) pullup(ora.net2.network)" -unsupported
# crsctl modify resource ora.ons -attr "STOP_DEPENDENCIES=hard(intermediate:ora.net2.network)" -unsupported
# crsctl modify resource ora.cvu -attr "START_DEPENDENCIES=hard(ora.net2.network) pullup(ora.net2.network)" -unsupported
# crsctl modify resource ora.cvu -attr "STOP_DEPENDENCIES=hard(intermediate:ora.net2.network)" -unsupported
# crsctl modify resource ora.qosmserver -attr "STOP_DEPENDENCIES=hard(intermediate:ora.net2.network)" -unsupported
# crsctl modify resource ora.qosmserver -attr "START_DEPENDENCIES=hard(ora.net2.network) pullup(ora.net2.network)" -unsupported
Final statement will be successful :
# srvctl remove network -netnum 1
Aftermath run early stopped resources (if needed) :
$ onsctl start
$ srvctl start cvu
$ srvctl start qosmserver
Check that everything works.
Good Luck !
