Unable to start scan listener

Question

Hi,
Some application users reported that they are unable to connect to the database.
Getting this err r : ORA-12505: TNS:listener does not currently know of SID given in connect
checked and found that the database listener was running from old home.(recently clusterware was upgraded from 11g to 12c)
Started the DB listener from grid home.
Then found that scan listener is not running.
While starting scan listener, getting below error.
crsctl start resource ora.LISTENER_SCAN1.lsnr
CRS-2644: No hosting members of 'ora.LISTENER_SCAN1.lsnr' are either online or are allowed to be used by the resource
CRS-4000: Command Start failed, or completed with errors.

Answer 1

is database not registered with SCAN? why are you having two different listeners db listener and scan? Do you mean to say local listener on server?
Trying running below commands as grid user ,
this is how it worked with me
(commented out the names and ipaddresses)
~>+ASM1@xxxxx:/home/grid~> srvctl config scan
SCAN name: test-scan, Network: 1/192.xxx.xxx.x/255.xxx.xxx.x/bond0
SCAN VIP name: scan1, IP: /test-scan.xxxx.nc/192.xxx.xxx.101
SCAN VIP name: scan2, IP: /test-scan.xxxx.nc/192.xxx.xxx.102
SCAN VIP name: scan3, IP: /test-scan.xxxxx..nc/192.xxx.xxx.100
~>+ASM1@xxxxx:/home/grid~> srvctl config listener
Name: LISTENER
Network: 1, Owner: grid
Home: <CRS home>
End points: TCP:1521
~>+ASM1@xxxxx:/home/grid~>  srvctl config scan_listener
SCAN Listener LISTENER_SCAN1 exists. Port: TCP:1521
SCAN Listener LISTENER_SCAN2 exists. Port: TCP:1521
SCAN Listener LISTENER_SCAN3 exists. Port: TCP:1521
to start and stop listeners
~>+ASM1@xxxxx:/home/grid~>  srvctl stop listener
~>+ASM1@xxxxx:/home/grid~>  srvctl start listener
~>+ASM1@xxxxx:/home/grid~> srvctl stop scan_listener
~>+ASM1@xxxxx:/home/grid~> srvctl start scan_listener
Thanks
