I have RAC 19c with 2 nodes 19.3 database on linux 7.8 servers.
the issue is the following:
whenever the servers are rebooted (gracefully of abnormally) the cluster wont come up until issue the command "oracleasm scandisks " manually, only but then the cluster would be able to start again.
the same issue happened on another RAC system (installed recently) and the issue is reproducible on it.
i followed the documentation with no success
Oracle Linux 7: ASM Disks Created on FCOE Target Disks are Not Visible After System Reboot ( Doc ID 2065945.1 )
Oracleasm Is Not Showing ASM Disks After Reboot ( Doc ID 2043733.1 )
