Adding disk to VOTING diskgroup

Dear Experts,

We are upgrading 2 node RAC 12.1.0.2(version) to 19c. We are running ./gridSetup.sh -dryRunForUpgrade and it warns about diskgroup OCRVOTE1 space.

[INS-43100] Installer has detected that the free space available in the ASM diskgroup OCRVOTE1 is 2 GB, and it is insufficient to proceed with the upgrade. To upgrade Oracle Grid Infrastructure you should have at least 20.9 GB free space in this diskgroup.

Storage team have provisioned multiple disks during implementation. We have provided output below. What should be the action plan to be followed. Please guide.
