im in the process of installing oracle grid infrastructure 19c on linux 2 nodes,

i have 3 disks that to be used for OCR

/dev/sdd --10GB

/dev/sde -- 10Gb

/dev/sdf -- 10Gb

/dev/sdg --100gb -- DATA

/dev/sdu --100Gb --DATA

/dev/sdv --200gb --FRA

/dev/sdt--20GB --FRA

before starting the installation i need to use oracleasm create disk ocr

1- how can i specify the 3 disks to be used for OCR group

2- is it possible to create it with only 1 disk and after installation use asmca to add the rest of disks to OCR group

Howdy, Stranger!
