Installer does not list the initialized disks immediately after initializing the disks during I/O fencing configuration

When you choose to configure I/O fencing after the installer starts the processes, you should have at least three initialized shared disks. If you do not have three shared disks, the installer can initialize the shared disks. After the installer initializes the disks, the installer does not list the initialized disks immediately.

Workaround:

After you initialize the disks, if you do not see the new disks in the installer list, wait for several seconds. Then select y to continue to configure I/O fencing. The installer lists the initialized disks.
