The --list --target action lists the attributes of targets, including target name, size, host name, ASM disk group name, the list of IP addresses (a visible-to IP address list) indicating which database servers have access to the target, and the list of IP addresses (a discovered-by IP address list) indicating which database servers have logged into the target.
If an ASM disk group name is specified, the action lists all local targets created for the specified ASM disk group. Otherwise, the action lists all local targets created for quorum disks.
