Using ASM on any SOLARIS platform and not using a volume manager to manage the disks. Under this circumstances, the disks are identified under path /dev/rdsk.
The problem is the disks are not discovered when the instance is started.
Basic points that need to be reviewed:
* permissions of the device are set for the oracle owner, group and mode 0660.
* Parameter asm_diskstring is configured with a value that resolves the disks to be used.
Queries over v$asm_disk does not return rows or does not return all the expected disks.
