Property	Description
Parameter type	String
Syntax	ASM_DISKSTRING = discovery_string [, discovery_string ] ...
Default value	The null string; Oracle Automatic Storage Management discovery finds all disks in an operating system-specific location to which the Oracle Automatic Storage Management instance has read/write access.
Modifiable	ALTER SESSION, ALTER SYSTEM
Modifiable in a PDB	Yes
Oracle RAC	Multiple instances can have different values. Different nodes might see the same disks under different names; however, each instance must be able to use its ASM_DISKSTRING to discover the same physical media as the other nodes in the cluster.
