Requires OPER privilege.
PHY_IO (physical I/O) privilege is required when specifying the Alpha-only qualifiers that change the characteristics of shadow sets. These qualifiers also can be specified using the SET SHADOW command, which provides additional options for controlling shadow sets. Qualifier settings for shadow sets remain in effect until they are changed using either SET DEVICE or SET SHADOW or until the shadow set or shadow set member is dismounted. If the shadow set is remounted or a shadow set member is returned to the shadow set from which it was dismounted, the settings must be specified again.
