asm_diskstring can be set in the ASM parameterfile and in the GPnP profile as well. Grid Infrastructure needs to know where to search for ASM disks before starting ASM and reading the ASM parameterfile, the GPnP profile makes that possible.
dsget Retrieves the discovery diskstring value that is used by the Oracle ASM Instance and its clients Synopsis dsget [ --normal | --profile [ -f ] | --parameter ] Description The options for the dsget command are described below. --normal - Retrieves the discovery string from the Grid Plug and Play (GPnP) profile and the one that is set in the Oracle ASM instance. It returns one row each for the profile and parameter setting. This is the default setting. --parameter - Retrieves the ASM_DISKSTRING parameter setting of the Oracle ASM instance. --profile - Retrieves the discovery string from the GPnP profile. -f - If -f is specified, retrieves the discovery string from the local GPnP profile. This parameter can only be specified if --profile is specified. Examples The following example uses dsget to retrieve the current discovery diskstring value from the GPnP profile and the ASM_DISKSTRING parameter.
