By default, the ASM_DISKSTRING_UPDATE parameter is set to false in the sco.properties file. This parameter is set to false assuming that the value assigned to asm_diskstring includes the cloned disks path as well. However, sometimes the value assigned might not include the cloned disks path.
You must set the value of the ASM_DISKSTRING_UPDATE parameter to true to update the asm_diskstring database parameter to include the cloned disks path. After setting the ASM_DISKSTRING_UPDATE parameter to true, you must restart the SnapCenter Plug-in Loader (SPL) service.
