-Because the disk discovery order is not guaranteed, the kernel name of the disk can change across booting options for machines with multiple disks. For instance, `/dev/sda` becomes `/dev/sdb` and vice versa.
-To avoid this issue, you must use persistent disk attributes, such as the disk World Wide Name (WWN). To use the disk WWN, replace the `deviceName` parameter with the `wwnWithExtension` parameter. Depending on the parameter that you use, enter the disk name, for example, `/dev/sda` or the disk WWN, for example, `"0x64cd98f04fde100024684cf3034da5c2"`. Ensure that you enter the disk WWN value within quotes so that it is used as a string value and not a hexadecimal value.
+Because the disk discovery order is not guaranteed, the kernel name of the disk can change across booting options for machines with multiple disks. For example, `/dev/sda` becomes `/dev/sdb` and vice versa. To avoid this issue, you must use persistent disk attributes, such as the disk World Wide Name (WWN) or `/dev/disk/by-path/`. It is recommended to use the `/dev/disk/by-path/<device_path>` link to the storage location. To use the disk WWN, replace the `deviceName` parameter with the `wwnWithExtension` parameter. Depending on the parameter that you use, enter either of the following values:
+
+* The disk name. For example, `/dev/sda`, or `/dev/disk/by-path/`.
+* The disk WWN. For example, `"0x64cd98f04fde100024684cf3034da5c2"`. Ensure that you enter the disk WWN value within quotes so that it is used as a string value and not a hexadecimal value.
 
 Failure to meet these requirements for the `rootDeviceHints` parameter might result in the following error:
