Abstract: A storage system includes a first storage apparatus including a first logical volume and a second storage apparatus including a second logical volume. The first and second logical volumes are set as a High Availability pair and associated with a virtual volume. When receiving a write request to the virtual volume, the storage system manages storage area in the first logical volume regarding to the write request as storage area during data duplication, writes data in duplicate, in order from the first logical volume to the second logical volume. When receiving a read request to the virtual volume, the first storage apparatus waits for completion of the data duplication and reads data from the first logical volume if the storage area is during the data duplication, and the first storage apparatus reads data from the first logical volume if the storage area is not during the data duplication.

Abstract: An exhaust purification system for a working machine reliably issues filter regeneration warnings to the operator, prompting manual regeneration, so that damage to the DPF device can be avoided. When a PM estimate becomes higher than a given value, a screen displays a warning message prompting manual regeneration. If the warning message fails to prompt the operator to perform manual regeneration and reference time t1 has passed since the display of the warning message, a speaker outputs a first warning sound. When the operator notices the first warning sound and turns on a regeneration switch, regeneration control is started. If the operator fails to notice the first warning sound and reference time t2 passes, the speaker instead outputs a second warning sound louder than the first warning sound. When the operator notices the second warning sound and turns on the regeneration switch, regeneration control is started.
