Verification of an error occurrence

Reading DP-VOL data from the host

(Read the entire volumes specified in the following table from the host.)

• If no errors occur, the read succeeds.
• If an error occurs, SIM code 680001 is output. The read cannot be performed with the check response returned to the host.

Creating an SI pair

(Create an SI pair that uses a volume specified in the following table as the DP-VOL.)

• To perform the verification while continuing your operations, you must control the number of volumes to be read at a time and the read performances in order to reduce the processor utilization rate.
• The free pool capacity for the copy destination volume is required.

• If no errors occur, the pair creation succeeds.
• If an error occurs, SIM code 680001 is output. The pair cannot be created, and the pair is suspended by error.

Health check feature*

(On the volumes automatically identified as specified in the following table, whether an error occurs is verified.)

• The host operation is not required.
• The health check feature enables the verification while continuing your operations, because the processor utilization rate is controlled to about 15%.

• If no errors occur, health check is complete without SIM code 680001 output.
• If an error occurs, health check is complete with SIM code 680001 output.
