IBM SG24-5360-00 manual Using SnapShot to Copy a File from One Volume to Another

Page 57

Notes: In Figure 25, in the DEVICE DETAIL REPORT, the data stored for device 80F reflects snapping the data from 80E. Also, the physical used capacity reflects its source on device 80E. The key indicator is the

NET-CAPACITY-LOAD (%), which shows that the PROD capacity of the RVA has remained constant at 51.01%.

Using the VOLUME command, we verified that the target volume serial number had been changed to PATEV3.

The actual time to accomplish the copy was less than 1 sec, as indicated by messages IXFP22I and IXFP20I, which show the start and end times for the copy.

We used the above configuration as the base for all other manipulations of the RVA during the creation of this redbook. The RVA now contains two volumes, which have the same content but different volume serial numbers.

B.1.3 Using SnapShot to Copy a File from One Volume to Another

In the Figure 26, we show the snapping of a single file from one volume to another. The example shows the copy being done twiceÐonce without the NOPROMPT option, and once with it. When NOPROMPT is selected, message IXFP23D is suppressed.

B.1.4 Using SnapShot to Copy Files with Relocation

In the Figure 27 on page 48, we show two attempts to copy a file from device 80E to 80F with relocation of the data on the target volume. The first copy is successful. The second copy fails because there is already a file on the target with the same file ID in the VTOC and it is unexpired. (The first would have failed also except that the first file′s expiration date had been reached.)
