You can use a Compatible FlashCopy® T-VOL as a URz P-VOL regardless of the status of the URz pair. Note the following:
- If a Compatible FlashCopy® volume and a URz volume cannot be shared, the host might receive a report that a Compatible FlashCopy® T-VOL is a PPRC P-VOL.
- If the S-VOL and T-VOL of a Compatible FlashCopy® relationship are Dynamic Provisioning for Mainframe volumes, the number of pages remaining in the T-VOL might differ, depending on the timing.
- If a Compatible FlashCopy® relationship is suspended during a copy operation, the shared URz pair is also suspended. Since data is copied asynchronously in URz, there will be a noticeable delay between the time the Compatible FlashCopy® is suspended and when the URz pair is suspended.
- A URz P-VOL combined with the multiple primary system and the secondary system using CCI, and the Compatible FlashCopy® T-VOL cannot be shared.
- The URz P-VOL in 3DC multi-target configuration using 3 URz sites and a Compatible FlashCopy® target volume cannot be shared.
- The volume copy operation (of which a T-VOL is a URz P-VOL) might not be performed by using some applications on the host. For details, see Why you use IBM Db2® Cloning Tool for z/OS®.
