Before using FlashCopy® SE , you must install FlashCopy® SE and Dynamic Provisioning for Mainframe in the storage system.
You establish FlashCopy® SE volume relationships by issuing commands from any of the following mainframe host interfaces:
- PPRC TSO
- DFSMSdss
- ICKDSF
- ANTRQST macro
- z/VM CP
The following table describes the functionality supported by FlashCopy® SE.
|
Action |
Functionality |
Description |
|---|---|---|
|
Establishing relationships |
Volume copy |
Copies S-VOL updates to the T-VOL. This function does not perform a background copy. If a relationship established in NOCOPY mode is deleted, the data on the copy target can be inconsistent. |
|
Multiple relationships |
Supports up to 16 copy targets. |
|
|
Using consistency groups for dataset copies |
Creates snapshot data consistent across multiple volumes. |
|
|
Fast Reverse Restore |
Creates a relationship and reverses the S-VOL and T-VOL. |
|
|
Releasing relationships |
Deletes the relationship between the specified S-VOL and T-VOL. Because FlashCopy® SE operates only in NOCOPY mode, the relationship is deleted immediately after you execute the withdraw command. When you execute the withdraw command, you can specify whether or not to release already allocated areas. |
|
|
Displaying relationship status |
You can view relationship status using a host command. |
