Whether the P-VOL can be written to when the pair is split due to error.
- Data: The P-VOL cannot be written to.
- Status: The P-VOL can be written to only if the primary system can change the S-VOL status to PSUE (TrueCopy) or Suspend (TrueCopy for Mainframe). If the primary system cannot change the S-VOL status, the P-VOL cannot be written to.

CFW Data
(VSP 5000 series)
|
TCz only.
Whether CFW (DASD fast write) data is copied to the S-VOL.
- Primary Volume Only: Data not copied (default).
- Secondary Volume Copy: Data is copied.
The value set for the selected pair is the default.
Note:
- To apply the pair option that is set on the P-VOL to the S-VOL, split and then resynchronize the
TCz pair.
- Do not specify
Primary Volume Only if system option mode (SOM) 1091 is ON. If you do, I/O to the S-VOL might terminate abnormally.
- Do not set SOM 1091 to ON if you changed the CFW data setting after you created the
TCz pair. If you do, I/O to the S-VOL might terminate abnormally.
