Table 51 Parameters for the DFSMSdss Command (Version 2/Volume Copying) (continued)
Description Value Parameter
to the backup tape or disk. In this case, it is not necessary to specify
COPYVOLID to copy the volume label.
DUMPCONDITIONING is used when you want to specify that the purpose
of the copy operation is to create a backup copy and not for using the
copied volume for application. N/A DUMPCONDITIONING
1
This command sets the copy operation mode to NOCOPY mode. When
this command is specified, the background copying process is omitted
from the copy operation. N/A FCNOCOPY
The relationship made by NOCOPY mode is copied in the background.
When all the data is copied, the relationship is released automatically. N/A FCNOCOPYTOCOPY
Executes the Version 2 copy operation as a priority. If Version 2 cannot
be used, executes the Concurrent Copy or copy operation via the host. PREFERRED FASTREPLICATION
When FASTREPLICATION is not specified, the copy operation will be
performed in the same way as when PREFERRED is specified.
Executes the Version 2 copy operation unconditionally. If Version 2 cannot
be used, reports an error. REQUIRED
Does not execute the Version 2 copy operation. NONE
This option is for temporarily suspending the write operation from the
host to the S-VOLs when you establish relationships to maintain the N/A FCCGFREEZE
consistency of data. To resume the write operation from the host to the
S-VOLs, use the DFSMSdss CGCREATE command or the TSO FCWITHDR
command.
To use the Incremental FlashCopy function, use FCINCREMENTAL. For
details about the Incremental FlashCopy function, see the
(page 38) .
N/A FCINCREMENTAL
When FCINCREMENTAL is specified, a relationship covering the entire
volume is created. This relationship is maintained after the background
copying process is completed. When FCINCREMENTAL is specified, the
following additional functionality becomes available:
•
You can manage the differential data between the S-VOL and the
T-VOL.
• When you re-execute the COPY command, only the differential data
will be copied to the T-VOL.
If you reverse the S-VOL and the T-VOL and execute the COPY command
(Reverse Restore), only the differential data will be copied to the resulting
T-VOL.
2
Use FCINCREMENTALLAST to delete the relationship after completing
the copy operation of the differential data. N/A FCINCREMENTALLAST
When you re-execute the COPY command by specifying
FCINCREMENTALLAST on a relationship created by specifying
FCINCREMENTAL, only the differential data will be copied to the T-VOL
and after the copy has completed, the relationship is be deleted.
If you reverse the S-VOL and the T-VOL and execute the COPY command
(Reverse Restore), only the differential data will be copied to the resulting
T-VOL. After Reverse Restore has completed, the relationship will be
deleted.
Use FCINCRVERIFY to verify the condition established when re-executing
the COPY command by specifying FCINCREMENTAL on the relationship
created by using FCINCREMENTAL. N/A FCINCRVERIFY
The copy operation will be executed only when you specify the S-VOL
and the T-VOL in the same way as when the relationship was created. NOREVERSE
