copying Dataset 2 only. If the EXTENTS parameter is not specified, the entire source volume is copied to
the T-VOL.
Figure 39 Copying Specified Dataset by Specifying EXTENTS Parameter Using TSO (FCESTABL) Command
To copy one or more dataset using the TSO (FCESTABL) command:
1. Check the VTOC list to confirm VTOC (including INDEX VTOC) and the address (cylinder number and
header number) of the dataset(s) that you want to copy.
2. Vary the T-VOL offline.
3. Execute the FCESTABL command. You must specify the following items by the EXTENTS parameter. If
you access a dataset that is not specified by the EXTENTS parameter, the operation cannot be
guaranteed.
• Dataset(s) to be copied. If you want to copy multiple datasets, you must specify the extents of all of
the desired datasets.
• VTOC address (Cylinder 0, header 0).
•VTOC.
If the dataset(s) uses the following items, you must also specify those items by the EXTENTS parameter.
•INDEX VTOC.
• VSAM volume dataset of the VSAM file (SYS1.VVDS.Vxxxxxx,xxxxxx is VOLSER).
4. Change the VOLSER of the T-VOL. You must change the VOLSER of the T-VOL before varying the T-VOL
online because the VOLSERs of the S-VOL and T-VOL become identical as a result of copying VTOC.
5. Vary the T-VOL online.
Adding ShadowImage - FlashCopy Pairs: FCESTABL
The following shows an example of the FCESTABL command.
Example: FCESTABL Command
Deleting ShadowImage - FlashCopy Pairs: FCWITHDR
The FCESTABL command can be issued to an ShadowImage - FlashCopy pair for which a relationship has
already been established. The following shows an example of the FCWITHDR command.
CAUTION: If a pair is deleted by the FCWITHDR command, the data integrity of the T-VOL cannot be
guaranteed.
Example: FCWITHDR Command
FCESTABL SDEVN(X’DE80’) TDEVN(X’DE81’) MODE(COPY) ONLINTGT(YES)
EXTENTS(X’00010000’ X’0100000E’)
