Use the VMBTCPY utility to make complete copies of CA VM:Backup tapes to send to CA for diagnostic purposes. CA may request a copy of a production tape when troubleshooting a problem.
VMBTCPY copies and preserves the following input tapes:
If VMBTCPY encounters a null data set created by the CA VM:Archiver Merge/Purge utility, VMBTCPY tolerates the null data set and preserves it in the copy.
The VMBTCPY-created copy has the same volser number as the original tape. VMBTCPY copies one physical tape to one physical tape, regardless of what other tapes may be chained to the tape being copied.
Common CMS routines, such as MOVEFILE, can copy CA VM:Backup tapes. However, the resulting copies may be incomplete because CA VM:Backup writes data at record lengths up to 64K and CMS routines only support tape structures with record lengths up to 32K. Using VMBTCPY ensures the integrity of CA VM:Backup tape copies.
This utility has the following format:
VMBTCPY {"Parms"}
Parms:
?
| svaddr [(DUPSCAN]
| svaddr tvaddr [("Options")]
Options:
[DISK]
[DUPFIX]
[TEST]
[NOVal]
[FIX]
Displays help information.
Identifies the virtual address of the source tape drive. This must be different from the virtual address of the target tape drive (tvaddr).
Identifies the virtual address of the target tape drive. This must be different from the virtual address of the source tape drive (svaddr).
Writes output messages to VMBTCPY REPORT, a CMS file on the requesting user's A-disk. If you select the DISK option, output messages also go to the terminal. If the output file VMBTCPY REPORT already exists when you specify the DISK option, the original file will be erased and a new output file will be created. Output messages always go to the terminal regardless of whether the DISK option is selected. User responses to VMBTCPY requests are not included in the VMBTCPY REPORT file.
Specifies that duplicate records that are found on the input tape during the copy process are to be deleted.
Specifies that the input tape is to be scanned for duplicate or missing records and report on any duplicate or missing records. The tape is not copied.
Verifies that:
VMBTCPY does not actually copy any tapes with the TEST option. Because no copying is performed when the TEST option is specified, source tape format problems cannot be detected.
Prevents VMBTCPY from ending prematurely if the source tape contains either an invalid CA VM:Backup header label or an invalid tape format. VMBTCPY will issue error messages, but copying continues. Use this option only when copying a CA VM:Backup tape that you know has either an invalid header label or an invalid tape format.
Specifies that if there are two VOL1 labels written on a source tape, VMBTCPY will only write one VOL1 label (the second one) to the target tape.
