Tape to Tape copy of vxdump filesets

Hi,

HP-UX 11i V3 on itanium.

I need to make another copy of an Ultrium tape that has multiple vxdump filesets on it, I have found the below, but this seems to indicate copying the files to disk first and then back to a new tape. It also doesn't specify whether this prcedure can handle multiple vxdump filesets on the tape.

==========================================
Duplicating dump(1)/vxdump(1) tapes

Copy contents of dump(1)/vxdump(1) tape to disk:
# dd if=/dev/rmt/ if=/tmp/dump.contents bs=32k

Copy disk file to new tape:
# dd if=/tmp/dump.contents of=/dev/rmt/ bs=32k

Verify new tape is readable by restore(1)/vxrestore(1):
# restore tf /dev/rmt/, or
# vxrestore tf /dev/rmt/
==============================================

Is there a way of a direct tape to tape copy?

any advise appreciated.
Thanks

Shalom,

If the system has access to two tape devices, yes.

dd if=/dev/rmt/ of=/dev/rmt2/ bs=32k

Both tape devices must be local and it would be helpful if they were the same type.
