RECOVER FILES
Options for the SMF Product
The TOPHYSVOL and WHEREPHYSVOLIS parameters allow you to refer to physical
disk volumes managed by the NonStop Storage Management Foundation (SMF)
product. The SMF software enhances the automatic management of system storage.
A file stored on an SMF virtual disk is identified by a logical file name. A file that is not
associated with an SMF virtual disk process, however, is identified by a direct file
name. A file has either a logical or a direct file name, but it never has both. Logical
and direct file names are simply the external file names that applications use to identify
files either managed by the SMF product or not managed by it, respectively. The DP2
disk process, however, does not use external file names; instead, that process
identifies a file by a physical file name, which is simply an internal file name that maps
to the file’s logical or direct file name. As an example, for a file stored on an SMF
virtual disk, the logical file name might be \$SYS.$L1.SOME.DATA and the physical file
name might be $PHYS27.ZYS00000.A0000K29. For a file that is not managed by the
SMF software, the direct file name and physical file name are both the same (for
instance, \SYS.$P1.MORE.DATA).
For systems using the SMF product, the TMF catalog contains the logical file names of
files managed by SMF and the direct file names of files not managed by SMF. Thus,
when taking dumps of these files, or referring to them in the RECOVER FILES
command, you must refer to these files by their logical or direct file names, not by their
physical file names. Nevertheless, with the TOPHYSVOL parameter, you can identify
the physical target disk volume where you wish TMF to place the logical recovered
files. Furthermore, with the WHEREPHYSVOLIS parameter, you can recover all the
logical files on a specified physical volume.
It is important to remain aware of the free space available on the destination physical
volume; if the physical volume becomes full, the file recovery process aborts.
If a physical disk that contained a virtual disk process (VDP) catalog fails, you must
recover the files in two steps:
1. Issue a RECOVER FILES command with the RECOVERVDPPHASE1 option to
recover the VDP catalog.
2. Issue a RECOVER FILES command, without the RECOVERVDPPHPASE1 option,
to recover the files.

User’s Guide.
Output Displayed
As file recovery progresses, TMFCOM displays EMS messages about various events
that take place. The format and content of these messages varies. Examples appear
along with the command-entry examples.
Caution. The TOPHYSVOL option does not work when direct file names appear in file-set (in
other words, with files not managed by the SMF product).
