Responding to Loss of Files on NonStop SMF Disk
Volumes
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 option in the RECOVER
FILES command, you can identify the physical target disk volume where you wish TMF
to place the logical recovered files. Furthermore, with the WHEREPHYSVOLIS option,
you can recover all the logical files on a specified physical volume. The TOPHYSVOL
and WHEREPHYSVOLIS options are mutually exclusive: if you specify both of these
options, WHEREPHYSVOLIS takes precedence and TOPHYSVOL is ignored.
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 RECOVERVDPPHASE1 option,
to recover the files.
This RECOVER FILES command illustrates how to recover files to a volume other than
the current physical location of the files:
TMF 38> RECOVER FILES $L1.*.*, TOPHYSVOL $D1, FROMARCHIVE
.
.
.
Note. 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).
Caution. The TOPHYSVOL, WHEREPHYSVOLIS, and RECOVERVDPPHASE1 options are
intended for use with NonStop Storage Management Foundation (SMF) files only. Before you
issue a RECOVER FILES command with any of these options, it is vital that you read “Options
for the SMF Product” in the RECOVER FILES command description in the TMF Reference
Manual.
