9.5 Mounting Volumes
In the following example, DKA500: is the ODS-5 disk, and DKA200: is
the ODS-2 disk.
$ BACKUP/LOG/CONVERT DKA500:[*...]*.*;* DKA200:[*...]*.*;*
%BACKUP-I-ODS5CONV, structure level 5 files will be converted to
structure level 2 on DKA200:
-BACKUP-I-ODS5LOSS, conversion may result in loss of structure level 5
file attributes
%BACKUP-S-CREDIR, created directory DKA200:[TEST_FILES.SUB$$DIR$]
%BACKUP-S-CREATED, created DKA200:[TEST_FILES.SUB$$DIR$]SUB$_$_FILE_$.DAT;1
%BACKUP-S-CREATED, created DKA200:[TEST_FILES]THIS$IS$A$TEST$_FILE_$.DAT;1
– Saving individual ODS-5 files in an ODS-2 save set
You can use this method to save ODS-5 files in a save set that can be read
on a system running a version of OpenVMS prior to Version 7.2.
In the following example, DKA500: is an ODS-5 disk, and DKA200: is an
ODS-2 disk; FILES.BCK is the ODS-2 save set.
$ BACKUP/LOG/CONVERT DKA500:[*...]*.*;* DKA200:FILES.BCK/SAVE
%BACKUP-I-ODS5CONV, structure level 5 files will be converted to
structure level 2 on DKA200:
-BACKUP-I-ODS5LOSS, conversion may result in loss of structure level 5
file attributes
%BACKUP-S-COPIED, copied DKA200:[000000]000000.DIR;1
%BACKUP-S-COPIED, copied DKA200:[000000]TEST_FILES.DIR;1
%BACKUP-S-COPIEDAS, copied DKA200:[TEST_FILES]Sub^_^{Dir^}.DIR;1 as
DKA200:[TEST_FILES]SUB$$DIR$.DIR;1
%BACKUP-S-COPIEDAS, copied
DKA200:[TEST_FILES.Sub^_^{Dir^}]Sub^&_~_File_~.Dat;1 as
DKA200:[TEST_FILES.SUB$$DIR$]SUB$_$_FILE_$.DAT;1
%BACKUP-S-COPIEDAS, copied
DKA200:[TEST_FILES]This^_is^_a^_Test^{_File_^}.Dat;1 as
DKA200:[TEST_FILES]THIS$IS$A$TEST$_FILE_$.DAT;1
If BACKUP cannot convert a file name within its existing directory, it converts
the file name and leaves it unconnected so that ANALYZE /DISK /REPAIR can
connect it to the [SYSLOST] directory, where the file has an ODS-2-compliant
name. BACKUP also displays messages similar to the following:
%BACKUP-I-RECOVCNT, 5 files could not be converted into a directory on DKA100:
-BACKUP-I-RECOVCMD, use the Analyze/Disk_Structure/Repair command to recover files
In this case, you need to move the file from [SYSLOST] to the appropriate
directory. Refer to the created as log messages to see where the file would
logically be placed and place it there manually.
9.5.6 Modifying Disk Volume Characteristics
Use the DCL command SET VOLUME to modify the characteristics of one or
more mounted Files–11 disk volumes. To use this command, you must have write
access to the index file on the volume. If you are not the owner of the volume,
you must have either a system UIC or the user privilege SYSPRV. You must then
specify the name of one or more mounted Files–11 volumes.
The following examples illustrate how you can use the SET VOLUME command.
