RESTORE
FILES= maxfiles If you are restoring a large number of files from an MPE V/E (transport)
tape, specify a number at least as large as the number of files to be
restored. The default is 4000.
This parameter is ignored when you are restoring MPE XL format store
tapes. No limit is imposed.
When a FILES= option is put in an indirect file, it is ignored.
DEV= device Specifies the device on which the restored files are to reside. It takes one of
two forms:
devclass Specifies the type of device. The file is allocated to the
home volume set (within the specified device class) of the
group into which it is being restored.
ldn Specifies a particular logical device number (ldn)
corresponding to a particular device. The file will be
allocated to that device only if one of the volumes in the
home volume set (of the group into which a file is being
restored) currently occupies the device.
By default, MPE/iX attempts to restore the file on a logical device
compatible with the type and subtype specified in the file's file label and
with the type and subtype of the mounted home volume set (of the group
into which a file is being restored). If this fails, an attempt is made to
restore the file on the same device class as specified in the file's file label
and that of the mounted home volume set (of the group into which a file is
being restored). If this fails, an attempt is made to restore the file on any
member of the home volume set (of the group into which a file is being
restored). If this fails, the file is not restored.
You cannot use DEV with the VOLSET, VOLCLASS, or VOL options.
VOL The volume on which the restored files are to reside. If there is no room on
this volume, the device restrictions will default to the volume's class; if
this fails, it will default to the volume's set; if both fail, the files will not be
restored.
volumename A volume name. If no VOLCLASS or VOLSET options are specified,
volumename must reside on the system volume set.
VOLCLASS The volume class on which the files are to reside. If there is no room on this
volume class, the device restrictions will default to the volume class's
volume set; if this fails, the files will not be restored.
volumeclassname A volume class name. If no VOLSET options are specified, volumeclassname
must reside on the system volume set.
VOLSET Specifies the volume set on which the files are to reside. If the specified
directories do not exist on that volume set, the file(s) will be restored to the
specified group and account.
