NAME

sam_restore_file - Creates an offline StorageTek QFS file.

SYNOPSIS

cc [ flag … ] file … -L∕opt∕SUNWsamfs∕lib -lsam [ library … ]

#include "∕opt∕SUNWsamfs∕include∕stat.h"

int sam_restore_file(const char * path , struct sam_stat * buf , size_t bufsize );

DESCRIPTION

sam_restore_file() creates an offline file in a StorageTek QFS or Oracle HSM file system. sam_restore_file() creates an offline file using information supplied by the user and obtained from a source such as the archiver.log file. The file must not exist.

Note that the program calling this function is responsible for creating all directories in the path before calling the function.

path is the pathname to the file to be created. It may be an absolute or relative pathname but must be no longer than PATH_MAX (see the ∕usr∕include∕limits.h file).

buf is a sam_stat (3x) structure (see sam_stat (3x)).

bufsize is the size of the sam_stat (3x) structure (see sam_stat (3x)).

The following members in the sam_stat (3x) structure must exist. All other fields are ignored.

Table 1: Required sam_stat Fields
NameTypeDescription
st_modeulong_tFile mode (see mknod (2))
st_uidulong_tUser ID of the file's owner
st_gidulong_tGroup ID of the file's owner
st_sizeu_longlong_tFile size in bytes
st_atimeulong_tTime of last access
st_ctimeulong_tTime of last file status change
st_mtimeulong_tTime of last data modification

The following members in the sam_copy_s structure must exist for all copies, if any. All other fields are ignored.

Table 2: Required sam_copy_s Fields
NameTypeDescription
media[4];charTwo character media type.
position;u_longlong_tPosition of the file on the media.
offset;uint_tLoc of copy in archive file in 512 bytes
creation_time;time_tTime the archive copy was created
vsn[32];charVolume serial name of the media
position

The position of the file recorded on the media.

offset

The location of this copy in the archive file in 512 bytes.

creation_time

This is the time that the archive was made. If creation_time is zero, it will be set to the value of time().

vsn

The volume serial name of the cartridge where the file resides.

media

The two character media type. See mcf (4). For example, the media type for DLT tape is lt.

RETURN VALUES

Upon succesful creation of a file a value of 0 is returned. Otherwise, a negative value is returned and errno is set to indicate the error. The possible return values are: dl dt-1∕dt dd p user is not root ∕p ∕dd dt-2∕dt dd p invalid media type ∕p ∕dd dt-3∕dt dd p invalid VSN ∕p ∕dd dt-5∕dt dd p file does not exist ∕p ∕dd dt-6∕dt dd p restore failed for some other reason ∕p ∕dd ∕dl
