NAME sam_undamage - Clears damaged and stale status of archive entries of a file or directory SYNOPSIS cc [ flag ... ] file ... -L/opt/SUNWsamfs/lib -lsam [library ... ] #include "/opt/SUNWsamfs/include/lib.h" int sam_undamage(const char *path, int num_opts, ... ); DESCRIPTION Using a Sun Storage Archive Manager system call, sam_undamage() lets you mark archive copies of a file or a directory as undamaged and not stale, based on the archive copy number and/or the media type and VSN specified. The function also marks the file itself as undamaged. path is the file on which to clear the attributes, followed by a sequence of num_opts input characters or options. Indivi- dual options are described below. There are several ways to mark one or more copies as undam- aged and unstale. These ways are as follows: o By copy number o By copy number, media type, and VSN o By copy number and media type o By media type o By media type and VSN OPTIONS a Rearchives the damaged copy. c copy_no Marks the specified archive copy number as undam- aged. If one or more 'c' options are specified, only those archive copies (1, 2, 3, or 4) are marked as undamaged. Specify 1, 2, 3, or 4 for copy_no. Either a "c copy_no" or a "m media" option must be specified. M Marks only metadata as undamaged. This includes directories, the segment index and removable-media files. Regular files are not marked as undamaged. If you are marking a directory as undamaged, you must specify the "M" option. m media_type Marks all copies from the specified media_type as undamaged. For the list of possible media_type specifications, see the mcf(4) man page. Either a "c copy_no" or a "m media" option must be speci- fied. If you specify a "m media" option, you can also specify a "v vsn" option. v vsn Marks the archive copies on vsn as undamaged. For vsn, specify a volume serial name (VSN). If you specify a "v vsn" option, you must also specify a "m media" option. RETURN VALUES Upon successful completion a value of 0 is returned. Other- wise, a value of -1 is returned and errno is set to indicate the error.
