5.3 The smc_tar Utility
If you cannot use ftp to load content, as explained in Section 2.4 “Content Loading”
on page 2-5, you can use smc_tar. The smc_tar command extracts a content package
from a tar archival device or tar file. smc_tar parses the TOC file in the content
package and stores the data and index files associated with the title, as well as the
TOC file itself, into the correct locations on the Sun MediaCenter server.
smc_tar also works in the reverse direction, copying titles from a Sun MediaCenter
server to a tar device or file.
smc_tar works with one or more local or remote Sun MediaCenter servers. For
example, in a single command, you can copy titles from multiple local and remote
Sun MediaCenter servers to a local tape drive, for backup purposes. Detailed
examples are provided later.
You can run smc_tar on any SPARC/Solaris machine. To run smc_tar remotely,
you need only the smc_tar binary, which you can copy from /opt/SUNWsms/bin
on a Sun MediaCenter server with the current release of software.
5.3.1 Syntax and Options
The syntax for smc_tar is:
Options are analogues of tar options and are described as follows:
c
Specifies creation of a tar file or copying a title from the Sun MediaCenter server
to a tar device. Requires a source file argument of <server>:<title>.
x
Specifies extraction of a tar archival or file. Used for copying content packages
onto the Sun MediaCenter server.
b <blknum>
Specifies the blocking factor that was used to create the tar device contents.
<blknum> must be a multiple of 20; one block equals 512 bytes. The recommended
<blknum> value is 500 (256000 bytes). Most operating systems, including Solaris,
have a default block number value of 20. The location of <blknum> in the
smc_tar command line depends on the order of the b and f options. <blknum> is
smc_tar t|c|x[v][b][w] f <tar device> [<blksize>] [<server>:<title>]
