NAME
libsji
- Standard Jukebox Interface (SJI) Library
DESCRIPTION
The Standard Jukebox Interface (SJI) is a public set of
interfaces that NetWorker uses to communicate with jukeboxes.
Generally the function of this library is to convert SJI
commands, as formed by NetWorker, to the appropriate SCSI
commands (since most autochangers are SCSI based). But the
underlying attachment to the jukebox is irrelevant to
the functioning of this interface.
There are three entry points into this library:
- void * sji_open ( char * devname )
-
This opens a channel to an SJI compliant jukebox, named
devname.
A channel token, of type
void *
is returned if the channel is opened successfully, otherwise a channel token
of type
NULL is returned.
The device name
devame
can be a specific ordinal
SCSI address, for example,
[email protected],
where
b
is the logical scsi bus,
t
is the SCSI target, and
l
is the SCSI logical unit number (LUN) on that target.
For platforms that do not use EMC device drivers, the device name can also
be a platform-specific
style device name, for example,
/dev/sjid1u1.
- int sji_cmd ( void *token, int cmd, void *arg )
-
This sends an SJI command to the device opened by
the
sji_open
command.
- void sji_close ( void *token )
-
This closes a channel to the device opened by the call made to the
sji_open
command.
FILES
The location of the SJI library varies from platform to platform.
