Host Attachment
Requests issued from the host application result in cartridge movement
in the library. The primary requests issued are for mounting and
dismounting cartridges in and out of the tape drives and for importing
and exporting cartridges in and out of the library. The library manages
the physical location. In addition to requesting cartridge movement in the
library, the host application can use the FC or SCSI command interface to
obtain status, configuration information, and cartridge storage
information from the library.
Hosts can be attached to the library in the following ways:
• SDLT-320 SCSI-interfaced drives can be connected to the SAN when
they are directly connected to an external Storage Networking
Controller (SNC) 5100. There is no area provided to mount the SNC
inside the library modules, so you must plan for extra rack space near
the library.
• FC and SCSI drives can be directly-attached to host systems or to the
SAN. In these configurations, the MCB has one library control port
(Fibre Channel or SCSI) connecting to the controlling host computer.
• Attachment of the FC drives to the FC I/O blade in the I/O
management unit. There are two ports on each FC I/O blade that can
be connected directly to the host or to the SAN.
Remote Management
The library can be managed locally or remotely using the LMC. Locally,
the LMC is displayed on the touch screen on the front of the library.
Remotely, the LMC is accessed through a client instance of the ADIC
Management Console (AMC) software on any computer on the network.
You also can access the LMC using a Java-enabled browser.
