Chapter 2 Description
Library Features
Scalar i6000 User’s Guide 12
The FC I/O blade manages data path conditioning along the path
between itself and the library drives. Data path monitoring automatically
occurs at regular, configurable intervals. The I/O blade generates a RAS
ticket if monitoring tests fail for two intervals. This indicates either loss of
connectivity or drive failure. The FC I/O blades include the data path
conditioning feature. Administrators can use the LMC to configure data
path conditioning.
Host Attachment 2
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 information, 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 management control blade (MCB)
has one library control port (FC or SCSI) connecting to the controlling
host computer.
• FC drives can be attached to FC I/O blades 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 2
The library can be managed locally or remotely using the LMC. Locally,
the LMC appears on the touch screen on the front of the library.
Remotely, the LMC is accessed through a client instance of the LMC
software on any computer on the network. For more information about
accessing

page 265. For more information about the LMC, see Library
Management Console (LMC) on page 271.
