Host Attachment

Hosts can be attached to the library in the following ways:

• Library Control Path on page 40

• Data Path on page 41

• Path Failover on page 42

• Network on page 43

Library Control Path The library control path is used to send SCSI commands to the library.

The Scalar i6000 offers several different control path options:

• HP and IBM LTO-5 or LTO-6 Native Fibre Channel (Ethernet

Expansion Blade included) — A tape drive hosts the library control

path and forwards media changer commands to the library

controller. Commands for both the tape drive and the library are

received by the drive. This shared SCSI protocol link uses the Fibre

Channel connection on the drive so a dedicated port for library

control is not needed. You must have at least one HP or IBM LTO-5

or LTO-6 FC drive installed in the library. The drive must be attached

to an Ethernet Expansion blade. For more information, see the

Scalar i6000 User’s Guide

Note: HP LTO-5 and LTO-6 drives support control path

connectivity in version i8 and higher.

Note: IBM LTO-5 and LTO-6 drives support control path

connectivity in version i12 and higher and only with Gen2

libraries (robot and electronics).

• Path Failover (previously Native Storage Networking (nSNW))

(Ethernet Expansion Blade Attached) — Path failover can be used

to provide redundant or multiple control paths.

A tape drive hosts the library control path and forwards media

changer commands to the library controller. Commands for both

the tape drive and the library are received by the drive. This shared
