External Interfaces
A-22 Fifth Edition 95897
HBA Requirements
CAUTION:
Mismatching SCSI operation types: The host bus adapters (HBAs) in the
customer’s server must match the library’s SCSI bus type. If the
interface to the library is HVD, then the customer’s server must contain
an HVD-compatible HBA. Likewise, if the interface to the library is LVD,
then the server must contain an LVD-compatible HBA.
The server that the SCSI bus attaches to must have a compatible HBA. If the
interface to the library is HVD, the customer’s server must contain an HVD-
compatible HBA. Likewise, if the interface to the library is LVD, then the server
must contain an LVD-compatible HBA.
The following table compares device requirements—library, drives, and
server—for LVD and HVD operation:
L-Series Library Admin
The L-Series Library Admin is an optional web-based interface to the library.
This interface lets a library’s users configure, operate, and monitor the library
through a workstation or PC that is running a Netscape or Microsoft browser.
This interface must first be enabled and configured on the library. Installation
and configuration instructions appear in the documentation that ships with the
software components.
