Table 3-3 provides an overview of each configuration option. Read through
the table to determine which options you need to set, then follow the steps on
the referenced pages.

Description See...
SCSI Configuration (221L)
SCSI IDs Setting SCSI IDs is required for 221L library operation. View the
default settings and change them if necessary.
“Setting SCSI
Configuration
Options (221L)”
on page 32
SCSI Parity By default, parity checking is enabled. If desired, you can disable
parity checking for the library if the SCSI adapter card connected to
the library does not support parity checking.
Fibre Channel Configuration (221L-FC)
Hard Loop IDs You can request specific Loop IDs to be used by the library and tape
drive(s) during Fibre Channel initialization.
“Setting Fibre
Channel
Configuration
Options
(221L-FC)” on
page 34
Require Hard
ID
You can specify whether the library always attempts to obtain the
specified Hard Loop ID (hard addressing) or accepts an ID assigned
by the loop if the Hard Loop ID is unavailable (soft addressing).
Override Drive
WWN
You can specify whether the tape drives use the world-wide names
(WWNs) set by their manufacturer or WWNs generated by the
library. Overriding the tape drives’ WWNs allows you to replace a
tape drive without causing it to report a new WWN to an
application.
Ethernet Configuration
Ethernet
Addresses
If you are using the library’s Ethernet interface, you can set the
library’s IP address, SNMP recipient address, subnet mask, and
gateway address for communication across your Ethernet network.
You can also choose whether the library uses a fixed IP address
(static addressing) or an address assigned by a DHCP server.

Configuration
Options” on
page 38
Ethernet
Security
If you need to identify the library’s SNMP settings to a
network-based monitoring application, you can view the library’s
Read, Write, and Broadcast community access strings. If desired,
you can change these settings from their default values.
You can also view and set the library’s FTP user name and password
used for transferring firmware files and creating diagnostic listings.
Emulation
Emulation
Mode
Setting an emulation mode is required if your application software
does not support a 221L, but does support an Exabyte 210, 430, or
480 library.

Emulation Mode”
