Make sure you fulfill the prerequisites described in this section and
familiarize yourself with all the sections in the document before starting.
Continuing or Stopping Backups
Use the following guidelines if you are installing or replacing a drive in a
drive bay assembly (DBA) already in the library.
Ensuring ESD Protection
The repair environment for the library must be free of conditions that
could cause electrostatic discharge (ESD). To protect the library from ESD,
follow these procedures when repairing or testing the library:
 Place a static protection mat on the work surface used while removing
and installing library components. Use a 1-megohm resistor to ground
the static protection mat.
 Wear a static protection wrist band whenever you handle library
components that have been removed from their antistatic bags. Connect
this wrist band to the static protection mat or to other suitable ESD
grounding.
 Keep all electronic components in antistatic bags when not in use.
Robotic Control
Path Description
QIP or RIM
(all libraries) Backups running to all other drives in the library (or partition) can safely
continue while you install a new drive or replace an existing one.
Direct-attached
Fibre Channel drive
(Spectra T200,
T380, T680) Backups running to other drives in the library (or partition) can safely continue
while you install a new drive or replace an existing one, unless the drive you are
replacing is the one exporting the library (that is, providing the robotic control
path for the partition). If the drive you are replacing provides the control path
for the robotics, stop backup operations to the partition.
Note: T950 and T-Finity libraries do not support using a direct-attached drive
to provide the robotic control path.
Note: Selecting a drive to provide the robotic control path is part of configuring a partition. Refer to
the library’s User Guide for more information.
