Prepare for Maintenance

PREPARE FOR MAINTENANCE

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.
Method	Description
QIP-attach drives	Backups running to all other drives in the library (or partition) can safely
(all libraries)	continue while you install a new drive or replace an existing one.
Direct-attach SCSI	If multiple direct‐attach SCSI drives are daisy‐chained on the same SCSI bus,
drives	adding or removing a drive interrupts communications on the bus. Stop backup
(Spectra T200,	operations to all of the drives in the daisy chain. Spectra Logic recommends
T380, T680)	shutting down and powering off the host computer before replacing a drive.
	Note: Both the T950 and the T‐Finity require a QIP for direct‐attach drive
	configurations.
Direct-attach Fibre	Backups running to other drives in the library (or partition) can safely continue
Channel drives	while you install a new drive or replace an existing one, unless the drive you are
(Spectra T200,	replacing is the one exporting the library (that is, providing the robotic control
T380, T680)	path for the partition). If the drive you are replacing provides the control path
	for the robotics, stop backup operations to the partition.
	Note: Both the T950 and the T‐Finity require a QIP for direct‐attach drive
	configurations.

Note: Selecting a drive to provide the robotic control path is part of configuring a partition. Refer to the individual User Guide for more information.

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:

ƒPlace a static protection mat on the work surface used while removing and installing library components. Use a 1‐megaohm resistor to ground the static protection mat.

ƒWear 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.

ƒKeep all components in antistatic bags when not in use.
