Electrical Safety
The static discharged by human bodies can damage static-sensitive components on the boards.
When installing and maintaining the equipment, observe appropriate electrostatic safety precautions
to prevent personnel injuries or device damage.
When operating a device in an electrostatic sensitive area, you must take electrostatic-discharge
(ESD)-preventive measures. These include wearing ESD-preventive gloves, an ESD-preventive wrist
strap, and ESD-preventive clothes to avoid personnel injury or device damage.
To prevent damage to the device, pay attention to the following during operations:
•
Do not touch devices with bare hands because ESD from the human body may damage the
electrostatically sensitive elements on a board.
•
When dealing with the server or any of the internal components, wear an ESD-preventive wrist
strap, ESD-preventive gloves, and ESD-preventive suit.
High availability (HA) appliance service considerations
Attention: A HA or multi-node appliance is serviced in the same manner as a single node appliance.

About the disk drive carrier
This section describes how to remove and replace a hot-swappable storage disk drive together with
its carrier in a Veritas 5U84 Storage Shelf.
The 5U84 Primary Storage Shelf and the 5U84 Expansion Storage Shelf each use a 5U chassis.
Each chassis contains two sliding drawers that are accessible from the front of the storage shelves.
Each drawer can hold 42 Disk Drive In Carrier (DDIC) modules. The DDIC modules are installed in
each of the drive drawer slots, which can hold a total of 84 disk drives. Each DDIC module holds one
3.5" SAS-3, 7200 rpm hard disk drive, in either 4-TB or 8-TB capacities (5340/5350 Appliance), or
10-TB capacities (3340 Appliance).
Caution: You must complete a drive swap within two minutes. Leaving the drive slot open for longer
than two minutes can result in the appliance overheating and cause other components to fail.
Caution: Swap one drive at a time only. Removing more than one drive at one time can affect system
functionality.
Caution: Verify that the capacity of the drive is the same as the capacity of the drive that is being
replaced. Veritas does not support populating the 5340/5350 storage shelf's individual disk drive
drawers with both 4-TB and 8-TB disk drives.
Requirements
Verify you have the following items:
•
4-TB/8-TB/10-TB hot-swappable disk drive with its carrier
•
Screwdriver with a Torx T20 bit
•
ESD wrist strap
Locating the appliance with the faulty component
Use the following steps to locate the appliance with the faulty component.
To locate the appliance with the faulty component
1
Contact the Veritas Field Service Coordinators to let them know that you have arrived at the
customer site.
2
Have the customer take you to the unit with the faulty component.
3
Verify the appliance compute node serial number. The serial number is located on the rear panel
of the appliance and begins with the letters VTAS.

If the work order provides the 5U84 Storage Shelf serial number, verify that the serial number on
the work order matches the serial number on the storage shelf. The Veritas Serial Number label
is located in the lower right-hand corner of the shelf’s rear panel under the power supply. Do not
use the label in the upper left-hand corner for the Veritas Serial Number.
Removing the faulty disk drive carrier
Use the following procedure to remove the faulty disk drive carrier.
To remove the faulty disk drive carrier
1
