Installation

Rack requirements:

HP supports the HP System E racks and the

HP 10000 Series racks for use with the virtual

library system (VLS). Other racks might also be

suitable, but have not been tested with the VLS.

Caution: Make sure that the rack and all

equipment mounted in the rack has a

reliable ground connection. Verify that the

total current of the rack components does

not exceed the current rating of the power

distribution unit or outlet receptacles.

Caution: Parts can be damaged by

electrostatic discharge. Keep parts in their

containers until needed. Ensure that you

are properly grounded when touching

static sensitive components.

Inspect the box contents.

You will also need a

Phillips screwdriver.

Warning: The MSA20 disk array

weighs 24 kg (53 lb) full. At least two

people are required to lift and rack mount

the disk array.

Warning: To reduce the risk of personal

injury or damage to the equipment, before

installing equipment be sure that:

•The rack leveling jacks are extended to

the floor.

•The full weight of the rack rests on the

leveling jacks.

•The stabilizing feet are attached to the

rack if it is a single-rack installation.

•The racks are coupled together in

multiple-rack installations.

•Only one component is extended at a

time. A rack may become unstable if

more than one component is extended

for any reason.

HP recommends that you mount the disk arrays

in the following order.

1 Disk array 4

2 Disk array 3

3 Node

4 Disk array 1

5 Disk array 2

Note: If the VLS node is not installed, install and

cable it before installing the disk array(s). See the

HP StorageWorks 6000 Virtual Library System

Node Installation poster.

Power down the node

If you are adding a disk array to an operating

VLS, power down the node. If not, skip this step.

To power down the node:

1. Verify that any backup or restore operation has

completed and that the VLS is idle.

2. Open a serial session and log in as the

administrator as follows:

a. Connect a PC or workstation to the serial port

on the rear of the VLS using the null-modem

serial cable provided.

b. Establish a CLI session using a terminal

emulation program, such as Windows

Hyperterminal.

c. Enter administrator for the username.

d. Enter admin for the password.

3. Initiate a shutdown of the VLS by entering:

shutdownSystem and then press Enter

4.When the VLS has completed its shutdown

operation, press the node Power On/Standby

button to place the node in standby mode.

When the node activates standby power mode,

the system power LED changes to amber.

If you are installing a capacity bundle or an

existing disk array to the VLS base configuration,

install the capacity license for the additional

disk array following the instructions in the

HP StorageWorks 6000 Virtual Library System

User Guide. Otherwise, skip this step.

Note: The VLS 2.5TB capacity bundle

contains an MSA20 disk array and the

capacity license for the disk array. If you

want to add an existing MSA20 disk

array to the VLS, you must purchase the

capacity license for the disk array

separately.

Note: As an option, you can add an

additional disk array to the VLS before

installing its capacity license. However, a

capacity violation will occur when the VLS

node is powered up, disabling the VLS

storage capacity so that the VLS is unable

to perform read/write operations. Later,

when the capacity license is installed and

the VLS is rebooted, the VLS storage

capacity is re-enabled.

5Use the 2U rack mounting template as a guide to indicate

where on the rack the rails for the disk array are to be

mounted.

a. At the front of the rack, with the front of the template facing

you, align the lower edge of the template with the bottom

of the rack (or the top of the previous rack component). Be

sure that the lower edge of the template is level.

b. Push the template tabs into the holes in the rack uprights to

hold the template in place.

c. Use a permanent marker pen to indicate the holes in the

rack uprights into which the scissor-like locking latches are

to be inserted, as specified by the template.

d. Repeat these steps to mark the back of the rack, using the

information on the back of the template as a guide to the

required location of the locking latches in this case.

Warning: The pins in the rails are

load-bearing. Do not remove the pins

except to replace them with the pins for

round-hole racks.

If the holes in the rack uprights are round

instead of square, remove the standard pins from

the rails and replace them with the round-hole

pins provided in the rack mounting hardware kit.

Identify the left (L) and right (R) rack rails by

markings stamped into the rails.

Slide the front end of the right rack rail toward

the inside front of the rack until the locking latch

engages with the marked hole in the front rack

upright.

Extend the back end of the rail toward the inside

rear of the rack until the locking latch engages

with the marked hole in the rear rack upright.

Loosen the locknut on the shipping bracket, and

move the bracket to the rearmost position on the

rail. Repeat steps 6 and 7 for the left rack rail.

Cabling

Connect the AC input socket of each disk array

power supply to an AC power source.

Hardware installation is complete. You may now

power up the disk array(s) and then the node as

described in the HP StorageWorks 6000 Virtual

Library System User Guide.

Connect the VHDCI connector on the disk array to

the appropriate VHDCI connector on the node as

shown.

1. VHDCI connector A1, connect to disk array 1

2. VHDCI connector A2, connect to disk array 2

3. VHDCI connector B1, connect to disk array 3

4. VHDCI connector B2, connect to disk array 4

Align the disk array with the rails, and slide it

into the rack.

Remove the

mounting

bracket

covers, and

tighten the

thumbscrews

to secure the

disk array to

the rack.

Replace the

mounting

bracket

covers.
