Overview

Follow the procedures for your environment (upgrading

one or multiple storage systems):

•Upgrading a single storage system—Continue

with “Installing the memory module” (page 1).

•Upgrading multiple storage systems in a

management group—To save restripes of volume

data, HP recommends shutting down the

management group, which puts it into

maintenance mode. Then you can upgrade

multiple storage systems and safely restart all the

storage systems to bring the management group

back online. See “Safely shutting down a

management group” (page 3) and then follow

the steps in “Installing the memory module”

(page 1).

Installing the memory module

1. Have the following items ready:

•Memory module

•T-10 wrench

2. Power down the storage system, using the CMC:

a. Log in to the storage system.

b. Right–click the storage system and select

Power Off or Reboot.

c. In the window that opens, select Power off.

Alternatively, you can power down the system by

quickly pressing and releasing the storage system

power button two times.

3. Extend the storage system from the rack:

a. Disconnect all peripheral cables and power

cords.

b. Loosen the front panel thumbscrews.

c. Extend the storage system on the rack rails

until the storage system rail-release latches

engage.

WARNING! To reduce the risk of

personal injury or equipment damage,

be sure that the rack is adequately

stabilized before extending a

component from the rack.

4. Remove the storage system from the rack and

place it on a sturdy, level surface.

5. Use a wrist strap connected to the work surface,

and properly grounded (earthed) tools and

equipment.

6. Remove the top cover:

a. Loosen the screw on the top cover with a

T-10 wrench (1).

b. Press the latch on the top cover (2).

c. Slide the cover toward the rear of the server

and then lift the top cover to remove it from

the chassis. Lift the top cover away from the

chassis (3).

7. Remove the air baffle:

a. Gently rock the air baffle up.

b. Take the air baffle out from the system board.

8. Find the DIMM slot for installing the new DIMM.

For P4500 G2 MDL SAS Storage products, this

is slot 6C. For all other models, it is slot 4B.

9. Install the memory module:

a. Align the notch on the bottom edge of the

memory module with the keyed surface of

the DIMM slot.

b. Fully press the memory module into the slot

until the holding clips snap back in place.

CAUTION: The DIMM slots are structured

to ensure proper installation. If you insert

a DIMM but it does not fit easily into the

slot, you may have inserted it incorrectly.

Reverse the orientation of the DIMM and

insert it again.

10. Gently place the air baffle back on the system

board.

11. Reinstall the top cover:

a. Align the top cover to the chassis and then

slide it towards the front panel to position it

reconnect the cables.

c. Reconnect all peripheral cables and power

cords.

13. Power on the storage system.

Safely shutting down a management group

1. Disconnect any hosts or servers that are accessing

volumes in the management group.

2. Wait for any restriping of volumes or snapshots

to complete.

3. Stop managers on storage systems that you plan

to remove from the management group. You may

want to add a FOM or start a Virtual Manager

on a different storage system to maintain quorum

and the best fault tolerance. See the section

“Stopping Managers” in the HP StoreVirtual

Storage User Guide.

4. Log in to the management group to shut down.

5. Click Management Group Tasks on the Details

tab, and select Shut Down Management Group.

6. Click Shut Down Group.

After you click Shut Down Group, a confirmation

window opens, listing volumes that are still

connected and that will become unavailable if

you continue shutting down the management

group. If this window opens, do the following:

a. Stop server or host access to the volumes in

the list.

b. Click Shut Down Group.

Restarting the management group

When you are ready to restart the management group,

simply power on the storage systems for that group:

1. Power on the storage systems that were shut

down.

2. Click Find→Find Systems in the CMC to discover

the storage systems.

When the storage systems are all operating

properly, the volumes become available and can

be reconnected to the hosts or servers.

See the HP StoreVirtual Storage User Guide or Online

Help in the Centralized Managment Console for more

information.
