19 Upgrading Memory in the E2600 Controller Canisters
Each controller canister in the E2600 controller-drive tray has one cache memory DIMM and
one cache backup memory device. Use this procedure to add a larger capacity cache memory
DIMM and add a larger capacity cache backup memory device to the controller canisters in
the E2600 controller-drive tray
Before you start this procedure, gather antistatic protection, cache memory DIMMs, and
cache backup memory devices.
This procedure describes how to perform the following tasks.
1. Section 19.1 Removing the Controller Canisters from the E2600 Controller-Drive Tray,
page 139
2. Section 19.2 Upgrading the Cache Memory DIMM, page 142
3. Section 19.3 Upgrading the Cache Backup Memory Device, page 144
4. Section 19.4 Reinstalling the Controller Canister in the E2600 Controller-Drive Tray,
page 144
5. Section 19.5 Turning On Power to the Controller Canisters in the E2600 Controller-Drive
Tray, page 145
19.1 Removing the Controller Canisters from the E2600 Controller-
Drive Tray
1. If possible, use the storage management software to create, save, and print a current
storage array profile.
2. Use the Locate function in the storage management software to identify the controller
canisters to upgrade (see Figure 19.1 ).
CAUTION!
Data loss or corruption might result if the steps in this upgrade procedure are not followed
correctly
You must upgrade the cache memory DIMMs and the cache backup memory devices in both
controller canisters in the E2600 controller-drive tray. Otherwise, you will receive event
messages indicating that the controllers have mismatched and incompatible configurations.
NOTICE!
Do not perform this upgrade procedure with the power turned on. This procedure requires
that you first set controller A offline to make sure that of all the data, which is currently in
cache on both controller canisters, is successfully written to disk before the upgrade. Second,
you will turn the off the power to both controller canisters as described in the steps for
Section 19.1 Removing the Controller Canisters from the E2600 Controller-Drive Tray, page 139 .
NOTICE!
Before you remove the controller canisters, make sure you set controller A offline, as
described in the following steps, to make sure that all the data currently in the cache in
controller A is successfully written to disk before the upgrade. This step also makes sure that
the data currently in the cache in controller B is successfully written to disk before you turn
off the power to both of the controller canisters.
CAUTION!
Possible hardware damage
To prevent electrostatic discharge damage to the tray, use proper antistatic protection when
handling tray components.
