Manager Version 10.8 Installation and Host Support Guide (for DS Storage Manager
V10.83 or later) for the applicable host operating system. The document is in the
Documentation folder on the IBM System Storage DS3500 Support DVD.
Important:
Obtain the following information about your storage subsystem and components:
v Determine whether you have a single-controller storage subsystem or a
dual-controller storage subsystem. For details, see “DS3500 storage subsystem
overview” on page 2. See Figure 7 on page 13 for an illustration of a
single-controller storage subsystem.
v See the topic “Checking the LEDs” on page 88 to understand how to check the
status lights on the LED panel.
v Check the MAC addresses of the host ports after replacing the controller and/or
the host port interface adapter. If you need to change the MAC address, update
the servers or switches in the configuration.
Attention:
v Ensure that both power supplies are connected and powered-on and no amber
LEDs are lit. If the status of either of the power supplies is not Optimal, replace
that power supply before you proceed with the controller replacement
procedure.
v If you are replacing a failed controller, you need to determine the capacity of the
DIMM it contains. There are two methods to determine the capacity of the
DIMM in a failed controller:
– When you remove the failed controller you can look at the label on the
DIMM to see if it isa1GBor2GBDIMM.
– Use the Storage Manager Client. You can view the controller cache size either
on the controller properties screen (found in the Physical tab) or by viewing
the storage subsystems profile. Refer to the IBM System Storage DS Storage
Manager 10 Installation and Host Support Guide for your host operating system,
for guidance on how to install the Storage Manager Client program, and to
make Management connections to the Storage subsystems after its installation.
Also, refer to the illustrations for reference.
To replace a controller in a storage subsystem, complete the following steps:
1. Read the safety information that begins on page “Safety” on page ix and “Best
practices guidelines” on page 8. See “Checking the LEDs” on page 88 for an
illustration of the LED panel.
2. Use the Storage Manager software to print a storage subsystem profile. See
Chapter 4, “Operating the storage subsystem and storage enclosure,” on page
81 for more information.
v In a dual-controller storage subsystem, move the logical drive ownership to
the other controller.
v If the controller that you are replacing is still operating, move the failed
controller to the offline state.
Attention: Never remove a controller unless the OK to remove LED is lit.
Doing so can result in a loss of data.
3. Locate the failed controller by checking the amber LEDs on the controllers in
the storage subsystem.
