Upgrading a single-controller to a dual-controller when there is no
attached EXP3000 enclosure
If you are upgrading a single-controller DS3200 storage subsystem to a
dual-controller DS3200 storage subsystem and there are no EXP3000 storage
expansion enclosures attached to the DS3200 storage subsystem, see “Installing a
controller” on page 64.
Upgrading a single-controller to a dual-controller when there is one or
more EXP3000 enclosures attached to the storage subsystem
Before you upgrade the DS3200 storage subsystem from a single-controller to a
dual-controller, make sure that:
v You purchase a second environmental services module (ESM) for each EXP3000
storage expansion enclosure that is attached to the DS3200 storage subsystem.
You install the second ESM during this procedure.
v You purchase the SAS cables that are required to create a redundant drive
enclosure path.
To upgrade a single-controller DS3200 storage subsystem to a dual-controller
DS3200 storage subsystem when there are EXP3000 storage expansion enclosures
attached to the DS3200, complete the following steps:
1. Turn off the DS3200 storage subsystem and all attached EXP3000 storage
expansion enclosures.
2. Install a second RAID controller in the DS3200 storage subsystem by using the
instructions in “Installing a controller” on page 64.
3. Install a second ESM in each EXP3000 that is connected to the DS3200
storage subsystem:
a. Read the safety information that begins on page xi and “Best practices
guidelines” on page 6.
b. Remove the ESM filler panel from the rightmost ESM bay of the EXP3000:
1) On the left side of the ESM filler panel, press the orange release tab to
the right just enough to release the handle (no more than 6 mm
[0.25 in.]) as you rotate the handle upward.
2) Using the handle, gently slide the ESM filler panel out of the EXP3000.
Save the ESM filler panel for future use.
c. Hold the new ESM so that the handle is fully extended.
d. Gently slide the ESM into the bay until it stops. Rotate the handle downward
into the closed position until it clicks.
4. Using the information provided in “DS3200 storage subsystem drive cabling
topologies” on page 28, use SAS cables to create a redundant drive-channel
path from the DS3200 RAID controllers to the EXP3000 ESMs.
Connecting secondary interface cables
This section applies to direct (out-of-band) management configurations only. If your
configuration uses host-agent (in-band) management, skip this section.
Use the Ethernet management port on the rear of the storage subsystem to connect
the controllers for direct management of the storage subsystems (see “Direct
(out-of-band) management method” on page 36).
