HP StorageWorks Controller Enclosure 4Gb Array Controller Replacement Instructions (631505-001, August 2010)

1. Halt I/O to the controller with HP Command View EVA:
a. In the navigation pane, select Storage System > Hardware >
Controller Enclosure.
b. Select the appropriate controller (Controller 1 or Controller 2)
to halt.
c. Click the Shut down tab.
d. In the Halt Controller section of the Shut Down Controller
window, click Halt. This halts controller processing while the
power remains on.
NOTE:
In the rare instance when you cannot halt I/O to
the controller, go to Shutting down the controller
enclosure to shut down the controller enclosure.
Otherwise, continue with Step 2. If you shut down
the controller enclosure, all I/O is halted.
In addition, exercise care when replacing a
controller while the enclosure is powered off to
ensure that inadvertent controller software
upgrades or downgrades will not occur.
2. Disconnect the Fibre Channel cables from the halted controller.
Ensure they are marked to facilitate reconnecting later.
3. Remove the controller.
a. Move the mounting latch to the right (1, Figure 3). The controller
will slightly eject from the enclosure.
b. Position one hand under the controller, and with the other hand,
pull the controller out of the enclosure (2).
