IBM TotalStorage FAStT600, Installation And User Manual

ensures that the FAStT600 Storage Server and all its attached drive enclosures
will have power if only one power circuit is available. In addition, having all the
right or all the left power supplies plug into the same power circuit will enable the
components in the storage subsystem to power on simultaneously during an
unattended restoration of power. See Figure 32 on page 34 for an example of
redundant power connections.
v
Before any planned system shutdown or after any system changes (additions,
removals, or modifications), save controller subsystem profiles as explained in
the Storage Manager guide for your operating system.
v Ensure that your system is in an optimal state before shutting down. Never turn
the power off if any fault light is lit; be sure to resolve any error conditions before
you shut down the system.
v
During any maintenance or attended power-up procedure, carefully follow the
power-up sequence listed in “Turning on the storage server” on page 38. Each
component of the subsystem should be checked that it is powered-on in the
proper order during this entire power-up procedure to ensure the controller will be
able to optimally access all of your storage subsystems.
v
The storage subsystem supports simultaneous power-up to the system
components; however, you should always follow the power-up sequence listed in
“Turning on the storage server” on page 38 during any attended power-up
procedure.
v A storage system in an optimal state should recover automatically from an
unexpected shutdown and unattended simultaneous restoration of power to
system components. After power is restored, call IBM support if any of the
following conditions occur:
– The storage subsystem logical drives and arrays are not displayed in the
Storage Manager graphical user interface (GUI).
– The storage subsystem logical drives and arrays do not come online.
– The storage subsystem logical drives and arrays seem to be degraded.
Storage server components
The following sections show the components of the storage server.
The hot-swap features of the storage server enable you to remove and replace hard
disk drives, power supplies, RAID controllers, and fans without turning off the
storage server. Therefore, you can maintain the availability of your system while a
hot-swap device is removed, installed, or replaced.

server.
