Best practices guidelines
To ensure optimal operation of your system, always follow these best practices
guidelines:
v Make sure that the storage subsystem is in an optimal state before you shut it
down. Never turn off the power if any amber LED is lit; be sure to resolve any
error conditions before you shut down the storage subsystem.
v Back up the data on your storage drives periodically.
v To maintain power redundancy, connect the DS3200 right and left power-supply
units to two independent external power circuits through ac power distribution
units (PDUs) inside a rack cabinet or directly into external receptacles. Similarly,
the right and left power supplies of the storage expansion enclosures (such as
the EXP3000) that are attached to the DS3200 should be connected to the same
two independent external power circuits as the DS3200. This ensures that the
DS3200 and all its attached storage expansion enclosures will have power in the
event that only one power circuit is available. In addition, having all the right or
all the left power cables connected to the same power circuit enables the
DS3000 devices in the configuration to power-on simultaneously during an
unattended restoration of power.
Note: Do not overload the circuits that power your storage subsystem and
storage expansion enclosures. Use additional pairs of ac PDUs. See
Table 1 on page 4 for information about storage subsystem power
requirements. Contact your technical-support representative for additional
information.
v Before any planned system shutdown or after any system additions, removals, or
modifications (including firmware updates, logical drive creations, storage
partitioning definitions, hardware changes, and so on), save the storage
subsystem profile as explained in the DS3000 Storage Manager Version 2
Installation and User's Guide for your operating system. Save the profile in a
location other than in the logical drives that are created for the DS3200.
v During any maintenance or attended power-on procedure, carefully follow the
power-on sequence that is described in “Turning on the storage subsystem” on
page 46. Make sure that each component of the storage subsystem is
powered-on in the correct order during this entire power-on procedure to make
sure that the controller will be able to optimally access all of the storage
subsystems.
v The storage subsystem supports simultaneous power-on to the system
components; however, you should always follow the power-on sequence that is
described in “Turning on the storage subsystem” on page 46 during any attended
power-on procedure.
