Best practices guidelines
IBM recommends guidelines or best practices for optimal operation of your system.
v
Ensure that your system is in an optimal state before you shut it down. Never
turn off the power if any Service Action Required LED is lit. Ensure that you
resolve any error conditions before you shut down the system.
v Back up the data on your storage drives periodically.
v
To maintain power redundancy, plug the right and left power supplies of the
DCS3860 storage system into two independent external power circuits through
the distribution units that are inside a rack cabinet or directly into external
receptacles. The DCS3860 storage system and all its attached expansion
enclosures can then have power in the event that only one power circuit is
available. Also, during an unattended restoration of power, the storage devices
in the configuration can power on simultaneously.
Note: Do not overload the circuits that power your storage system and storage
expansion enclosures. Use additional pairs of power distribution units (PDUs) if
necessary. Refer to Table 10 on page 20 for information about storage expansion
enclosure power requirements. Contact your IBM service representative for
additional information.
v
Before a planned system shutdown or after system additions, removals, or
modifications (including firmware updates, logical drive creations, storage
partitioning definitions, hardware changes, and so on), complete the following
tasks:
1.
Save the storage system profile.
2. Save the storage system configuration.
3. Save the Collect All Support Data (CASD).
