Ensure that you save the files in a location other than in the logical drives,
which were created for the storage system.
For more information about how to complete these tasks, check the IBM DS
Storage Manager online help or the IBM DS Storage Manager guide for your
operating system.

During any maintenance or attended power on procedure, carefully follow the
power on sequence listed in “Restoring power after an unexpected shutdown”
on page 73. Ensure that each component of the system is powered on in the
correct order, so that the controller can optimally access all the storage systems.
v
The storage system supports simultaneous power on to the system components.
However, you must always follow the power on sequence listed in “Restoring
power after an unexpected shutdown” on page 73.
v
A storage system in an optimal state should recover automatically from an
unexpected shutdown and an unattended restoration of power to system
components. After power is restored, call IBM support if any of the following
conditions occur:
– The storage system logical drives and systems do not display in the DS
Storage Manager graphical user interface (GUI).
– The storage system logical drives and systems are not online.
– The storage system logical drives and systems are degraded.
DCS3860 components
The DCS3860 storage system directs and manages the I/O activity between a host
and the drives in a RAID array. The EXP3800 expansion unit provides additional
storage capacity to the storage system.
