v Do not leave the device where others can handle and possibly damage the
device.
v While the device is still in its static-protective package, you should hold the
device and touch an unpainted metal part of the system unit for at least two
seconds. This drains static electricity from the package and from your body.
v Remove the device from its package and install it directly into your system unit
without setting it down. If it is necessary to set the device down, place it in its
static-protective package. Do not place the device on your system unit cover or
on a metal table.
v
Take additional care when handling devices during cold weather because heating
reduces indoor humidity and increases static electricity.
Best practices guidelines
To ensure optimal operation of your system, always follow these best practices
guidelines:
v Back up the data on your storage drives periodically.
v
Before any planned system shutdown or after any system changes (additions,
removals, or modifications), save controller subsystem profiles as explained in
the IBM DS4000 Storage Manager Installation and User’s 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 subsystem” on page 92.
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 subsystem” on page 92 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.
v
Using the DS4000 Storage Manager client, save the DS4000 subsystem
configuration profile to a disk that is not affected every time you make changes to
the DS4000 subsystem configuration (such as logical drive creation or
modification, or storage partitioning changes).
v DS4300 Model 60U/60X only: To maintain power redundancy, plug the DS4300
dual-controller storage subsystem’s right and left power supplies into two
independent external power circuits through ac distribution units inside a rack
cabinet or directly into external receptacles. Similarly, the right and left power
supplies of the DS4000 storage expansion enclosures attached to the DS4300
storage subsystem should be plugged into the same two independent external
power circuits as the DS4300 storage subsystem. This ensures that the DS4300
