Handling static-sensitive devices
Attention: Static electricity can damage electronic devices and your system. To
avoid damage, keep static-sensitive devices in their static-protective packages until
you are ready to install them.
To reduce the possibility of electrostatic discharge (ESD), observe the following
precautions:
v Limit your movement. Movement can cause static electricity to build up around
v Handle the device carefully, holding it by its edges or its frame.
v Do not touch solder joints, pins, or exposed printed circuitry.
v Do not leave the device where others can handle and damage it.
v While the device is still in its static-protective package, touch it to an unpainted
v Remove the device from its package and install it directly into the system unit
Adding new hard disk drives
This section describes the procedure to add new hard disk drives to empty drive
bays either in storage subsystems or storage enclosures. If you plan to add a used
drive, ensure that there is no configuration data on the drive that you need to
preserve. A used drive is a drive that is removed from an existing storage
subsystem. It might be configured as part of the RAID array. Add drives to a
storage subsystem only while the power is turned on and the storage subsystem is
in Optimal state. For more information, see "Bringing storage subsystems and
drive loops into optimal state" on page 11.
Important:

DS Storage Manager software version 10.xx or later. (For information about the
type of logical drives that can be migrated, see item "Verifying controller,
NVSRAM, and ESM firmware compatibility" on page 4.) However, you cannot
migrate drives from systems with controller firmware version 7.xx or later to
systems with controller firmware level 6.xx or earlier.
Ensure that the controller firmware level of both the source and target storage
subsystems. Upgrade both the source and target storage subsystems to the same

back into its static-protective package. Do not place the device on the system
unit cover or on a metal surface. Take additional care when you handle devices
during cold weather. Heating reduces indoor humidity and increases static
electricity.
