The Recovery Guru in SANtricity System Manager monitors the drives in the unit and can notify
you of an impending drive failure or an actual drive failure. When a drive has failed, its amber
Attention LED is on. You can hot-swap a failed drive while the unit is receiving I/O operations.
Before you begin
– You have a replacement drive that is supported by Bosch for the controller unit or
expansion unit.
– You have an ESD wristband, or you have taken other antistatic precautions.

Rules for handling drives
The drives are fragile. Improper drive handling is a leading cause of drive failure. Follow these
rules to avoid damaging the drives in your unit:
– Prevent electrostatic discharge (ESD)
– Keep the drive in the ESD bag until you are ready to install it.
– Do not insert a metal tool or knife into the ESD bag. Open the ESD bag by hand or
cut the top off with a pair of scissors.
– Keep the ESD bag and any packing materials in case you must return a drive later.
– Always wear an ESD wrist strap grounded to an unpainted surface on your storage
enclosure chassis. If a wrist strap is unavailable, touch an unpainted surface on your
storage enclosure chassis before handling the drive.
– Handle drives carefully
– Always use two hands when removing, installing, or carrying a drive.
– Never force a drive into a unit. Use gentle, firm pressure to completely engage the
drive latch.
– Place drives on cushioned surfaces, and never stack drives on top of each other.
– Do not bump drives against other surfaces.
– Before removing a drive, unlatch the handle and wait 30seconds for the drive to spin
down.
– Always use approved packaging when shipping drives.
– Avoid magnetic fields
– Keep drives away from magnetic devices. Magnetic fields can destroy all data on the
drive and cause irreparable damage to the drive circuitry.
