Restoring power after an unexpected shutdown The storage subsystem might shut down unexpectedly under any of the following conditions: Attention: There might be data loss in each of the following cases: IBM TotalStorage DS4300 Fibre Channel Storage Subsystem: Installation, User’s, and Maintenance Guide...
v The internal temperature of the storage subsystem exceeds the maximum operating temperature (an over-temperature condition). If both fan CRUs fail or are unable to maintain an internal temperature below 70°C (158°F), one or both of the power supplies in the storage subsystem will shut down.
In some cases (such as loss of redundancy in various components), the fault LED does not turn on. Only the storage-management software can detect the failure. IBM TotalStorage DS4300 Fibre Channel Storage Subsystem: Installation, User’s, and Maintenance Guide...
® For example, the recovery procedure for an IBM Predictive Failure Analysis (PFA) flag (impending drive failure) on a drive varies depending on the drive status (hot spare, unassigned, RAID level, current logical drive status, and so on). Depending on the circumstances, a PFA flag on a drive can indicate a high risk of data loss (if the drive is in a RAID 0 volume) or a minimal risk (if the drive is unassigned).

8. After you install all the new drives, check the system documentation for the hardware devices that you intend to power up, and then determine the proper startup sequence. Use the following power-on sequence, where applicable: a. Turn on the power to the supporting devices (for example, Ethernet switches and management stations) before you turn off power to the storage subsystem.
Page 156
7. Check the green Drive activity LED and the amber Drive fault LED below the new drive CRUs. Make sure that the Drive activity LEDs are on and the Drive fault LEDs are off. IBM TotalStorage DS4300 Fibre Channel Storage Subsystem: Installation, User’s, and Maintenance Guide...
Note: The Drive fault LEDs might flash intermittently while the drives spin up. v If the Drive activity LED is off, the drive CRU might not be installed correctly. Remove the drive CRU, wait 30 seconds, and then reinstall it. v If the Drive fault LED stays on or the Drive activity LED stays off, the new drive might be faulty.
The storage subsystem power system consists of two power supply CRUs. Exception: The DS4300 single-controller storage subsystem (Model 6LU/6LX) has only one power supply CRU. Therefore, you cannot hot swap the power supply. IBM TotalStorage DS4300 Fibre Channel Storage Subsystem: Installation, User’s, and Maintenance Guide...
The power supply CRUs provide power to the internal components by converting incoming ac voltage to dc voltage. One power supply CRU can maintain electrical power to the unit if the other power supply is turned off or malfunctions. The power supply CRUs are interchangeable (by reversing the locking levers).
4. Remove the nut and strain-relief clamp from the rear of the power supply. 5. Remove the power supply from the storage subsystem, as follows: a. Grasp the pull-ring on the power-supply lever and squeeze the latch to release it. IBM TotalStorage DS4300 Fibre Channel Storage Subsystem: Installation, User’s, and Maintenance Guide...
b. Pull the lever open and remove the power supply. Installing a hot-swap power supply Note: When you replace a power supply that has failed, ensure that the power supply latch is mounted on the side of the power supply that faces the middle of the storage subsystem.
