Replacing An Ac Power Supply - IBM DS3500 Installation, User's, And Maintenance Manual

During data reconstruction, the amber drive fault LED might be lit for a few minutes and then turn
off when the green drive activity LED begins flashing. A flashing drive activity LED indicates that
data reconstruction is in progress.
Note: If the storage subsystem has active hot spares, data might not start copying to the new drive
until the data is reconstructed on the hot spare. This increases the time that is required to complete
the procedure.
7. Check the green drive activity LED and the amber drive fault LED on each of the new drives.
Make sure that the drive activity LEDs are lit and the drive fault LEDs are off.
Note: The drive fault LEDs might flash intermittently while the drives spin up.
v If the drive activity LED is off, the drive might not be installed correctly. Remove the drive, wait
70 seconds, and then reinstall it.
v If the drive fault LED stays lit or the drive activity LED stays off, the new drive might be faulty or
might be an uncertified drive. Use the Storage Manager software for problem determination. In
the case of an uncertified drive, make sure that the drive options or drive FRU part number is
correct for the storage subsystem.
8. Use the Storage Manager software to monitor the status of the new drive and the progress of the
data reconstruction. Wait for data reconstruction to finish (the drive activity LED stops flashing).
Note: The drive activity LED continues to flash after reconstruction is finished if there is I/O activity
to that drive. In that case, use the host software to determine whether the data reconstruction is
finished.
9. When reconstruction is finished on the new drive, repeat step 5 on page 5-20 through step 8 for each
additional drive that you want to install.
10. Use the Storage Manager software to configure the additional space on the new drives.
