Make sure that:
v You fail only one drive
v
The software status display shows a Failed status for the applicable drive
v
The amber drive fault LED (on the front bezel below the drive) is lit
Attention: Removing the wrong drive can cause data loss. Make sure that
you remove only the failed drive. A lit drive fault LED indicates the failed drive.
If you remove an active drive accidentally, wait at least 70 seconds and then
reinstall it. Because you have failed two drives in a RAID array, the array might
be marked as failed by the controller. This array will not be available to the
host for I/O. See the DS3000 Storage Manager software for further recovery
instructions. Do not attempt to replace any drives until the array is brought
back to Optimal state.
6. Use the procedures in “Replacing a hot-swap hard disk drive” on page 72 to
remove the failed drive. Use the procedures in “Installing a hard disk drive” on
page 71 to install the new drives in the storage subsystem.
The new drive automatically reconstructs the data after you install it in the
drive bay.
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 DS3000
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 DS3000 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 77
through step 8 for each additional drive that you want to install.
10. Use the DS3000 Storage Manager software to configure the additional space
on the new drives.
