Read all precautionary notes, kit instructions, and other information. Kit
instructions often contain the most current information regarding the drives
and their installation, plus upgrade or servicing procedures. Compare the kit
instructions with this procedure to determine if you need to modify this
procedure.
2. Use the DS4000 Storage Manager software to check the status of the unit.
Correct any problems that are reported.
3. Use the DS4000 Storage Manager software to ensure that the installed
DS4000 controller and EXP100 ESM have the minimum controller and ESM
firmware versions that are required for the new SATA drive. Always check the
documentation that is included with the new drive to find out the minimum
controller and ESM firmware versions, or any prerequisite tasks, for DS4000
controller and EXP100 ESM.
4. Back up the data in the arrays and logical drives that are configured using the
drives that you are replacing.
Attention: When you handle static-sensitive devices, take precautions to
avoid damage from static electricity. For details about handling static-sensitive
devices, see “Handling static-sensitive devices” on page 30.
5. Put on the antistatic strap and unpack the new drives.
Set the drives on a dry, level surface away from magnetic fields. Save the
packing material and documentation in case you need to return the drives.
6. Use the DS4000 Storage Manager software to ensure that the array that was
defined using these drives is in optimal (not degraded) state before manually
failing the first drive you want to replace. If the array is in degraded state, use
the recovery procedures to bring the array into the optimal state.
Make sure that:
v You fail only one drive
v The software status display shows a failed status for the appropriate drive
v
The amber Drive fault LED (on the front bezel below the drive) is on
Attention: Removing the wrong drive can cause data loss. Make sure that
you remove only the failed drive CRU. The Drive fault LED below the failed
drive CRU should be on.
If you remove an active drive accidentally, wait at least at least 70 seconds
and then reinstall it. Because you failed two drives in a RAID array, the array
might be marked failed by the controller. This array will not be available to the
host for I/O. Contact IBM support for further recovery instructions. Do not
attempt to replace any drives until the array is brought back to optimal state.
7. Use the procedures in “Replacing hot-swap hard disk drives” on page 76 to
remove the failed drive. Use the procedures in “Installing hot-swap hard disk
drives” on page 74 to install the new drives into the EXP100.
The new drive automatically reconstructs the data after you install it in the
drive slot.
During data reconstruction, the amber Drive fault LED might come on for a few
minutes, 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 your 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.
