Guidelines
To replace the storage controller with a controller of a different model, reconfigure RAID after the
replacement. For more information, see the storage controller user guide for the server.
To replace the storage controller with a controller of the same model, make sure the following
configurations remain the same after replacement:
• Storage controller operating mode.
• Storage controller firmware version.
• BIOS boot mode.
• First boot option in Legacy mode.
For more information, see the storage controller user guide and the BIOS user guide for the server.
Preparing for replacement
To replace the storage controller with a controller of the same model, identify the following
information before the replacement:
• Storage controller location and cabling.
• Storage controller model, operating mode, and firmware version.
• BIOS boot mode.
• First boot option in Legacy mode.
To replace the storage controller with a controller of a different model, back up data in drives and
then clear RAID information before the replacement.
Procedure
The replacement procedure is the same for storage controllers of different models. This section uses
the RAID-LSI-9361-8i(1G)-A1-X storage controller as an example.
To replace a storage controller:
1. Power off the server. For more information, see "Powering off the server."
2. Disco
nnect external cables from the riser card that holds the storage controller.
3. Remove the riser card. For more information, see "Replacing a riser card and PCIe module at
the serve
r rear."
4. Disconnect cables from the storage controller.
5. Remove the storage controller. For more information, see "Replacing a riser card and PCIe
module at the
server rear."
6. Remove the power fail safeguard module as needed. For more information, see "Replacing the
power fail saf
eguard module for a storage controller."
7. Install the removed power fail safeguard module to a new storage controller as needed. For
more information, see "Replacing the power fail safeguard module for a storage controller."
8. Install the ne
w storage controller. For more information, see "Installing storage controllers and
power fail saf
eguard modules."
9. Install the riser card that holds the storage controller. For more information, see "Installing riser
cards a
nd PCIe modules at the server rear."
10. Connect the external cables to the riser card.
