Use this recovery method if your management node experienced
hardware failures that required you to replace a solid state drive
(SSD) or an SSD and the hard disk drive.
Before you begin
Before you perform the following
management software reinstallation
procedure, make sure that you have replaced the failed SSD (and hard
disk drive, if applicable) and returned the management node to its
default configuration.
For more information about removing and replacing
solid state drives and hard disk drives, see the relevant topics in Installing, removing, and replacing components.
To complete the
management software recovery
process, you need the following items:
About this task
This procedure returns the management node and management software to
factory defaults, and destroys all of your data on the management
node. Therefore, you must complete the initial setup again after the
recovery is complete.
Note: If the hot-swap SAS drive has failed,
but the solid state drives have not, the IBM Flex
System Manager management software image
might still be operational.
Important: The RAID
reconfiguration that is described in step
1 is necessary only if you have replaced
a failed hard disk drive or both of the SSDs. If only one SSD has
failed and been replaced, the RAID is restored automatically.
Procedure
- If you replaced only one SSD, skip
to step 2. If you replaced both SSDs, a hard
disk drive, or all three, you must reconfigure the RAID. During the
restart of the management node (after the splash screen), start the
LSI Corp Configuration Utility and reconfigure the RAID settings:
- When the following message is displayed on your screen,
press Ctrl+C.

- Select the adapter and press Enter.
- Select SAS Topology and press
Enter.
- Expand Direct Attach Devices so
that the hard disk is displayed.
- Make sure that the hard disk is set as the alternate
boot device, or Alt, and that the RAID is set to Boot.
If Alt and Boot are not displayed,
use the following key combinations to modify the configuration:
- Alt+B: Select or deselect a device as the preferred boot
device.
- Alt+A: Select or deselect a device as the alternate boot
device.
- Press Escape; then, select Save changes then
exit this menu and press Enter.
- Press Escape; then, select Exit the Configuration
Utility and Reboot and press Enter. The
management node restarts.
- Install
the console breakout cable in
the front of the management node.
- Connect the external optical media drive to the console breakout cable.
- Insert Recovery DVD 1 in the external DVD drive; then,
start the management node.
- After the management node boots, select Recover
the management node; then, press Y.
- From the menu, select the second option in the list: Recover
complete system (use if both SSDs failed, or to update a down-level
recovery partition) for management software version
1.2.1 or later,or Destroy
and remake all partitions for versions 1.2.0 and earlier.
After you make the selection, press Y.
- When you are prompted, select Yes to
confirm that you want to reinstall the management software.
Attention: After you confirm that you want to proceed
with the reinstallation, all of your data on the management node will
be destroyed.
- When you are prompted, remove the Recovery DVD 1 and insert
the Recovery DVD 2 in the external optical drive.
Note: After
you insert Recovery DVD 2, wait approximately one minute before you
press Enter. If you press Enter and the DVD is ejected, reinsert the
DVD and wait two minutes before you press Enter again.
Depending
on the version of IBM Flex
System Manager management software you
are recovering, you might have more than 2 DVDs to insert. If so,
continue with this step for each of the DVDs.
- When you are prompted, disconnect the external DVD drive.
Note: After all of the DVDs have been copied, you might receive
an "unknown error." If that occurs, press Enter.
Then, select Exit and allow the system to restart.
- The management node reboots. When the firmware splash screen
is displayed, press F12. The setup menu is displayed. The screen displays confirmation that
F12 has been pressed.
- Select Full system recovery. After approximately 30 to 45 minutes, the recovery process
ends and the Management Server Setup wizard opens.
Note: The system
displays Loading Bootloader, but no additional messages are displayed
during the recovery process. If the screen saver is activated and
the screen goes blank during this stage, press the Shift key to deactivate
the screen saver.
- Either complete the Management Server Setup wizard or restore
a previous configuration from a backup.
Note: To restore
from backup, you must have previously saved the backup on either a
USB drive or secure FTP server.
