Clearing disk configuration in Bios

Scope

BDA Administrators and ACS

Details

On BDA there is no RAID on the controller and the controller is just used to do basic JBOD disk configuration, wiping out the configuration does not necessarily mean that data is lost and reimaging is needed.

If the disks can be reconfigured/re-added one at a time in the correct order (lowest to highest slot, without wiping) then the BDA should be able to continue using OS disks as before with no reimaging or reformatting needed.

If below steps are performed for all 12 disks one at a time in the correct order (lowest to highest slot) and without selecting any options to wipe/initialize the disk then it should be possible to restore the node.

Highlight “[-] LSI MegaRAID”, press F2, choose Create Virtual drive.
Select a single drive by checking only one check box followed by OK and OK.

Here are detailed instructions to ADD ALL drive/disks back to the controller in Bios Configuration screen

1) Enter CTRL-R during boot to enter Bios Configuration screen

Enter Bios Screen

2) In VD Mgmt screen

3) Highlight "LSI MegaRAID..." and press F2 operations

Add VD in Bios

4) Click on 'Create Virtual Drive'

Note:- Disks need to be added from lowest to highest slot number . Also only ONE disk needs to be configured at a time in order to restore previous data and partitions.

a) Use down Arrow to select disk in slot 0 (or whatever the first slot the disk is un-configured) then click enter
b) Then use down arrow to select OK which is next to Advanced
c) There is a pop up which states initialization is not being performed and attempting to restore previous configuration . Click ok
Add VD in Bios

5) After adding a disk the screen goes to 'VD Mgmt' . In 'VD Mgmt' it will list the disks configured so far.

In below image only disk in slot0 is currently configured

Add VD in Bios

6) Scroll up and highlight "LSI MegaRAID..." and press F2 operations

7) Follow instructions from step4 above to add the next 'Create Virtual Drive'

8) Once adding ALL the disks 'Create Virtual Drive' option will no longer be highlighted

9) Click on 'Ctrl-Alt-Delete' from the ILOM Menu on the top off the screen to reboot the node

10) Once the node is booted into OS mode below commands can be executed to check the disk state

mount -l

ls -l /dev/disk/by-label
