Rebuild the RAID 1 boot device using the replaced M.2 module
The BOSS device consists of two 120/240 GB M.2 expansion cards. If necessary, rebuild the M.2 cards as a RAID 1
device.
Procedure
1. Power on the node.
2. In the iDRAC Virtual KVM console, press F2 immediately after you see the message F2 = System Setup
during system start up.
3. On the System Setup Main Menu screen, select Device Settings > AHCI Controller in Slot 2: BOSS-S1
Configuration Utility.
4. On the BOSS-S1 Configuration Utility screen, select Physical/Virtual Disk Information to verify the disk
configuration.
5. On the BOSS-S1 Configuration Utility > Operation Menu screen, select Physical Disk Info as the Device
Output Type, and then press Enter.
The physical disk information should display two expansion card devices configured to the server.
6. Select Virtual Disk Info as the Device Output Type, and then press Enter.
The configuration should show one virtual disk in a degraded RAID state configured on the server.
7. Click Back.
8. On the BOSS-S1 Configuration Utility screen, select Rebuild Raid.
You can monitor the status of the rebuild in the Storage > Virtual Disks screen. During the rebuild, the status of
the M.2 will be displayed as Degraded.
When the M.2 array is rebuilt, its status will be similar to the following:

l
RAID Level: RAID1
l
Stripe Size: 64 K
l
Virtual Disk Size: 111/222 GB (The size will correspond to the M.2 device in use.)
