→ Applies to: Hyperion 9.x and above
IMPORTANT
Drives should only be forced to JBOD state if it is certain that they do not belong to an existing RAID configuration on another controller, as this operation may cause data loss.
Symptom
Disks transferred from an alternative RAID controller or another system are not detected by SynetoOS. When checking the drive information via the MegaRAID StorCLI, the affected drives are marked as UGood (Unconfigured Good) instead of JBOD, preventing the system from mounting or utilizing the storage pool.
Solution
Step 1. Connect to Hyperion appliance via SSH as admin
ssh admin@<your_ip_address_or_hostname>
Step 2. Become Super User
sudo su
Step 3. Check disks
lsblk -o NAME,SERIAL,SIZE,TYPE,MOUNTPOINTEXAMPLE OUTPUT
[root@syneto-os-backups]# lsblk -o NAME,SERIAL,SIZE,TYPE,MOUNTPOINT NAME SERIAL SIZE TYPE MOUNTPOINT sda EDE8N5097IOA01R05 447.1G disk ├─sda1 512M part /boot/efi ├─sda2 2G part /boot └─sda3 195.3G part / sdc 31336119 7T disk ├─sdc1 7T part └─sdc9 8M part sdd WBMA9E4H 2.2T disk ├─sdd1 2.2T part └─sdd9 8M part sde EDE8N5097IOA01R0I 447.1G disk ├─sde1 512M part ├─sde2 2G part └─sde3 195.3G part sdf 3133A916 7T disk ├─sdf1 7T part └─sdf9 8M part sdg WBMA9DKE 2.2T disk ├─sdg1 2.2T part └─sdg9 8M part zram0 4G disk [SWAP]
Step 4. Check disks configuration
/opt/MegaRAID/storcli/storcli64 /c0 /eall /sall showEXAMPLE OUTPUT
[root@syneto-os-backups]# /opt/MegaRAID/storcli/storcli64 /c0 /eall /sall show CLI Version = 007.3103.0000.0000 Aug 22, 2024 Operating system = Linux 5.14.0-503.38.1.el9_5.x86_64 Controller = 0 Status = Success Description = Show Drive Information Succeeded.

Step 5. Force the drive state to JBOD (replace <slot_number> with the correct information)
/opt/MegaRAID/storcli/storcli64 /c0 /e252 /<slot_number> set jbodEXAMPLE
/opt/MegaRAID/storcli/storcli64 /c0 /e252 /s6 set jbod /opt/MegaRAID/storcli/storcli64 /c0 /e252 /s7 set jbodRepeat this action for each slot missing the JBOD mode.
Step 6. Verify that the previously missing disks are now visible
