Job queued. Reboot for the BIOS setting to take effect.
```
**If `racadm` is not installed** — which is the normal case on a plain
Proxmox host — the script prints two manual options:
```
racadm not found.
Option A: Run from iDRAC SSH:
ssh root@<idrac-ip>
racadm set BIOS.StorageSettings.HddSeq Enabled
racadm jobqueue create BIOS.Setup.1-1
# Then reboot to apply.
Option B: iDRAC web UI:
System BIOS → Power Management → Hard Disk Drive Sequencing → Enabled
Apply and reboot.
```
**Use Option A (iDRAC SSH)** — it is the reliable one. The web UI path is
buried deep and the wording varies between firmware versions.
SSH directly to iDRAC using the static IP you set in Phase 2:
```bash
ssh root@192.168.1.5
```
(Enter the iDRAC root password you set in Phase 2.)
You will land in iDRAC's own shell — not the Proxmox shell. The prompt
looks like:
```
/admin1->
```
Run the two racadm commands:
```
racadm set BIOS.StorageSettings.HddSeq Enabled
racadm jobqueue create BIOS.Setup.1-1
```
Expected output for each:
```
/admin1-> racadm set BIOS.StorageSettings.HddSeq Enabled
[Key=BIOS.Setup.1-1#StorageSettings]
RAC1017: Successfully modified the object value and the change is in
pending state.
/admin1-> racadm jobqueue create BIOS.Setup.1-1
RAC1024: Successfully scheduled a job.
Verify the job status using "racadm jobqueue view -i JID_xxxxxxxxxxxx"
Commit JID = JID_123456789012
Reboot Required = Yes
```
Type `exit` to leave the iDRAC shell. You are now back on the Proxmox
host.
The BIOS setting is **queued** but not yet applied — the server must POST
once for it to take effect. The next reboot (Step 10.6 will trigger one)
will apply it automatically.
> **Why not reboot right now?** Because we are about to install the Linux
