The Dell iDRAC SUP0108 error indicates a "deployment or update operation is already in progress," often triggered by a hung process, stuck RAM drive, or a false positive during firmware updates. Resolution typically involves resetting the iDRAC, clearing the job queue, or performing a cold boot to clear stuck, temporary data. For detailed troubleshooting, see the official Dell Knowledge Base. iDRAC10 Version 1.20.25.00 Release Notes
The error code SUP0108 ("A deployment or update operation is already in progress") is a common message encountered on Dell PowerEdge servers, typically within the iDRAC (Integrated Dell Remote Access Controller) or Lifecycle Controller. It indicates that the system believes a firmware update or deployment task is currently running and will not allow a new one to start until the current one finishes. Why it Happens
This message often appears even when no operation is actively visible. Common causes include:
Stuck RAM Drive: The iDRAC firmware installer creates a temporary RAM drive on the host OS to run updates; if it doesn't clear properly, subsequent updates are blocked.
Active Lifecycle Controller: The system may falsely report the Lifecycle Controller is in use during driver mounting or other UI tasks.
Pending Job Queue: A previous job may be "scheduled" or "running" in the background job queue. Best Ways to Resolve SUP0108
Perform an iDRAC Reset (Soft Reset)This is the quickest fix and does not affect the host operating system.
Action: Log into the iDRAC web interface, navigate to the Maintenance tab, and select Diagnostics > Reset iDRAC.
Alternative: Use the RACADM command-line tool with the command: racadm racreset. Clear the Job QueueStuck jobs can block the update engine. Action: In the iDRAC UI, go to Maintenance > Job Queue.
Action: Select and delete any jobs that are not "Completed" or "Failed." You can also use racadm jobqueue delete -i JID_CLEARALL.
Perform a Cold Boot (Power Drain)If a soft reset fails, a physical power cycle is often necessary to clear the hardware's temporary state.
Action: Shut down the server and disconnect all power cables.
Action: Press and hold the power button for at least 30 seconds to drain residual power, then reconnect and restart.
Wait Out the RAM Drive (18 Hours)If you cannot perform a cold boot immediately, the temporary RAM drive created by the installer is designed to clear itself automatically after approximately 18 hours.
Update iDRAC FirmwareDell has released firmware versions (such as iDRAC9 v7.20.10.50) that specifically resolve bugs where the update job fails to start or reports incorrect "busy" statuses.
Are you seeing this error while manually uploading a file or while using the Lifecycle Controller at startup? iDRAC10 Version 1.20.25.00 Release Notes The Dell iDRAC SUP0108 error indicates a "deployment

ecosystem. It indicates that the system is currently occupied with a firmware update or deployment task and cannot start a new one. Understanding SUP0108 Definition : A deployment or update operation is already in progress. : Warning. Common Trigger
: Attempting to mount a driver or start a firmware update while the Lifecycle Controller is active or a background task is running. Troubleshooting & Resolution
If you encounter this error, follow these steps to clear the block: Wait for Completion
: The most standard solution is to wait for the current operation to finish. Some updates, particularly for iDRAC 9, can take anywhere from 20 minutes to 4 hours to fully conclude. Clear the Job Queue
: If the operation appears stuck, you can manually clear the iDRAC job queue: Connect to the iDRAC via using a client like Log in with your root credentials. Execute commands to delete existing jobs (e.g., racadm jobqueue delete -i JID_CLEARALL Perform a Cold Boot
: In some cases, a previous upgrade leaves a "RAM drive" on the host OS that must be cleared. A Cold Power-Off
(removing power completely) or a system reboot will reset this state. Reset iDRAC
: You can reset the iDRAC interface through the web UI under Maintenance > Diagnostics
or by holding the "i" button on the front of the server for 16 seconds. Best Practices to Avoid SUP0108 Avoid Heavy CPU Load
: Refrain from firmware updates when the CPU is under heavy utilization, as this can impact fan speeds and cooling. Sequential Updates
: Ensure one update job has moved from the "Downloading" or "Extracted" state to "Completed" before initiating another. OS-Based Updates
: If the LCC interface is consistently buggy, consider running the update directly from the Host Operating System using the Dell Update Package (DUP). iDRAC10 Version 1.20.25.00 Release Notes - Dell
An "error SUP0108" usually pops up in systems like SAP Commerce Cloud (formerly Hybris) when you try to trigger a deployment or update while another task is already hogging the queue. It’s essentially the system's way of saying, "One thing at a time, please." 1. The Core Conflict
The system uses a lock mechanism to prevent data corruption. If two updates happen at once, they could overwrite each other’s configurations or database schemas. When you see SUP0108, the Cloud Portal or the API has detected an active "Running" or "Processing" status on a previous request. 2. Common Culprits To understand this error, you must understand the
The Ghost Process: A previous deployment failed or timed out, but the system never "flipped the switch" to mark it as finished.
Parallel Team Efforts: Another developer or an automated CI/CD pipeline triggered a build without you realizing it.
Environment Initialization: If the environment is currently being initialized or wiped, all other update operations are blocked. 3. How to Resolve It
Check the Deployment Dashboard: Navigate to your Cloud Portal and look at the Deployment History. Look for any task with a status of "Scheduled," "In Progress," or "Cancelling."
Wait for the Timeout: Sometimes, the system just needs 15–30 minutes to realize a process has stalled and auto-terminate the lock.
Manual Cancellation: If you have the permissions, manually cancel the stuck deployment. Once the status moves to "Failed" or "Cancelled," the SUP0108 block should lift.
API Verification: If the UI is lagging, use the Cloud Management API to GET the status of the environment. This often provides a more "real-time" look at what's actually running. 4. Best Practices to Avoid Recurrence
Sequential Workflow: Ensure your Jenkins or GitHub Actions pipelines are set to "wait" or "fail fast" if a build is already active.
Clear Communication: Use a shared Slack or Teams channel to notify the team before hitting "Deploy" on shared staging environments.
Are you seeing this error in a production environment or a development/sandbox environment?
The error SUP0108: A deployment or update operation is already in progress is a common informational or warning message encountered on Dell PowerEdge servers using the iDRAC (Integrated Dell Remote Access Controller) or Lifecycle Controller.
It essentially means the system believes a firmware update or deployment task is already running, which prevents you from starting a new one. Common Causes
Stuck Job Queue: A previous update job may be stuck in a "Downloading" or "Scheduled" state.
Pending iDRAC Operations: The Lifecycle Controller might still be processing a background task, even if no active progress bar is visible.
Residual Lock Files: A failed update might have left behind a "lockfile" on the iDRAC RAM drive, which incorrectly signals that a process is still active. blocking all future actions.
Recent Firmware Changes: Updates to iDRAC 9 (versions prior to 7.00.60.00) sometimes fail to clear their own internal status if a file transfer times out. Best Ways to Resolve SUP0108 If you encounter this error, try these solutions in order:
Wait and Retry: In some cases, the iDRAC just needs time to finish extracting files or cleaning up its internal RAM drive. Wait at least 15–20 minutes before trying again. Clear the iDRAC Job Queue: Log into the iDRAC web interface. Navigate to Maintenance > Job Queue. Delete any stuck or failed jobs.
Reset the iDRAC: This is a safe, non-disruptive way to clear "ghost" operations without rebooting the entire server.
In the iDRAC web interface, go to the Dashboard and select Reset iDRAC.
Alternatively, hold the "i" button on the front of the server for about 16 seconds until the fans spin up.
Perform a "Cold Boot": If the error persists due to a stuck lockfile on the RAM drive, a full power cycle (unplugging the server for 30 seconds) will force a clean state.
Force Clear via RACADM: If you have command-line access, use the following Dell RACADM command:racadm jobqueue delete -i JID_CLEARALL_FORCE. Pro Tip for Future Updates
To avoid this issue, experts recommend performing updates through the iDRAC Web Interface using local files rather than the Lifecycle Controller (F10) boot menu, as it is generally more stable and easier to monitor.

ERROR running force:mdapi:deploy: SUP0108: A deployment or update operation is already in progress. Please wait for the current operation to complete before starting a new one.
To understand this error, you must understand the architecture of ConfigMgr and WSUS.
The error SUP0108: A deployment or update operation is already in progress (best) occurs when the WSUS server is already executing a command (like synchronizing, cleaning up, or declining updates) when ConfigMgr asks it to start a new operation.
The word "(best)" in the log refers to the WBSearchJob or a best-effort attempt by the WSUS API to handle concurrent requests. It essentially means: "I would love to help you, but I am already running another critical job. Please wait."
WSUS needs regular database maintenance. Use a scheduled script to run the WSUS Server Cleanup Wizard weekly via PowerShell to prevent database bloat that leads to locks.
Frequently, the previous operation has technically completed (success or failure), but the extension service status on the VM has not updated to a "Ready" state. This leaves a semaphore/lock file in place on the local agent, blocking all future actions.
