Sup0108 A Deployment Or Update Operation Is Already In Progress Best Fixed -

The error code is a standard message within the Dell iDRAC and Lifecycle Controller (LCC)

Go to Setup → Deployments (or Outbound Change Sets).
Look for any deployment with status In Progress, Pending, or Validating.
Abort or wait for completion.

Confirm downtime/impact window is acceptable.
Notify stakeholders and pause new deployment triggers.
Check monitoring/alerts for active progress (CPU, logs, network).
Back up any critical state (DB snapshot, config export).
Use read-only queries where possible to inspect state.
