• VMware Cloud Director

Issue/Introduction

• "A specified parameter was not correct: key" error when resizing a single disk on a virtual machine in VMware Cloud Director versions 10.3.x, 10.4 and 10.4.1.
• The storage policy is set to unlimited, so no quotas are applied.
• The backend datastore provides enough space for the resizing operation.
• The /opt/vmware/vcloud-director/logs/vcloud-container-debug.log shows errors of the form:

| ERROR    | task-service-activity-pool-3855 | SdrsApiInvocationManagerImpl   | SDRS cancelRecommendation error: A specified parameter was not correct: key | requestId=<REQUEST_UUID>,request=POST https://vcloud.example.com/api/vApp/vm-<VM_UUID>/action/reconf...,requestTime=1668518510774,remoteAddress=<IP>:56789,userAgent=Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 ...,accept=application/*+xml;version 38.0.0-alpha vcd=<VDC_UUID>,task=<TASK_UUID> activity=(com.vmware.vcloud.backendbase.management.system.TaskActivity,urn:uuid:<TASK_ACTIVITY_UUID>)

   faultCause = null,
   faultMessage = null,
   invalidProperty = key
}

Environment

VMware Cloud Director 10.3.x
VMware Cloud Director 10.4.0 and 10.4.1

Cause

This issue can occur if Cloud Director requests that a recommendationKey key is removed in vCenter but this recommendationKey key no longer exists in vCenter.

Such recommendationKey keys are part of SDRS reservations which are either timed out automatically by vCenter or cleared on request.
If Cloud Director believes that a key is still present but vCenter has already removed it then this error can occur.

Resolution

This is a known Issue in VMware Cloud Director 10.3.x, 10.4 and 10.4.1.
The issue resolved in 10.4.2-GA.

If you are unable to upgrade to 10.4.2, contact Broadcom Support and note this Article ID (312279) in the problem description. For more information, see Creating and managing Broadcom support cases.
