Using the Dell Hybrid Cloud System for Microsoft data
consistency runbooks
Dell Hybrid Cloud System for Microsoft includes runbooks that you can use to detect and, in some cases, to automatically recover from
data inconsistencies between the databases of the components that are deployed as part of Dell Hybrid Cloud System for Microsoft.
Specically, the Invoke-DataConsistency runbook (and its associated child runbooks) detects and tries to recover from inconsistencies
between components’ states.
Dell recommends that you use the Dell Hybrid Cloud System for Microsoft data consistency runbooks for detection and recovery after you
restore a management component database from backup. For example, you may have restored a database to x data corruption. The
detection runbooks can report inconsistencies between the Windows Azure Pack, SPF, and VMM database components, that is, objects
associated with the VM Cloud Resource Provider.
The detection runbooks can report inconsistencies between the Windows Azure Pack, SPF, and VMM database components, that is,
objects associated with the VM Cloud Resource Provider.
Overview of the data consistency master and child runbooks
The data consistency runbooks include a master runbook, which in turn triggers a set of child runbooks.
The master runbook, Invoke-DataConsistency, is the main runbook to use for detection and recovery. When you run it, you must specify a
subsystem. This triggers the associated child runbooks for that subsystem. To understand what the subsystem targets, see the information
in the following table.

Virtual Machine Provider
(VMProvider)
Detection: Test-VmCloudsDataConsistency
Detects and reports inconsistencies between the Windows Azure Pack,
SPF, and VMM database components, that is, objects associated with the
VM Cloud Resource Provider. This runbook can detect the following
issues:
For VMM:
• "Object not found" for cloud, hardware prole, VM network, VM
template and user role
• "Out of sync" for user role quota, user role network settings, and user
role virtual machine permissions
• Other – Logical networks not added to the cloud.
For SPF:
• "Object not found" for Gallery item, stamp, and tenant
• "Out of sync" for tenant status.
NOTE: Out of sync indicates that the properties in the
component are out of sync with the properties that are set on
the plan, subscription or add-on.
Recovery: Repair-VmCloudsDataConsistency
Tries to automatically recover issues with plans, add-ons and
subscriptions. Also reports issues that the runbook cannot x, where
manual recovery may be required.
