The New Reservation page contains a form for creating a new reservation.
Reservation Settings
Use this section of the form to specify information about and specifications for your reservation.
Name
(Optional) Lets you specify the name of the reservation.
Description
Lets you specify a text description of the reservation.
Lets you determine which of the following settings (if any) should be applied to the reservation. You may include as many or as few of these settings as you want.
| Setting | Description |
|---|---|
| Dedicated resources | Specifies that no other tasks will take placed on the server where this reservation exists. The reservation's resources will not be shared, regardless of whether or not the reservation is being actively used. |
| Evacuate workload from selected nodes when the reservation starts |
Specifies that you want to evacuate workload from this reservation's nodes before this reservation begins. This option will cause Moab to automatically evacuate VMs from this reservation's nodelist. When you select this option, the Node Count configuration in the Resources section becomes unavailable. 
Sometimes, Moab may refuse to migrate one or more of the VMs off of the reserved node and will generate an error with the message: "Unable to find destination for VM '<name>' (Reservation, Attributes)." "Attributes" refers to the fact that Moab cannot find an eligible machine based on the datacenter attribute requirement.
If you choose this option and the any of the affected VMs is on the Migration Exclusion list (see Configuring the Migration Exclusion policy for more information), Viewpoint returns an error message. To resolve this, you must first remove the VM(s) from the list or disable the policy and then create the reservation with the Evacuate workload option. |
Access Controls
In this section of the form, you can grant access to this reservation to Moab users, accounts, and groups. You can also specify the user, account, or groups' job affinity toward the reserved resources.
To add additional access controls to the reservation, choose Add (
). To remove access controls, choose Remove (

Lets you specify if the access setting applies to Moab user, group, or account. Choose one of the following:
| Option | Description |
|---|---|
| User | Specifies that the access control applies to a Moab user. |
| Account | Specifies that the access control applies to a Moab account. |
| Group | Specifies that the access control applies to a Moab group. |

Name
Depending on the Type, lets you specify the exact name of the Moab user, account, or group.
You must be careful to enter exact names or the users, accounts, and groups you specify will not be allowed access to the reservation.
Affinity
Lets you specify the Moab user, group, or account's affinity to the reservation. Choose one of the following:
| Option | Description |
|---|---|
| Positive | Specifies that the user, group, or account's jobs tend toward the reservation, causing the job to use the reservation's resources and leave other unreserved resources free for use by other jobs that may not have access to the reservation. |
| Negative | Specifies that the user, group, or account's jobs avoid the reservation. The reservation's resources are used only as a last resort. |
| Neutral | Specifies that the user, group, or account's jobs are neither attracted nor repelled by the reservation's resources. These jobs may or may not be given resources from the reservation. |
