require a system restart are applied at the time of restarting the server. Updates are performed in

batches at the scheduled time using iDRAC. The batch size is determined when the update is

happening. The appliance assumes that the update is successful, as soon as iDRAC reports that the

update is successful. The status of the updates are not logged in the appliance after the job is

submitted to iDRAC. Hence refresh the inventory to check if all the updates are applied. The entire

update job fails if the operation fails on even one server.

– Agent-free updates — is out of band update with immediate server restart.

You can view the update groups in the update center page. The description and behavior of the update

groups are as follows:

• Generic update groups

– All update groups

– Default unassigned server update groups

• Cluster update groups

• Host update groups

– Default host update groups

• Chassis update groups

Generic update groups — this group consists of hosts and unassigned servers that are updated in a single

session.

All update groups — this group consists of all the server groups. Any group present in the appliance is a

member of the all update group. This group is of type generic update group.

Default unassigned server update group — this group consists of all the unassigned servers that are not

part of any other group. This group is of type generic update group. The servers are added to default

unassigned server update group after:

• A fresh discovery or rediscovery of bare metal servers.

• A synchronization or resynchronization, after it is deleted from SCVMM but present in the appliance.

Cluster update group — this group consists of Windows Server Failover clusters. If a modular server

belongs to a cluster, then it is added to cluster update group. If a 12th generation or 13th generation of

Dell PowerEdge modular server is part of cluster then, the CMC information is also added in the inventory

in Update Center page.

To know the cluster update group to which a server belongs to, see the device inventory page where the

hostname and cluster FQDN is displayed for all servers listed in the appliance.

Host update group — this group consists of host servers, and updates are applied in a single session.

Wherein, the single session pertains to updating all servers within the group at once.

Default host update group — this group consists of all the discovered hosts that are not part of any other

update group. This group is of type host update group.

Chassis update group — Modular servers belonging to a chassis and not part of any cluster group are

classified as chassis update group. 12th generation, or 13th generation of Dell PowerEdge servers are

discovered along with their CMC information. By default, a group is created with the naming format —

Chassis-Service-tag-of-Chassis-Group for example, Chassis-GJDC4BS-Group. If a modular server is

deleted from a cluster update group, then the server is added to chassis update group along with its CMC

information. Even if there are no modular servers in the corresponding chassis update group, since all
