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

groups. This group is of the 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 the type generic update group. The servers are added to the 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 the 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 the

Maintenance Center page.

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

FQDN is displayed for all the 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 is

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 the 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 the chassis update group along with its CMC

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

are in a cluster update group, the chassis update group continues to exist, but displays only the CMC information.

Custom update groups

You can create, modify and delete the custom update groups. However, you can add a server into a custom update group only from

Default unassigned update groups and Default host update groups. After you add a server into a custom update group, the server

is removed from the predefined update group and this server is available only in the custom update group. To add the servers in

custom update group, search for the servers using their service tag.

Updating methods

You can apply selected updates to selected server groups that are compliant.

• You can perform the following updates on server groups:

– Agent-free staged updates — is staging of firmware updates. The firmware updates that are immediately applicable and

that do not require a restart are applied immediately. The remaining updates that require a system restart are applied at the
