Update firmware using OMIMSSC
Maintain Dell EMC devices up-to-date by upgrading to the latest firmware to use security, issue fixes, and enhancements, using
OMIMSSC. Update the firmware of devices using Dell EMC update repositories.
Updating firmware is supported only on hardware compatible devices. For using the features available in OMIMSSC on the
managed devices, the managed devices must have the minimum required firmware versions of iDRAC, Lifecycle Controller (LC),
and BIOS. Devices having the required firmware versions are hardware compatible.

About update groups
Update groups are a group of devices that require similar update management. There are two types of update groups that are
supported in OMIMSSC:
● Predefined update groups—You cannot manually create, modify, or delete the predefined update groups.
● Custom update groups—You can create modify and delete devices in these groups.
NOTE:
All server groups that exist in SCVMM are listed in OMIMSSC. However, the list of servers in OMIMSSC is not
user-specific. Therefore, ensure that you have access to perform any operations on those devices.
Predefined update groups
After discovering a device, the discovered device is added to one of the following predefined groups.
● Default host groups—this group consists of servers that are deployed with Windows operating system or are synchronized
with a registered Microsoft console.
● Default unassigned groups—this group consists of unassigned or bare-metal servers discovered.
● Default non-windows host groups—this group consists of servers that are deployed with non-windows operating
systems.
● Chassis update groups—this group consists of modular servers and chassis or Modular Systems. 12
th
generation of
servers and later are discovered along with their chassis information. By default, a group is created with the following name
format, Chassis-Service-tag-of-Chassis-Group. For example, Chassis-GJDC4BS-Group. If a modular server
is deleted from a cluster update group, and 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.
● Cluster update groups—this group consists of Windows Server Failover clusters. If a 12
th
generation and later modular
server is part of cluster, and then the CMC information is also added in the inventory in the Maintenance Center page.
Custom update groups
Create custom update groups of type Generic update groups by adding the discovered devices into groups that require similar
management. However, you can add a device into a custom update group only from Default unassigned update groups and
Default host update groups. To add the servers in custom update group, search for the required device using their service
tag. After you add a device into a custom update group, the device is removed from the predefined update group and is
available, only in the custom update group.
