Users Guide

You can create an update source or a repository, and set it as a default update source for generating a comparison report, and
receiving alerts when new catalog files are available at the repository.
Using OMIMSSC, you can keep the devices firmware up-to-date using online or offline update sources.
Online update sources are repositories that are maintained by Dell EMC.
Offline update sources are local repositories and used when there is no Internet connection.
It is recommended that you create custom repositories and place the network share in the local intranet of OMIMSSC Appliance.
This would save the Internet bandwidth and also provide a secure internal repository.
Update firmware using one of the following update sources:
● DRM repository—is an offline repository. Export the inventory information of discovered devices from OMIMSSC
Appliance to prepare a repository in DRM. For information about integration with DRM, and creating an update source
through DRM, see Integration with DRM. After creating a repository in DRM, in OMIMSSC, select the update source that
is created through DRM, relevant devices, and initiate an update on the devices. For information about DRM, see Dell
Repository Manager documents available at dell.com\support.
● HTTPS—can be an online or offline repository. Update specific components of devices with respect to the latest update
provided on HTTPS site. Dell EMC prepares a repository at every two months cadence and publishes the following updates
through PDK catalogs:
○ Server BIOS and firmware
○ Dell EMC certified operating system driver packs—for operating system deployment
NOTE: If you select an online update source, while deploying the Operational Template, the latest firmware versions
are downloaded and applied on the managed devices. Hence, the firmware versions might differ between reference and
deployed device.
● Reference firmware inventory and comparison—can be converted to an offline repository through DRM. Create a
reference inventory file that contains the firmware inventory of the selected devices. The reference inventory file can
contain inventory information of a device of the same type or model, or can have multiple devices of different types or
models. You can compare the inventory information of devices present in OMIMSSC against the saved reference inventory
file. To pass the exported file to DRM and create a repository, see Dell Repository Manager documents available at
dell.com\support.
Predefined and default update source
OMIMSSC includes the predefined update source that is available after a fresh installation, or upgrade. DELL EMC
ENTERPRISE CATALOG is a predefined default update source of type HTTPS. However, you can create another update
source and mark it as a default update source.
NOTE:
If you are using proxy server, to access the repository, edit the update source to add the proxy details and save the
changes.
