Users Guide

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.
• FTP, HTTP, or HTTPS—can be an online or offline repository. Update specific components of devices with respect to the latest
update provided on FTP, HTTP, or 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.

CATALOG is a predefined update source of type FTP, DELL ONLINE HTTP CATALOG is a predefined update source of type HTTP,
and DELL ONLINE HTTPS 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.
