Rolling back firmware
If you are not convinced with the firmware update of a device or component, you can roll back the update to the version before
the update. The rollback option is enabled only if OME–Modular can access the firmware package of the previous version. The
following methods can be used to enable the access:
● A Device that has the rollback version (or N-1 version) that matches the previous version. Not all devices support a rollback
or N-1 version. The rollback version is displayed as a rollback candidate even if it does not match the version before the
update.
● An imported catalog that has a reference to the previous catalog version.
● You can browse for a firmware package that has the previous firmware version.
For Network IOMs, the availability of rollback information depends on the status of the Network IOM (Full Switch or Fabric) and
the firmware update method. If the firmware is updated on nodes in the fabric, the rollback information is available on the node
on which the firmware update is initiated. If the firmware on the member chassis Network IOMs is updated through the Lead
chassis, the rollback information is available on only on the Lead chassis.
To roll back a firmware update:
1. On the Firmware page, click Rollback Firmware.
The Rollback Firmware window is displayed.
2. Select the component for which you want to roll back the firmware and click Rollback.
NOTE: The device is always updated with individual DUP and is never updated or downgraded as part of catalog or
baselines. But, when the device is associated with any baseline and an update is available as part of that catalog or
baseline, by default the catalog option is given for the Rollback as it is a secure option.
Deleting firmware
You can delete firmware baselines, if you have the administrator privilege.
To delete a firmware baseline:
On the Firmware page, select the baseline that you want to delete, and click Delete.
A message is displayed prompting you to confirm the delete operation.
