HXDP Release 5.5(1a) Upgrade Error on M4 Servers
Description
Starting with Cisco HyperFlex Release 5.5(1a), M4 servers are not supported. Attempts to upgrade clusters containing M4 or earlier HX generation servers to HXDP Release 5.5(1a) or later will fail in the pre-upgrade phase.
The upgrade and activity pages display an error in the Bootstrap Upgrade step. In some cases, the user is unable to view the error message and is shown a successful upgrade whenin reality the upgrade has failed.
The fallback mechanism is to display a ClusterUpgradeFailed event along with a banner stating that the attempted upgrade is disallowed.
Symptom
An alert is generated and a banner appears stating that One or more M4 platform nodes was detected in the cluster which is not supported starting HXDP 5.5(1a). Please follow the graceful node removal procedure to remove these nodes from the cluster or work with TAC to migrate from these nodes and retry the upgrade.
Note |
The message center is populated with the same error message. |
Action
Gracefully remove the upsupported nodes and retry the upgrade or contact TAC for further assistance.
