Last Modified: Jun 19, 2025

Affected Product(s):
F5OS F5OS-C(all modules)

Known Affected Versions:
F5OS-C 1.6.2, F5OS-C 1.8.0, F5OS-C 1.8.1

Opened: Feb 22, 2025

Severity: 3-Major

Symptoms

The 'cluster reboot' command does detect if a blade is present in the chassis before attempting to reboot it. It takes 5 to 10 seconds to issue the reboot, regardless of whether the blade exists, and this operation is performed sequentially across all blades assigned to the partition.

Impact

The 'cluster reboot all' command can take several minutes to complete and report status.

Conditions

Empty/unused chassis slots assigned to a partition.

Workaround

Using the chassis CLI or UI, assign empty/unused blade slots to partition 'none'.

Fix Information

None
