Single frame configurations with redundant Composers and only a single frame link module
CAUTION:
A single
frame link module failure causes the Active
Composer to restart unexpectedly which causes a failover to the Standby
Composer. Such a failure is also observed during a
frame link module firmware update that requires a restart of the
frame link module. To bring this configuration into a fully redundant configuration, add an additional
frame link module.
A single frame configuration with two Composers and a single frame link module does not provide full redundancy and is not a supported configuration for use in production environments.
If you must perform a frame link module firmware update while operating with a single frame link module, perform a Remove standby action in HPE OneView prior to updating the firmware. Once the frame link module firmware update completes, bring the Standby Composer back into the cluster by powering on the Composer.
