After rebooting the 8880 appliance the management port becomes inaccessible.
This only occurs on hardware appliances capable of operating in dual inline mode.
The SEDR appliance is using dual inline mode and after rebooting the 8880 network interface's alias mapping is incorrect.
This will be resolved in a future release of SEDR.
Please contact support for assistance in resolving this issue in a remote support session. Remote access through iDRAC will be required.
