By default, 8880 appliances ship with the os to IDRAC connection disabled by default. Within the DRAC UI, this setting appears in IDRAC settings > Network > "OS to IDRAC Passthrough."
Symantec doesn't support the IDRAC feature to be enabled. Disable IDRAC.
Please disable "OS to IDRAC Passthrough" to prevent unplanned changes to the hostname of the 8880 appliance.
