System Update Use Case Scenarios

The following table provides use case scenarios about how system updates occur based on different protocols and the update modes.
  • NOTE: If the preferred system update method selected in Advanced Settings is In-Band (Operating System) and OpenManage Server Administrator (OMSA) is installed on the target server, the components are updated using OMSA. If OMSA is not installed on the target server, the components are updated through the operating system.
Table 1. System Update Use Case Scenarios. The following table provides use case scenarios about how system updates occur based on different protocols and the update modes.
Protocol Used for Server IP Discovery and Inventory Protocol Used for iDRAC IP Discovery and Inventory Preferred System Update Mode Selected in Advanced Settings Credentials for System Update Actual Update Mode
SNMP SNMP In-Band (Operating System) Server All components are updated using OpenManage Server Administrator.
  • NOTE: When an iDRAC IP is discovered using SNMP, iDRAC software inventory is not retrieved and all components are updated are using Server Administrator irrespective of the preferred system update mode selected.
SNMP SNMP Out-of-Band (iDRAC) Server
WMI SNMP In-Band (Operating System) Server All components are updated using OpenManage Server Administrator.
WMI SNMP Out-of-Band (iDRAC) Server All components are updated using Server Administrator because the protocol used for iDRAC discovery and inventory was SNMP.
WMI SNMP In-Band (Operating System) Server All components are updated using the operating system.
SSH WS-Man/SNMP In-Band (Operating System) Server All components are updated using the operating system.
SNMP WS-Man In-Band (Operating System) Server All components are updated using OpenManage Server Administrator.
SNMP WS-Man Out-of-Band (iDRAC) iDRAC BIOS, firmware, and applications are updated using iDRAC.
  • NOTE: When an iDRAC IP is discovered using WS-Man, the iDRAC software inventory is retrieved and the components are updated using iDRAC.
However, if drivers are present in addition to BIOS, firmware, and applications, then all the components are updated using Server Administrator and not iDRAC.
WMI WS-Man In-Band (Operating System) Server All components are updated using OpenManage Server Administrator.
WMI WS-Man Out-of-Band (iDRAC) iDRAC BIOS, firmware, and applications are updated using iDRAC.
  • NOTE: When an iDRAC IP is discovered using WS-Man, the iDRAC software inventory is retrieved and the components are updated using iDRAC.
However, if drivers are present in addition to BIOS, firmware, and applications, then all the components are updated using Server Administrator and not iDRAC.
WS-Man (ESXi-based server) WS-Man (ESXi-based server) In-Band (Operating System) iDRAC All components are updated using iDRAC. For ESXi-based servers, all components are updated using iDRAC , irrespective of preferred system update mode selected.
WS-Man (ESXi-based server) WS-Man (ESXi-based server) Out-of-Band (iDRAC) iDRAC
Not applicable. The server IP is not discovered. WS-MAN In-Band (Operating System) iDRAC All components are updated using iDRAC.
Not applicable. The server IP is not discovered. WS-MAN Out-of-Band (iDRAC) iDRAC
