Dynamic configuration of virtual addresses, initiator, and storage target settings

You can dynamically view and configure the virtual address, initiator and storage target settings, and apply a persistence policy. It allows the application to apply the settings based on power state changes (that is, operating system restart, warm reset, cold reset, or AC cycle) and also based on persistence policy setting for that power state. This provides more flexibility in deployments that need rapid re-configuration of system workloads to another system.

The virtual addresses are:
  • Virtual MAC Address
  • Virtual iSCSI MAC Address
  • Virtual FIP MAC Address
  • Virtual WWN
  • Virtual WWPN
  • NOTE: When you clear the persistence policy, all the virtual addresses are reset to the default permanent address set at the factory.
  • NOTE: Some cards with the virtual FIP, virtual WWN, and virtual WWPN MAC attributes, the virtual WWN and virtual WWPN MAC attributes are automatically configured when you configure virtual FIP.
Using the IO Identity feature, you can:
  • View and configure the virtual addresses for network and fibre channel devices (for example, NIC, CNA, FC HBA).
  • Configure the initiator (for iSCSI and FCoE) and storage target settings (for iSCSI, FCoE, and FC).
  • Specify persistence or clearance of the configured values over a system AC power loss, cold, and warm system resets.

The values configured for virtual addresses, initiator and storage targets may change based on the way the main power is handled during system reset and whether the NIC, CNA, or FC HBA device has auxiliary power. The persistence of IO identity settings can be achieved based on the policy setting made using iDRAC.

Only if the I/O identity feature is enabled, the persistence policies take effect. Each time the system resets or powers on, the values are persisted or cleared based on the policy settings.

  • NOTE: After the values are cleared, you cannot re-apply the values before running the configuration job.
