Users Guide

• You have the Login, Configure, and System Control privileges.
• BIOS, iDRAC, and network cards are updated to the latest firmware. For information on the supported versions, see Supported BIOS
Version For I/O Identity Optimization and Supported NIC Firmware Version for I/O Identity Optimization.
After enabling I/O Identity Optimization feature, export the XML configuration file from iDRAC, modify the required I/O Identity attributes
in the XML configuration file, and import the file back to iDRAC.
For the list of I/O Identity Optimization attributes that you can modify in the XML configuration file, see the NIC Profile document
available at delltechcenter.com/idrac.
NOTE: Do not modify non I/O Identity Optimization attributes.
Enabling or Disabling I/O Identity Optimization Using Web Interface
To enable or disable I/O Identity Optimization:
1. In the iDRAC Web interface, go to Overview > Hardware > Network Devices.
The Network Devices page is displayed.
2. Click the I/O Identity Optimization tab, select the I/O Identity Optimization option to enable this feature. To disable, clear this
option.
3. Click Apply to apply the setting.
Enabling or Disabling I/O Identity Optimization Using RACADM
To enable I/O Identity Optimization, use the command:
racadm set idrac.ioidopt.IOIDOptEnable Enabled
After enabling this feature, you must restart the system for the settings to take effect.
To disable I/O Identity Optimization, use the command:
racadm set idrac.ioidopt.IOIDOptEnable Disabled
To view the I/O Identity Optimization setting, use the command:
racadm get iDRAC.IOIDOpt
Configuring Persistence Policy Settings
Using IO identity, you can configure policies specifying the system reset and power cycle behaviors that determine the persistence or
clearance of the virtual address, initiator, and storage target settings. Each individual persistence policy attribute applies to all ports and
partitions of all applicable devices in the system. The device behavior changes between auxillary powered devices and non-auxillary
powered devices.
You can configure the following persistence policies:
• Virtual Address: Auxiliary powered devices
• Virtual Address: Non-Auxiliary powered devices
• Initiator
• Storage target
Before applying the persistence policy, make sure to:
• Inventory the network hardware at least once, that is, enabled Collect System Inventory On Restart.
• Enable I/O Identity Optimization.
Events are logged to the Lifecycle Controller log when:
• I/O Identity Optimization is enabled or disabled.
• Persistence policy is changed.
• Virtual address, initiator and target values are set based on the policy. A single log entry is logged for the configured devices and the
values that are set for those devices when the policy is applied.
Event actions are enabled for SNMP, email, or WS-eventing notifications. Logs are also included in the remote syslogs.
