FlexAddress Feature State in CMC Disabled IO Identity Feature Availability of State in iDRAC Remote Agent VA for the Reboot Cycle Disabled VA Programming Source Reboot Cycle VA Persistence Behavior Enabling or disabling IO Identity Optimization Normally, after the system boots, the devices are configured and then after a reboot the devices are initialized. You can enable the I/O Identity Optimization feature to achieve boot optimization. If it is enabled, it sets the virtual address, initiator, and storage target attributes after the device is reset and before it is initialized, thus eliminating a second BIOS restart. The device configuration and boot operation occur in a single system start and is optimized for boot time performance. Before enabling I/O identity optimization, make sure that: • 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 cards for IO 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 IO 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 IO 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 auxiliary powered devices and non-auxiliary powered devices. NOTE: The Persistence Policy feature may not work when set to default, if the VirtualAddressManagement attribute is set to FlexAddress mode on iDRAC and if the FlexAddress feature is disabled in CMC. Ensure that you set the VirtualAddressManagement attribute to Console mode in iDRAC or enable the FlexAddress feature in CMC. 174 Inventorying, monitoring, and configuring network devices
