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 on page 177 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
