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.
NOTE: IO identity and configuring of IO identity persistence policy is not supported on PCIe devices
available in the Dell PowerEdge FX2/FX2s chassis.
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.
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.
