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.
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.
