Users Guide

NOTE: When a persistent policy is disabled and when you perform the action to lose the virtual address, re-enabling the
persistent policy does not retrieve the virtual address. You must set the virtual address again after you enable the persistent
policy.
NOTE: If there is a persistence policy in effect and the virtual addresses, initiator, or storage targets are set on a
CNA-device partition, do not reset or clear the values configured for virtual addresses, initiator, and storage targets before
changing the VirtualizationMode or the personality of the partition. The action is performed automatically when you disable
the persistence policy. You can also use a configuration job to explicitly set the virtual address attributes to 0s and the
initiator and storage targets values as defined in iSCSI initiator and storage target default values on page 188.
Configuring persistence policy settings using iDRAC web interface
To configure the persistence policy:
1. In the iDRAC Web interface, go to Configuration > System Settings > I/O Identity Optimization.
2. Click I/O Identity Optimization tab.
3. In the Persistence Policy section, select one or more of the following for each persistence policy:
● Warm Reset - The virtual address or target settings persist when warm reset condition occurs.
● Cold Reset - The virtual address or target settings persist when cold reset conditions occur.
● AC Power Loss - The virtual address or target settings persist when AC power loss conditions occur.
4. Click Apply.
The persistence policies are configured.
Configuring persistence policy settings using RACADM
To set persistence policy, use the following racadm object with the set sub command:
● For virtual addresses, use iDRAC.IOIDOpt.VirtualAddressPersistencePolicyAuxPwrd and
iDRAC.IOIDOpt.VirtualAddressPersistencePolicyNonAuxPwrd objects
● For initiator, use iDRAC.IOIDOPT.InitiatorPersistencePolicy object
● For storage targets, use iDRAC.IOIDOpt.StorageTargetPersistencePolicy object
For more information, see the iDRAC RACADM CLI Guide available at https://www.dell.com/idracmanuals.
iSCSI initiator and storage target default values
The following tables provide the list of default values for iSCSI initiator and storage targets when the persistence policies are
cleared.
