Users Guide

NOTE:
● This attribute is persistent over iDRAC reboot.
● Firmware reset to default will disable this feature.
● While Serial Data capture is enabled, the buffer keeps getting appended with recent data. If user disables Serial capture
and enables it again, iDRAC starts appending from last update.
The System serial data capture starts when user enables the serial data capture flag from any of the interfaces. If serial data
capture is enabled after the system has booted, you have to reboot the system, so BIOS can see the new setting (console
redirection Enabled requested by iDRAC) to get the serial data. iDRAC will start the data capture continuously and stores to the
shared memory with limit of 512 KB. This buffer will be circular.
NOTE:
● For this feature to be functional, one must have Login privilege and System control privilege.
● This feature requires iDARC Datacenter license.
Dynamic configuration of virtual addresses, initiator,
and storage target settings
You can dynamically view and configure the virtual address, initiator and storage target settings, and apply a persistence policy.
It allows the application to apply the settings based on power state changes (that is, operating system restart, warm reset,
cold reset, or AC cycle) and also based on persistence policy setting for that power state. This provides more flexibility in
deployments that need rapid re-configuration of system workloads to another system.
The virtual addresses are:
● Virtual MAC Address
● Virtual iSCSI MAC Address
● Virtual FIP MAC Address
● Virtual WWN
● Virtual WWPN
NOTE:
When you clear the persistence policy, all the virtual addresses are reset to the default permanent address set at
the factory.
NOTE: Some cards with the virtual FIP, virtual WWN, and virtual WWPN MAC attributes, the virtual WWN and virtual
WWPN MAC attributes are automatically configured when you configure virtual FIP.
Using the IO Identity feature, you can:
● View and configure the virtual addresses for network and fibre channel devices (for example, NIC, CNA, FC HBA).
● Configure the initiator (for iSCSI and FCoE) and storage target settings (for iSCSI, FCoE, and FC).
● Specify persistence or clearance of the configured values over a system AC power loss, cold, and warm system resets.
The values configured for virtual addresses, initiator and storage targets may change based on the way the main power is
handled during system reset and whether the NIC, CNA, or FC HBA device has auxiliary power. The persistence of IO identity
settings can be achieved based on the policy setting made using iDRAC.
Only if the I/O identity feature is enabled, the persistence policies take effect. Each time the system resets or powers on, the
values are persisted or cleared based on the policy settings.
NOTE: After the values are cleared, you cannot re-apply the values before running the configuration job.
