If you want to replace the NIC with another card of same model, you must initially run the
olrad(1M) command with -C option which reports the resource usage and its criticality.
In this example, as the FLA NIC is having IP configured, the criticality reported by CRA in this case
will be CRA_DATA_CRITICAL and for more information about the CRA details, see the CRA log
file /var/adm/cra.log on the VSP. The following is the snippet from the CRA log on the VSP
containing the HPVM Direct I/O Analysis details.
ANALYSIS SCOPE: HPVM- DIRECT I/O
This report provides details of any critical Direct I/O hardware path usages in the system.
RESULT: DATA CRITICAL Direct I/O resources will be affected.
SYSTEM CRITICAL RESULTS
Affected vPars or VM guest instances numbers are: NONE
DATA CRITICAL RESULTS
Affected vPars or VM guest instances numbers are: 1 3
WARNING
Affected vPars or VM guest instances numbers are: NONE
FAILURE
Vpars or VM guests that failed to perform CRA analysis are: NONE
The CRA that logs inside the guest have additional information about the DATA critical usage
inside the guests.
In this scenario, where the CRA has returned DATA CRITICAL, if you choose to run the Pre
Replace option of the olrad (1M) command (olrad –r option), as in example 1, the operation
fails with CRA_DATA_CRITICAL error, reason being that doing this operation renders each of the
VM guests (Guest 1 and Guest 3) VM where the FLA NIC ports are assigned, inaccessible to
network.
As in example 1, if you want to override the CRA criticality report, you can do so on your own
risk by using the force (–f) option of the olrad command. The olrad(1M) and ioscan(1M)
commands can be used to verify that the FLA NIC is successfully suspended.
Further, ioscan output inside each of the guest (Guest 1 and Guest 3) will also show the
corresponding FLA NIC port in SUSPENDED state.

After the FLA NIC is replaced with a new one, the Post Replace option of the olrad(1M)
command (olrad –R) can be used to resume usage of the card. The olrad(1M) and ioscan
commands can be used to verify that the FLA NIC is successfully resumed.
