HP-UX vPars and Integrity VM V6.3 Administrator Guide

Critical Resource Analysis(CRA) in progress...
[NOTE: The CRA may take a few minutes to complete on large
configurations. It is recommended not to disrupt this operation.]
CRA REPORT SUMMARY: CRA detected DATA CRITICAL usages.
Detailed CRA report is available in /var/adm/cra.log file.
The criticality reported by CRA in this case is CRA_DATA_CRITICAL and for more information about
the CRA, 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: 5
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 guest. The following is a snippet from the CRA log in the guest for this specific scenario.
ANALYSIS SCOPE: NETWORKING
This report provides details of any networking related usages for
a set of h/w paths in the system.
RESULT: DATA-CRITICAL resource usage detected.
DETAILED REPORT: Analyzed following hardware paths to detect any
usages in the system:
0/1/5/0 (lan8)
0/2/2/0 (lan17)
DATA CRITICAL RESULTS:
Interface lan8: IPv4 address 15.213.156.42
Interface lan17: IPv4 address 15.213.156.43
USEFUL NETWORKING COMMANDS:
lanadmin lanscan nwmgr netstat ifconfig linkloop
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), the operation fails with
CRA_DATA_CRITICAL error, reason being that doing this operation renders the VM guest where
the DLA NIC ports are assigned, inaccessible to network.
However, 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. If any of these operations must be performed
for system administration purposes, then you must re-assign all the IP addresses configured on each
of the ports of the NIC to be replaced to alternative NIC cards.
The following is the sample output of the olrad(1M) command when run with the force (-f)
option:
