Which two utilities can be used to predict the consequences of a filesystem failure for the Oracle 12c Clusterware stack?
A.
asmcmd
B.
srvctl predict….
C.
crsctl fail….
D.
asmca
E.
acfsutil
F.
advmutil
Explanation:
B: The srvctl predict filesystem command predicts the consequences of file system failure.
E: The acfsutil info fs command displays detailed Oracle ACFS file system information, such as:
iscorrupt – 1 if the file system is corrupt, 0 if file system is not corrupt.
Incorrect Answers:
A: ASMCMD is a command-line utility that you can use to manage Oracle ASM instances, disk groups, file access control for disk groups, files and directories
within disk groups, templates for disk groups, and volumes.
C: There is no crsctl fail command.
There is a crsctl eval fail resource command to predict the consequences of a resource, not the file system, failing.
D: Oracle ASM Configuration Assistant (ASMCA) supports installing and configuring Oracle ASM instances, disk groups, volumes, and Oracle Automatic Storage
Management Cluster File System (Oracle ACFS). In addition, you can use the ASMCA command-line interface as a non-GUI utility.
F: advmutil canonical displays the canonical name of the specified Oracle ADVM device name.
dvmutil tune displays the value of a specific Oracle ADVM parameter or sets the value of a specific Oracle ADVM parameter.
advmutil volinfo displays information about Oracle ADVM volume devices.

B,E CORRECT
The srvctl predict command allows administrators to evaluate the consequences of a
failure.
You can view the file system information including the number of snapshots with:
acfsutil info fs /u01/app/oracle/acfsdata/testvol
It should be B & C:
srvctl predict filesystem: Predicts the consequences of file system failure
crsctl eval fail resource ora.diskgroup.volume.acfs: Predicts the consequences of an Oracle ACFS file system resource failing
What we have as a choice is crsctl fail …. not crsctl eval fail
“B”, “C” and in the exam they ask for a third option that i don’t remember!
BE is the correct answer, there is no command like crsctl fail..
B and C on the presumption that in the exam it will be listed as crsctl eval fail
I can’t see that E is right as the question says a tool that can PREDICT the consequences of a failure. acfsutil info fs may be able to tell you if the file system is corrupt, but this is different than predicting.
B and C are the correct answers.
crsctl eval fail resource: Predicts the consequences of a failure of a resource.
