You're administering a 10GB volume on a test server that regularly receives new builds that replace most or all of its contents. The build currently under test has an issue that is in the process of being resolved, when a critical production issue arises. Within an hour, the test build you're working with will be overwritten by a copy of the production build, and your working volume under test will be overwritten by a copy of the production build, for its problem resolution. Given that you don't have time to synchronize a snapshot of your test build before it gets overwritten, what technique can you use to get a snapshot of the test volume ready to preserve the state of your test before testing gets set back a week by being overwritten by the production copy?


Options are :

  • Use vxsnap addmir to create a snapshot mirror on the test volume, then use vxsnap make with the nmirror=1 option to convert the mirror into a snapshot volume.
  • Use the vxsnap make command with the cachesize=1g option.
  • Use vxassist to create an empty volume matching the size of the test volume, then use vxsnap make with the snapvol option and the sync=off option to attach the new volume to the test volume as a snapshot.
  • Use the vxsnap make command with the plex option to convert an existing plex of the test volume into a snapshot.

Answer : Use vxassist to create an empty volume matching the size of the test volume, then use vxsnap make with the snapvol option and the sync=off option to attach the new volume to the test volume as a snapshot.

You are monitoring I/O on a volume that is under Veritas Volume Manager control using the vxstat command. You need to measure the impact of a specific write operation on a volume. You want to ensure you are successfully able to measure the impact. What should you do?


Options are :

  • Reset the statistics information to zero just prior to the specific write operation
  • Reset the statistics information to zero just after the specific write operation
  • Reset the statistics information to zero during the specific write operation
  • Reset the statistics to measure the impact of all write operation, not a specific write operation

Answer : Reset the statistics information to zero just prior to the specific write operation

You execute the vxtrace command without any option to collect I/O trace data on all virtual disk drives during peak I/O operations. When you start to analyze the data, you notice that vxtrace displays a record indicating records are lost. You want to reduce the likelihood of the kernel discarding records so that you do not have to rerun vxtrace to capture the records. What should you do?


Options are :

  • Increase the kernel buffer using the -o option
  • Wait until I/O operations have decreased
  • Increase the kernel buffer
  • Print vxtrace event records to a file

Answer : Increase the kernel buffer

You have a customer who has set up a 5 GB full-size instant snapshot volume on one of his file servers. The data replicated into the snapshot is a combination of code and content elements, which serves as a rapid recovery mechanism in case of a corruption in a new build installed on the server. The customer tells you that the snapshot is working correctly, but that the time it takes to refresh the snapshot is unusually longer than expected. The customer is expecting you to resolve this problem. How should you resolve this problem?


Options are :

  • Use vxassist addlog logtype=dco to enable FastResync on the volume
  • Use vxsnap prepare on the source volume, then remove and recreate the snapshot
  • Recreate the snapshot as a traditional third-mirror break-off snapshot
  • Recreate the snapshot as a space-optimized instant snapshot

Answer : Use vxsnap prepare on the source volume, then remove and recreate the snapshot
