snap -e

Edit online

For PowerHA® SystemMirror®, the AIX® snap command includes an -e flag which will gather all the necessary PowerHA SystemMirror data. In an PowerHA SystemMirror cluster, it will try to gather data from all defined nodes, whether the cluster is up or down. See the AIX Commands Reference for more information about the snap command and the -e flag in particular.

Basic information about the snap -e command:
  • Used for: PowerHA SystemMirror clusters
  • Full path name: /usr/sbin/snap -e
  • Default output location: /tmp/ibmsupt/
Output is a compressed pax file (snap.pax), which contains the elements gathered in /tmp/ibmsupt/hacmp/.
Notes:
  1. The snap -e command does not collect data about the RMC subsystem, which it uses instead of emsvcs starting in PowerHA SystemMirror 5.2. If an RMC problem is suspected, you should run ctsnap separately (see the previous explanation in ctsnap).
  2. The snap -e command uses the phoenix.snap tool as part of its data collection process. So, if you have difficulty getting the snap -e command to complete successfully, you can also run phoenix.snap on any node in the cluster to ensure complete RSCT data collection.
