Snapshots of Unix/Linux Filesystems are Being Seen by the cdm probe(CA UIM)

When creating snapshots of a Unix/Linux filesystem for backup, the cdm probe will see the snapshot as another mount.


Most Unix and Linux operating systems have a built-in method to assist system backups by using filesystem snapshots.

A snapshot starts with freezing the filesystem, then (particularly in Linux) creating a logical volume and mounting the filesystem image to it.  This is then accessible to the backup utility.  When backup is complete, the snapshot is unmounted and destroyed.


If you don't want the snapshot to be part of your cdm monitoring, you can use the Ignore Filesystem option within the probe.

The value should be a regular expression that would match all disks and/or file systems you want the probe to ignore. Here is an example how to ignore Auto-mounted disks that are recognized on each "disk interval":
