Version 8 of the Equallogic PS firmware introduces a default policy for automatic snapshot creation. This means that by default, a daily snapshot will be created for each volume present in the group. The policy also states to keep 2 snapshots, which can be very space consuming, quickly filling up your Equallogic.

When upgrading the firmware to version 8 from an earlier version, this policy will automatically be created and activated, without telling you, causing headaches among those unaware of this change.

From the CLI, you can check whether the default policy is active:

grpparams default-snapshot-sched show

To turn off this policy from the CLI, type this:

grpparams default-snapshot-sched disable
