Prepare for recovery of a head crash on an ML1 volume

To prepare for recovery of a head crash on an ML1 volume, perform the following steps:

1. Use the IDCAMS EXPORT TEMPORARY command to regularly export SDSPs with high activity.
   Note: Be sure to use the TEMPORARY parameter with the EXPORT command so the export function does not delete your original data set.
2. Dump ML1 volumes regularly.
