Saving storage (Licensed Internal Code data and disk unit data)

 

There are important factors to remember when saving Licensed Internal Code data and disk unit data.

The save storage process copies the Licensed Internal Code and all of the disk unit data to tape. The media volume that the system produces is a sector-by-sector copy of all permanent data on configured disk units. You cannot restore individual objects from the save tape.

You should use the save and restore storage processes for disaster backup and recovery along with the standard commands for saving and restoring. This procedure is not intended to be used for copying or distributing data to other systems. IBM^® does not support using the processes for saving and restoring storage as a means to distribute the Licensed Internal Code and the operating system to other system.

• Operational considerations for saving storage
  Before you save storage, take the information in this topic into consideration.

• Recovering from save storage errors
  If a tape error occurs, the system attempts to recover from the error by automatically trying the operation again.

• Saving storage for mirrored protection
  If the system is using mirrored protection, only one copy of the data from each mirrored pair is saved. When you restore your system by using the SAVSTG tapes, mirrored protection will not be active.

• Canceling a save storage operation
  To cancel the save storage operation, press the F19 key. This action cancels an active save storage operation.

• Resuming a save storage operation
  There are certain requisites that your system must meet before you can resume a save storage operation.
