Chris,

The text below is from the V5R2 Backup and Recovery Guide.  Disk
protection will not be started by a RSTSTG operation.  The text
regarding parity protection is not in the V5R1 manual (nor is it flagged
with the vertical stripes indicating new text in the V5R2 manual) but I
assume that this is not new.

Because starting RAID on new drives could result in some disks having
less actual storage capacity than the previous configuration, this
raises some intriguing questions for your circumstances.

Al, had you turned off RAID on your configuration or were you performing
your RSTSTG over a live system with disk protection active?

Regards,
Andy Nolen-Parkhouse

The disk configuration of the restoring system must be the same as the
disk configuration of the saving system. There must be at least as many
disk units on the restoring system as there were on the saving system.
Each disk unit capacity on the restoring system must be equal to or
greater than the capacity of the disk unit on the saving system. Serial
numbers and physical addresses do not have to be the same. All disk
units that were saved are required for the restore operation.

The restore storage process does not automatically start or stop device
parity protection on the restoring system. If you determine that the
disk units on the restoring system should be protected with device
parity protection, start device parity protection before restoring the
SAVSTG tapes.

If your system has mirrored protection now, when the restore storage
procedure runs, your system will not have mirrored protection on any
Auxiliary Storage Pool (ASP).
