Additionally, he said that he *had* been planning to use the same volser for both systems SPOOL volumes. SAPL's "DEVICE NUMBER:" field will let you point to a specific device address for the IPL volume, but the first matching SPOOL volser(s) would be found. If that was from the system without the maintenance, the wrong SDFs would be used. Your gun, your foot.
Duplicate volsers are simply an invitation to self-imposed disaster. They can be used if you are _both_ experienced ... and LUCKY! But it is _your_ _job_ on the line! Why expose yourself to potential problems when there are other, perfectly reliable, means to avoid problems? Mike Walter Aon Hewitt The opinions expressed herein are mine alone, not my employer's.

What happens if one of the devices at the lower address fails to respond to the IPL roll call? That is a case of having only 1 device, the wrong one, with the volser.
