Sorry... I didnot get you completely... Are you saying... say I request Primary Quantity as 100 Cyls , there was not enough space in any volume (STORAGE Group) which could allocate 100 Cyls in Single Extent?
Please let me know if this understanding is correct. In such cases how do I make sure it spans in 1 Extent?
Yes, I do not remember the exact sequence for the choice of eligible volumes
1) search for a volume with the total space requested available
2) search for a volume with the total space requested available in a single extent
at a certain point as many extents needed will be allocated
if <requested> and no contiguous space is available You will get IIRC a jcl error
are You defining the CLUSTER or are You letting DB2 do it under the covers ?
