Todd, It means that there were no frames backing this address range.
The normal reason for this is because you have not referenced those frames since the data space was created or you have released the frames backing those data space addresses.

It specifies a particular dataspace token with a single range, starting address of X'00000000' and ending range of X'7FFFFFFF'. The SDUMPX completes normally and I get a dump. Going into IPCS on the dump, and addressing the dataspace, IPCS tells me the range of storage X'00001000' to X'2001FFFF' is not available. Then, it says range X'20020000' through X'200218EF' is all zeros, and then one of my data structures starts at X'200218F0'. However, it's impossible to have a data structure at X'200218F0' without also having an index in the lower address range of the dataspace. That's how my application works (and has worked since 1986). I went to an online storage display program I have and sure enough, the dataspace address X'018236D0' has the pointer to the data structure at X'200218F0', just like it ought to. Where do you reckon the problem lies?
