Okay, I'm pretty sure I know the answer to that, but stupid and me sit next to each other fairly often... :-)
Anyway, we're in the midst of refreshing our DASD and part of that will be to get rid of MOD3s. This happens to be what we use for secondary swap on each Linux guest so a little rethinking is in order. (We use DCSS for primary swap.) The boring alternative would be to do a one for one swap of a MOD9 for a MOD3. Or define a pool of MOD9s and dole out a MOD3s worth using DIRMAINT. But, I like a little excitement every so often, so I got this crazy idea to replace all secondary swap with VDISK and just boost up the VM paging volumes. We don't actually hit Linux swap all that much so probably 15% or so of that 275GB is ever really in use. (Yes, I know...we're probably oversizing our guests, but that's a different story.) I know I'd have go boost up the number of paging volumes, but does VM have to map all of that storage even if it doesn't get used? So what do y'all think? Have I been drinking too much of Adam's cough syrup? Leland
