Yes, it's ready for Linux use as a swap device. You just need an entry for "swap" in the /etc/fstab file....... DJ

So this swapgen utility makes the V-Disk linux ready? Does that mean it's formatted as swap? What do you do then within in the Linux guest to use the device as swap?

Version 5 of SWAPGEN is now available from http://www.sinenomine.net/downloads
It's pretty much the same as version 4, but there's a new option: REUSE
If your system policy doesn't allow your guests to define their own VDISKs, but instead mandates that they be present in the directory entry, you can use, for example,
SWAPGEN 152 200000 ( REUSE
(which would write a Linux swap signature on a DIAG-accessible, CMS-FORMATted and RESERVEd 200000 block V-DISK at address 152).
Note that if you're using REUSE you still have to specify the size in 512-blocks, and it needs to match the actual device size. I agonized over putting the feature in at all, because it makes it possible to destroy extant data with SWAPGEN (which was not previously possible), and I finally compromised by only touching devices whose size you've specified on the command line. Consider that the safety catch: if you've said REUSE and you know the size of the device, we assume you really do mean to overwrite it.
REUSE is *not* the default. The default is still to detach whatever's at the address you specify, allocate a V-DISK at that address, and use it.
