In order for JES2 to actually use a big volume, you have to change SPOOLDEF
to LARGEDS=ALLOWED. Also, all MAS members must at a minimum release level:
I believe it's 1.7. Furthermore, once the large spool is in use, no member
can fall back to a pre-minimum level. You might also need to increase
TGSPACE in order to allocate the whole volume. All of these changes are
dynamic but should be 'backed up' in the init deck.
Having said all this, large spool volumes work great. No performance
problems at all.

Use this JCL to allocate all of a 3390-9, or 99% of it.

Subject: Allocating Large SYS1.HASPACE
Hi,
I'm beginning to play with large (>64K tracks) JES2 spool datasets. I'm
attempting to allocate one entire 3390-9 volume (150239 tracks or 10015+
cylinders).
