One thing to be careful when you read "unsupported". Many times it just means that it isn't configurable via the IUI interface. I run some 3380-3 drives, many 3390-3, some 3390-9 and a few 3390-27 packs. But I only have 3390-3 packs as the max size for VSE. (I just don't have a real reason for having large packs for VSE.)
Our DS6800, under z/VM 5.1 is running our: (5) VSE/ESA 2.3.2 systems (2) VSE/ESA 2.5.1 systems (2) VSE/ESA 2.7.2 systems 23 Linux systems from Suse 7.3, Suse 8.0, Suse 9.0 (31 and 64 bit systems) But they are all minidisks. I do run flashcopy, but I have only done the flashes from VM. Tom Duerbusch THD Consulting On Friday 31 March 2006 15:33, Steve Wilkins wrote: > Unfortunately, there isn't any fine print.
