While VMDUMP is handy because it is "always there" under VM, it is so darn slow that it makes its use really unacceptable for large virtual machines (more than 2 hours to dump an 8G virtual machine). Even for a small Linux system of 800M, it's 22 minutes (and that's with a very robust DASD subsystem, not old junk ;)
Fortunately, making one with "zipl -d" works well and is fast (3 minutes for 8G - what the heck is vmdump doing for 2 hours !!??!!) My question is can a dump volume created with "zipl -d"from s390-tools 1.5.6 on sles9 be used to dump a sles 10 (s390-tools 1.6.3) system? i.e. can I get away with just one? Or do I need one for each? Or if I can't use the sles 9 one on sles 10, can I use a sles 10 created one for sles 9 ?
