John,
You are right. MPE/iX will automatically balance the data among your
disk drives, based on the amount of free space. The trick of
manipulating the membership of the DISC device class is from classic
days, and no longer applies in the RISC environment.
Regards,
John Clogg

Subject: Re: ldev lists in classes - DISC
Tried
Mdev 2 class=disc,disc,disc
No error, but no change either..
Ldev 1 is 18gb, ldev 2 is 36gb.
Maybe they are self balancing, as ldev 1 has 21m sectors free, vs ldev 2
with 46m sectors, close to 1:2.
Maybe I should stop worrying about it.
Thanks for the inputs.
jp
disc,disc for ldev 2
disc for ldev1
