Count on those massive disks really working

Yesterday one of the advocates on the OpenMPE board of directors posted a bit of a brag as well as a thank-you to HP. Donna Garverick, who'd lobbied HP along with hundreds of customers voting in the final Systems Improvement Ballot, showed off the results of her first Bigger than 3000 Gig volume under MPE/iX.

Garverick, who manages 3000s for Long's Drug, configured her new disk at 400GB as an interim step, just to check out the programming HP's 3000 lab did to accomodate the bigger disks. Advocates like Garverick and companies who'll have to put several more years onto their 3000s may need to use bigger disks; the HP enhancement lets the 3000 see up to a half-gigabyte of storage.

Before now, an MPE system couldn’t mount a disc drive larger than 300GB. Thanks to Jim Hawkins’ (et al) hard work, we can now. This request was a SIB item from a year ago (or so) and is very much aimed at homesteaders (who at some point won’t be able to find a 4...9...18...gigabyte drive).

Since I’m in the process of bringing up a new system (with a disc array attached), I told HP I could briefly configure this system with a large disc so that I could test their patches.  I built a 400GB LUN — which MPE sees somewhat larger (odd) and viola :-)

I rather figured since I was one of the people advocating for HP to do this work, the least I could do was be decent about it and give it a test drive.

Garverick had started her message to the community by posting a DISCFREE report (under the heading, "i can't count that high" showing so much free space that some people thought she'd erased her volume completely:
