That assumes you have access to the HMC in the first place. I don't know what his environment is like, but I'm 1000 miles away from the data center, and in any case, they don't allow anyone NEAR the HMC during business hours.
Setting up VM initially might take a little longer (like one day if you know what you're doing), but the benefits come back quickly. The one thing I did forget to mention before is that if you're going to set up an LPAR, it helps to carve out a subset of DASD defined only to that LPAR, and try to standardize the addresses. When you're dealing with real addresses, you can't move them around as easily as you can with virtual minidisks, and Linux will scan ALL available DASD devices on IPL. -----Original Message----- From: Linux on 390 Port [mailto:[email protected]] On Behalf Of David Andrews Sent: Friday, March 13, 2009 12:01 PM To: [email protected] Subject: Re: [LINUX-390] starting 'at the begining' to install linux on z/os On Fri, 2009-03-13 at 11:23 -0400, Hall, Ken (GTS) wrote: > The installation on bare metal is tricky (as those of us who have > installed under Hercules have found) and requires access to the HMC for > possibly many sessions to get things right so it will come up and > install. Installing Debian from the HMC cupholder was pretty easy; I got it done in an afternoon. What's more time-consuming is getting the LPAR defined, with the DASD device addresses properly isolated from your production system(s). Took me several iterations with HCD to get it right, and much longer than it took to install Debian itself. (HCD and I don't get along all that well.) There might be some downtime associated with creating a new LPAR, depending on your dynamic-reconfiguration-fu and whether you've got spare memory to carve out. I'm not VM-literate, so it took me less time to build the LPAR than it would have taken me to install and learn VM. (Not to mention that I'd have had to convince someone to pay for it.) DB has a litany of reasons for using z/VM in your Linux farm, and you should generally listen to anything he says... but for my modest purposes a single little LPAR works just fine. -- David Andrews A.
