It?s been a while, so I thought I?d update folks on what?s been going on with my IBM
Multiprise 3000 S/390 mainframe. I?ve updated the webpage for it at:
http://www.shiresoft.com/new-shop/Shiresoft/IBM_Mainframe.html#grid
<http://www.shiresoft.com/new-shop/Shiresoft/IBM_Mainframe.html#grid> to indicate
it?s current status.
I?ve managed to boot it up into the version of z/OS (V1R5) that was installed. I
discovered that some of the standard users were still present with their default passwords
so I was able to log in and do stuff under TSO. I also figured out that one of the
standard users had administrative capabilities, so I?m able to fully manage z/OS and make
the changes necessary to have it work in my environment and to be able to perform any
administrative tasks that I might need to perform.
I?ve configured the OS/2 side of things to be on my home network, so I can at lead use one
of the various tn3270 programs to log in rather than having to sit as the OS/2 screen and
do things. I also reconfigured my 3174 controller so that it could ?talk? to the MP3000
so I can also use my 3179 terminals to log in (which IMHO are much better than the tn3270
programs).
During all of this I acquired 8 more 18GB SSA drives so I have enough for a second 72GB
array with some spares. I felt really fortunate to have found these drives as they are in
no way standard (524 byte sectors) and you need the special carriers to work properly in
the MP3000. Not to mention that they are SSA drives!
I have put the drives into the MP3000 but have yet to configure them for use. During the
checkout of the drives, I discovered that the drive that had been assigned for the ?hot
spare? was dead. One of my next tasks will be to assign one of the new drives as the ?hot
spare?.
Since I have most things working now, I moved the MP3000 into a more convenient location
in my office (see picture on the above link) rather than being in the middle of the
traffic area of my shop.
I?m still going to be doing some ?tinkering? with z/OS before I really knuckle down to
(re)learn the various aspects of MVS and TSO. Then off to write some mainframe programs!
