These jobs created three awstape files (emulated tape volumes) on the initial z/OS system.
We then compressed the large file containing the dump, using the command:
$ gzip -c /tapes/DUMP01 > DUMP01.gz
Finally, we used a standard program to burn the three files (containing the two small
standalone programs and the compressed DUMP01 file) to a CD. We then took the CD to the
1090 machine. (A CD is not really required, of course. We could simply FTP the files to Linux
on the 1090 machine if a suitable network is available.) The CD burning program we used
created a CD title of “CDROM.”
We also noted that the one-volume z/OS system recognizes a suitable 3390 address (device
number) for the system residence as A8F, expects to find a z/OS console at address 700, and
can use a local 3270 TSO terminal at address 701.
Linux directories
We used the following arrangement on the 1090 machine:
򐂰 Our userid was ibmsys1; it was a member of group ibmsys.
򐂰 Our home directory was /home/ibmsys1.
򐂰 Directory /z was created to hold System z emulated disks and tapes. It is a separate file
system (partition) that was created when Linux was installed and has ample free space.
Read the CD
We copied the standalone programs from the CD and uncompressed the dump tape:
$ cd /z
$ ls /media/CDROM (verify CD is readable)
$ cp /media/CDROM/SAINIT /z/SAINIT (DASDI program)
$ cp /media/CDROM/SAREST /z/SARESTOR (restore program)
$ gunzip -c /media/CDROM/TAPE01 > /z/TAPE01 (dump tape)
$ ls -al (verify files are on disk)
SAINIT 1108042 bytes
SARESTOR 232648 bytes
TAPE01 956763522 bytes
(you may close the CD window and remove the CD)
Create 1090 files
We created the new emulated disk volume on the 1090 system:
$ alcckd /z/SARES1 -d3390-3 (resulting volume 2.8 GB)
We created and checked /ibmsys1/aprofi.txt for the devmap:
$ cd /home/ibmsys1
$ gedit aprofi.txt (or use your favorite text editor)
