Re: Definition of z/OS SYSRES volume

[Seymour J Metz]

The sysres volume is the volume containing SYS1.NUCLEUS and that you IPL from .

I'm not sure whether it would be confusing or helpful to draw analogies with 
specific Linux directories, e.g., /bin, /sbin.

There are other important volumes needed in the IPL process, e.g., IODF, master 
catalog, parmlib.

Fair, I thought you were looking for a way to explain in an educational context 
rather than a precise definition.  I find that in introducing new people to Z 
its better to relate to known ideas and progressively explore the details.

Re: Definition of z/OS SYSRES volume

[Michael Watkins]

Perhaps 'z/OS system installation and maintenance', P.9, is sufficient:

"The z/OS software- as supplied by IBM- is usually installed on a series of 
disk volumes known as the system residence volumes (SYSRES). Much of the 
flexibility of z/OS is built on these SYSRES sets. They make it possible to 
apply maintenance to a new set that is cloned from the production set while the 
current set is running production work. A short outage can then be taken to IPL 
from the new set--and the maintenance has been implemented! Also, the change 
can be backed out by IPLing from the old set."

Re: Definition of z/OS SYSRES volume

[Charles Mills]

Pretty easy if you ask me. The volume from which the operating system was
loaded. (Or at least the key part of the operating system, the nucleus and
such.)

SYSRES = System Residence volume, the volume on which the [operating] system
resides.

Re: Definition of z/OS SYSRES volume

[Rahim Azizarab]

SYSRES generally refers to the IPL Volume, so it maybe fair to assume that you 
are asking how to create a rescue volume, or an ipl-able DASD.  There are some 
examples for OS390 on cbttapes.org in File 164, but I was able to only get the 
new volume ipl and start JES2.  I have not been able to get the VTAM 
functioning on the new DASD. There is already a Rescue volume on Zos.
