QDISK is an enhancment to and quadri-modal repackaging of XASTOR, QDISK,
DLIST and QDEVS (available separately).
It was devised and constructed by Kris Buelens formely IBM Belgium. Contents include updated versions of DLIST, QDISK (part of the DLIST package), and QDEVS, as well a QACCESSD, a tool modelled on QDISK. See the QDISK PACKAGE file for more details.
Enhancement means that improvements were applied to the
original version of QDISK and DLIST. Like recognizing that RACFVM
is also using CMS.
Repackaged means that the same vesion of the execs can run on different level of the z/VM family, from VM/ESA, up to z/VM V7. The execs will load an apropriate version of XASTOR to make it work.
The REXX execs all display devices or accessed disks of other virtual machines, so are meant for VM system programmers. You must have the privilege class(es) required for the CP LOCATE command and Diagnose x'04'.
- Displays devices a virtual machine currently has defined to it.
- Displays disks/SFS dirs ACCESSed by a CMS or GCS user. Like Q DISK thus.
- Displays disks/SFS dirs ACCESSed by a CMS or GCS user, like Q ACCESSED.
- Displays a fullscreen list of disks used by a CMS or GCS user.
These tools are invaluable when exploring a system with many SVM's that one is not too familiar with. You can easily see which MDISKs are LINKed, what is ACCESSed, and with DLIST looking on a disk ACCESSed by an SVM is simply PF11. Here the screen resulting from DLIST DIRMAINT
