Chapter 4. IXFP/SnapShot for VSE/ESA
IXFP/SnapShot for VSE/ESA is a combination of software and RVA microcode
functions. It has three main functions, namely, SnapShot, DDSR, and Report.
SnapShot is the data duplication utility that exploits the RVA′s virtual disk
architecture to achieve instantaneous copy without actually using resources.
DDSR releases space occupied by a volume, a cylinder range, and a specified
data set. The report functions provide information about the space utilization
and subsystem utilization summary of the RVA.
A new attention routine ($IJBIXFP) has been provided in VSE. You invoke
IXFP/SnapShot for VSE/ESA functions through the attention routine in three basic
ways:
1. From a console
You enter the IXFP/SnapShot for VSE/ESA functions on the command line of
the VSE operator console or through the interactive computing and control
facility (ICCF) console operator interface.
Note: Make sure that you are authorized to enter operator commands when
using the ICCF console operator interface.
Figure 6 illustrates invoking IXFP REPORT functions directly from the
operator console.
