Question :-

What must be considered when a host has XtremSW Cache installed and SRDF functionality is required for its volumes?
SRDF operations that will cause data to be copied to an actively cached device will be blocked unless a special command flag is used.
XtremSW Cache has no impact on SRDF since XtremSW Cache is host based and SRDF is Symmetrix based.
XtremSW Cache and SRDF are mutually exclusive due to the potential for writes remaining in XtremSW Cache instead of being written to the R1
SRDF operations that will cause data to be copied to an actively cached R1 device will be blocked unless a special command flag is used, but actively cached R2 devices are not affected.
