Could you please let us know if CA-1 v14 is compatible with these new IBM hardware DS8886 and TS7760 VTS?
Release: ONE...00200-14.0-One-TAPE MANAGEMENT
There is no reported issues for CA1 14.0 and any of these products, and neither for DS8886 DASD, or TS7760.
You will need to set the ROBSCR=YES in TMSOPT00 and install the CBRUXENT/EJC (VNL is optional) - but probably it is already done.
With CA1 14.0 please apply the entire maintenance available on our site to prevent any issues.
