Regarding getting information about a disk...
Rather than issuing a DIAG x'08' and parsing the output, I'd suggest
you look at DIAG x'24' (DEVTYPE) and (under XA SP 2.1 at least) DIAG x'210'
which returns device-specific features...
For the terminally ambitious, there's also the appropriate CCW commands
for 'Read Device Characteristics'... but this isn't for the faint-hearted.
