Why not?  ;-)

Realize that you're asking us, when we have no context for the
failure condition or operating environment.
What operating system is it?  If it's Unix, the error 2 would likely
be an ENOENT errno, as in no device there, as addressed.
Presumably, you've performed the basic diagnostic steps that would be
done at the operating system level to test for whether the hardware
is intact (as in cabling) and operating (is everything turned on?)
and responding...  What did you find at that level?  Does the library
respond to its Web page or SNMP or similar probes?  Any errors in the
operating system error log?  Was any work performed by operators or
vendors (as in repairing or replacing a key drive)?  Did your
operating system people make any configuration changes?  Were there
any site power problems which may have damaged equipment?
