I just had this same error on a AIX 5.1 using a 3494 tape lib with 3590E 
drives. 

we found that the only solution that worked was to delete and redefine the 
device description in the AIX environment. you can also try cycling your 
server.

We have a shared 3584 LTO library.  We are getting the following errors:

Was logged as a hardware problem but may need to open it up as a TSM problem.  
No errors show up with "errpt -a" on the AIX server.

12/11/03 13:13:36     ANR8779E Unable to open drive /dev/rmt3, error number=6.
12/11/03 13:20:41     ANR8779E Unable to open drive /dev/rmt5, error number=6.

ANR8779E

Explanation - The drive cannot be opened by the server.  In AIX, error number 
is the value of errno returned by the operating system.

System Action - The transaction needing the drive fails.

User Response - User error number in conjunction with operating system 
documentation to narrow the scope of the cause.  Inspect the drive.  Ensure the 
dirve is powered on and ready, the cables are properly connected and terminated 
and that the device is properly configured to the operating system.

----

The drives have been cleaned, power cycled, etc.

Has anyone seen this or have any ideas?
