Error description

  • The Tivoli Storage Manager server dismount of a volume can
    report the following reservation conflict message:
    
    ANR8311E An I/O error occurred while accessing drive xxx for
    PREEMPTABORT operation, errno = 16, rc = 1
    
    The volume will be dismounted with success afterwards.
    
    This problem is limited using the Atape driver.
    
    There is a mismatch in a key exchange between the Tivoli Storage
    Manager server and the Atape driver. The server did not set this
    key to the ADSM_DDIOC_PREEMP_ABORT ioctl.
    
    Customer/L2 Diagnostics:

    backup. The reservation conflict occurred after the dismount
