Error description

  • autoconf is one method for configuring devices using the Tivoli
    Storage Manager device driver on Linux.  When autoconf is run
    it deletes /dev/tsmscsi and the device special files within and
    then recreates them.  When autoconf is run with -g or -a it sets
    permissions of device special files to be usable by the
    group (-g) or all users (-a).
      /dev/tsmscsi/lb0
      /dev/tsmscsi/mt0
    It does not explicitly set the permissions of the tsmscsi
    directory:
      /dev/tsmscsi
    In some environments with restrictive umasks, this can lead to
    an error when attempting to open the device.
    ANR8840E Unable to open device /dev/tsmscsi/lb0 with error
    number 13 and PVRRC 2839.
    In this case, the error is not related to the permissions of
    the lb or mt device special file.  The problem occurs because
    the permissions on the /dev/tsmscsi directory are more
    restrictive than the device special files in it.  When autoconf
    is run with -g or -a it should set the permissions of the
    /dev/tsmscsi directory to allow for use of the device special
    files it contains.
    Initial Impact: High
    Tivoli Storage Manager Versions Affected:
      Tivoli Storage Manager 6.3 and higher device driver users
      on Linux
    

Local fix

  • Option 1:
    Manually adjust the permissions of /dev/tsmscsi as desired after
    running autoconf.
    After autoconf -g:
      /bin/chmod g+rwx /dev/tsmscsi
    After autoconf -a:
      /bin/chmod a+rwx /dev/tsmscsi
    Option 2:
    Change the umask of the user running autoconf to allow for the
    desired access.
