查块错误，结果发现在Linux的日志/var/log/message里面看到下面错误信息：
Feb 23 23:26:10 oadata SYMBDSNAP_SDK[5251]: Failed to open device: /dev/symbdsnapctl, errno: 2.
Google搜索了一下，发现出现这个错误的原因，以为是硬件错误，结果不是：
Advanced Open File Option for Linux (AOFO-L) is not supported for the use with the kernel version. (For details, please see NOTE below.)
NOTE:
"SymBDSnap" in messages is a driver name for AOFO-L.
The requisite to enable AOFO-L depends on the kernel versions rather than Linux OS versions.
Please refer to the following URL for the kernel version corresponding for each Red Hat release version, since the available kernel versions are not described in Software Compatibility List (SCL) for Backup Exec.
Software Compatibility List (SCL) for Backup Exec 2012 says that AOFO-L is supported for the use with Red Hat 6 Update 1. Red Hat says that the kernel version for Red Hat 6 Update 1 is 2.6.32-131.0.15.
AOFO-L is supported for the use with 2.6.32-131.0.15 as a consequence. If the kernel version is 2.6.32-220 or later, AOFO-L is not supported as of 12 August 2013.
刚好出现错误的系版本为Oracle Linux Server release 6.5， 内核版本为 3.8.13-16.2.1.el6uek.x86_64
$ cat /proc/version
