SYMBDSNAP_SDK[3943]: Failed to open device: /dev/symbdsnapctl, errno: 2
在Linux的日志/var/log/message里面看到下面錯(cuò)誤信息：
Oct 26 09:48:42 xxxxxxx SYMBDSNAP_SDK[3943]: Failed to open device: /dev/symbdsnapctl, errno: 2.
Google搜索了一下，發(fā)現(xiàn)出現(xiàn)這個(gè)錯(cuò)誤的原因：
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.
https://access.redhat.com/site/articles/3078
For instance:
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.
SymBDSnap是針對(duì)AOFO-L的設(shè)備名。 ? 啟用AOFO-L需要是相應(yīng)內(nèi)核版本的支持，而不是某些Linux版本。 ? 請(qǐng)參考下面的URL，對(duì)比每個(gè)REDHAT版本相應(yīng)的內(nèi)核版本， ? 可知REDHAT使用的內(nèi)核版本不再Backup Exec的兼容性列表中。 ? https://access.redhat.com/site/articles/3078 ? 實(shí)例說(shuō)明： ? Backup Exec 2012軟件兼容性列表中說(shuō)Redhat 6 update 1支持 AOFO-L。 ? Redhat說(shuō)Redhat 6 update 1的內(nèi)核版本是 2.6.32-131.0.15。 ? AOFO-L支持2.6.32-131.0.15內(nèi)核版本。如果內(nèi)核版本是 ? 2.6.32-220或者更新的版本，AOFO-L在2013.8.12以后就不被支持了。?
剛好出現(xiàn)錯(cuò)誤的系版本為Oracle Linux Server release 5.7， 內(nèi)核版本為 2.6.32-200.13.1.el5uek
$ cat /proc/version ? Linux version 2.6.32-200.13.1.el5uek (mockbuild@ca-build9.us.oracle.com) (gcc version 4.1.2 20080704 (Red Hat 4.1.2-50)) #1 SMP Wed Jul 27 21:02:33 EDT 2011所以出現(xiàn)了上述錯(cuò)誤。不過(guò)可以忽略此消息。執(zhí)行備份而無(wú)需使用AOFO L。
??
總結(jié)
