The following error, want to quickly figure out what dependencies need to be installed, the error message may be written to the file, I have here named err, re-analysis of the installation RPM. From avoiding take up too much space, but here is the removal of the first two.
Error: the Package: the lpfc-kmod-ELX-Xen-8.2.2.33-1.rhel5u11.x86_64 (/kmod-elx-lpfc-xen-8.2.2.33-1.rhel5u11.x86_64)

. 1, performing awk '{print $ 2}' err | grep kernel | cut -d "(" -f 2 | cut -d ")" -f 1 to obtain the following results:

There are various methods, it should be achieved through good word python.
