[CentOS] CentOS 6.6: Lost connection to tape library

OK. That's great. I would try following

1. Boot using working kernel.
2. Verify the associated modules loaded.
3. Boot into new kernel, verify the same sets of modules are loaded or not.
4. Like it said in one of the post below, you can try 'modinfo `hpsa module
name*` from newer kernel. If no result found, install the kmod-hpsa package
that's matching with the kernel version.

* I am not sure about the exact module name.

5. I would prefer a reboot after kmod package installation.

Cheers,
