Linux CentOS 6.6, lin tape?

[crowder]

I read in an IBM article that lin tape is not supported in Redhat 6.x and above. Has anyone used lin tape in CentOS/RH 6.x? If not, what is the alternatives?

Not true (well, 6.6 probably is not supported yet, but 6.x in general is)....just look at the lin_tape fix list:

RHEL 6.6 has kernel issues. Red Hat has a bugzilla for this which is essentially a down level patch to RHEL 6.5

See this.
