multipath

[ElHedi]

we are using linux Redhat native multipath for persistent binding
and this is done using the wwid in the /etc/multipath.conf
I do not know how to do for tapes?
is it possible to have multipathing for tapes
is there any tool under networker to control this
special thanks

Tpo my knowledge multipathing for tapes is not possible.
With Networker there is an additional difficulty, the control port of the jukebox is not "dynamic" but a fixed property of the library.
If this controlport changes the library becomes unavailable, so there is not much benefit in multipathing.
Depending on your infrastructure you can attach the tapes in your library to different fabrics but the control port issue will remain.
