Re: Multiple paths to library changer on 3584 LTO

As you have seen you can have two controls paths. Unfortunately only one may be
active at a time. Also there is no automatic failover for the 3584. However,
you have done a good thing. It is good to have two controls paths. Then if
there is a failure you can manually update the control path to the other path.

Hi,
When I issue a "show libr" I can see an autochanger list. Does that mean I can
configure multiple paths to my library?
How do I do that? I have enabled an additional control path on my library so
under AIX I have /dev/smc0 and /dev/smc1.
I can access both of them, but how do I tell TSM to use both?
When I try to define an additional I get this response:
ANR1723E A path is already defined using TSM01 and LIB_3584_1
In that case I would not have to bother with control paths anymore... Once an
IBM CE replaced drive F1R01
- and we all forgot that the control path was running over F1R01 so the library
was unavailable at that time....
=== Library LIB_3584_1 (type SCSI):
