Thanks Jeff,

<1.      You can have 2 fiber connections per tape drive.  Each with a
<separate device.  The first cfgmgr will show one path and the second
will
<show the second path.

I already know I will see 2 rmtX definitions from AIX - 1 down each FC
path.

<2.      I believe AIX can do this with multiple device path, but I am
not
<sure of specifics.

What I am looking for is specifics.

<What advantage do you hope to gain from multi-pathing?

What I am hoping to gain is redundancy.  If an adapter, a switch, a port
on the tape drive, or a link between a device goes down, I want to be
able to access all my tape drives from the 2nd redundant connection.
