William,

It depends on the library. The library has the ability to announce the
Changer through more than one fibre-channel. You should modify the setting
on the library and run cfgmgr again on AIX, one of the smc's will become
defined.

I just checked one of TSM Server, it has 2 Media Changer:

smc0  Available 0D-08-02 IBM 3584 Library Medium Changer (FCP)
smc1  Available 0H-08-02 IBM 3584 Library Medium Changer (FCP)

>From TSM Server, it only defines one Media Changer:
DEFINE PATH TSMSERVER LTO3584 SRCTYPE=SERVER DESTTYPE=LIBRARY
DEVICE=/dev/smc1 ONLINE=YES

My question is:
If only define  1 Media Changer, TSM Server can't use the second Media
Changer, then why does it need 2 Media Changer? If it define the
second Media Changer as following:

DEFINE PATH TSMSERVER LTO3584 SRCTYPE=SERVER DESTTYPE=LIBRARY
DEVICE=/dev/smc0 ONLINE=YES

Will TSM automatically use the second Media Changer?

TIA
