mix fc and tape devices

I have a problem with some partitions.

In one of them I have this two fiber channel.

ide0 Defined 07-08 ATA/IDE Controller Device
sisscsia0 Available 00-08 PCI-X Dual Channel Ultra320 SCSI Adapter

In my tape devices I have this

lsdev -c tape

In my disk devices I have this

lsdev -c disk
hdisk0 Available 00-08-00-5,0 16 Bit LVD SCSI Disk Drive
hdisk1 Available 00-08-00-8,0 16 Bit LVD SCSI Disk Drive
hdisk2 Available 04-08-02 1742-900 (900) Disk Array Device
hdisk3 Available 04-08-02 1742-900 (900) Disk Array Device

As you can see I have a mix in my devices in on of them 04-08 I have tape and disk. and in the 05-08 I have only tape.

The thing that I want to do is that my both fc see only the disk, because if one of them fails I have the other one.

In the switch san. I have the zones I have to take off the zone of this fiber to the tape.

In my client storage software I add my second fc.

In aix I dont do anything.

Im confused what I have to do.

Thanks for your tips

Aix is 5.3, the storage is DS4500
