No, not in software, only with the right hardware.

I assume you mean scsi raid5 because fibre chanel or SSA disks are different.

As scsi raid5 in AIX software is not possible, there is no documentation.

For the information about the scsi hardware raid5 adapters try a google for:
site:ibm.com aix raid adapter systemp
site:ibm.com aix raid adapter systemp - Google Search
to get you started.

Systems up to power5 need a pci adapter for scsi raid5.
Some of these systems, like the 7026 H80 / M80 - p660 will also need an external storage enclosure because you can only fit 2 disks in the system unit.

Most power5 and power6 systems can accept a scsi raid enablement card that enhances the onboard scsi adapter to allow raid5 use of internal or external disks.

What is your systems machine type and model? Then we can look up the adapters and disk configurations that your system can use.

lsconf | head
will show your machine type and model

lsdev -Cc disk
and
lsdev -Cs scsi
will show the scsi disks and controllers in your system

Based on this IBM page:
IBM Techdocs FAQ: Can external SCSI disk drives be configured as part of the same RAID array as the internal SCSI disk drives on the System p models 51A, 52A, and 55A?

I think you need "fc=1908, Dual Channel SCSI RAID Enablement Daughter Card" for your 9110-51A

There may be other options.

Call IBM or a reseller and ask if this is correct and how much they are.
