As previously mentioned, sasinfo shows the number of SAS HBAs and their connectivity
to enclosures and ultimately disks.

Most systems also have one or more SATA HBAs, which use a different driver and needs a
different tool.

If you have a RAID HBA, then it could be using the mr_sas driver, with a different tool.

"prtconf -D" shows the device tree with driver attachments, which is sometimes reliably 
scriptable. The usual driver names are mpt_sas, mr_sas, mpt, ahci, pci-ide
