1. I know there is only one hard disk, so why are there different serial numbers?

2. I think this might be what is giving me confusing results for df -h. I get a lot of Filesystem entries listed (with capacity and free space, etc).
Is there a command that will give the sum total capacity and space? That would be much easier for me to understand at the moment.

Many thanks in advance!

I would double check there is really only one.
If true, it might be there was three more hard disks but they were removed. You can run
Code:
devfsadm -v

or
Code:
cfgadm -C
cfgadm -al

to clarify.

Some filesystems aren't backed by disk so the size the reports might confuse you. Some filesystems might be mounted more than once and their size shouldn't be summed more than once.
If you use zfs, df output might be even more complex to understand ...
