We don't show sda/sdb/usbN/scsi (at least if you have more than one scsi
card) because those are not reliable and can change from boot-to-boot
because they're assigned based on scan ordering and the order in which
the relevant modules are loaded. We're very cautious about protecting
users from dataloss where we can, so if a storage label is not
persistent / reliable, we decided to not use it.

We do plan to show different icons for disks based on their type as
Chris described further down in the thread, but I think those are for
USB vs local disk vs network disk. So if knowing a disk is pci vs scsi
is helpful in identifying a given disk, we could consider putting in the
hover information alongside the serial number.

Can you tell us a little bit more about your setup? I'm guessing it's a
desktop machine, right? What kind of drives do you have in it, how do
you use them? Are they all the same size and RAIDed, or does each have a
different OS, or...?

We're trying to design the UI to be as seamless as possibly for the
majority of users who would use a GUI to install Fedora, which we've
found is overwhelmingly laptop users who are necessarily limited to a
small max bound of disks. However, we still want it to work for other
cases.

We do display those if you hover over the drives. How do you know the
serial number - do you open up the box and look so you are sure?

If you want to see all of the information that gparted displays, I would
suggest using gparted. The installer environment is necessarily limited;
folks with more advanced use cases should use specialized software like
gparted in an environment meant for that for a better experience.

Right now if you select a disk in this screen and continue, we will try
to use any free space available on the disk. If there isn't enough free
space available we'll offer to shrink the FS for you. We will never
overwrite data on the disk unless you tell us to.

The new ui will have a section in the first screen of the storage spoke
for working with specialized disks - I don't think it's turned on in the
UI for Fedora and it won't be, but it will for RHEL - that has a tabular
format for working with iSCSI, hardware RAID, DASD/zFCP, and other SAN
devices.

Can you tell us a little bit more about what you were looking to do
here?
