Hi 
How can I programmatically list disks and their sizes in Solaris? 
Is there a way to extract lets say scsi disks from that list?
Thanks

You would typically use the facilities provided by libdevinfo (which reads
the kernel device tree) to do this. Not sure about extracting SCSI disks
only, but I guess you could try a SCSI enquiry against each.

I doubt there is a ready command for this.
The easiest, IMHO, would be to write a script that parses 
output of "format" (which can be run non-interactively and gives
the list of disks and their sizes - well, at least one can 
calculate the sizes, assuming all sectors are 512 bytes).
"format" also gives the device path, from which the driver name 
can be derived. Knowing which drivers are SCSI ones 
(SUNW,fas SUNW,scsi etc.), helps to select the SCSI disks.

Andrei

guess iostat -En might help you if you want the sizes of disks(not the
size of slices in disk).
 For more info man iostat.

Sorry, I missed the bit about sizes, that can be easily retrieved from the
vtoc, check out read_vtoc(3X) or the ioctl it calls (DKIOCGEOM) in dkio(7I)
