Re: How can I tell if I can add drives to my IBM i 7.5 Power 9?

What disks does it have today and what disk expansion does it have in 
place? Pretty much the only way to know. Potentially more disk 
expansions can be ordered and/or more SAS RAID cards installed.  If you 
have the available slots, starting a new RAID set is with near certainly 
acceptable. Exception would be if you've already added handfulls of 
disks several times to a particular SAS RAID Card pair and used up all 
the RAID sets.

We do occasionally get a "spend it or lose it" directive.  Which often ends up in stocking up on new laptops for the next year.
