Re: 7.3 upgrade & disk space requirement

Only the Loadsource needs to have at least 70GB of usable space.
So if you if your loadsource is a 79GB drive and it is part of a raid set
it won't have 7oGB of Usable Space. WRKDSKSTS will show you the usable
space after raid. All the other drives can be any supported disk size.

me to do the upgrade (our BP has always done it before).

I'm hoping I'm misreading the disk space requirements. As I read this
section, I need 70 GB on my single partition 720 for 7.3. That would put
me at an uncomfortable level.

Load-source disk unit requirements
v IBM i 7.3 load-source disk size needs to be at least 35-70 GB depending
on the type of disk being used.
- Minimum of 35 GB for 520-byte sectors (DS8000, virtual disks with VIOS
as server)
- Minimum of 40 GB for 512-byte sectors (SVC, Storwize, virtual disks with
VIOS, VSCSI, or IBM i as
server)
- Minimum of 70 GB for Native-attached SAS/SCSI (520-byte or 4K sectors)
