Re: 7.3 upgrade & disk space requirement

What size is the load source drive. The real requirement is that physical drive must be 70Gb in size, it does not need 70 gig free. What it does need is sufficient space to be able to expand the space set aside for the LIC.

The load source for virtual partitions is 35GB. The same rule applies in that it must have sufficient room to expand the LIC space.

Currently on OS/400 - IBMi partitions all native attached drives must be
the same physical capacity.
So All 35GB or ALL 70GB or 128GB or 283GB in the Same Set. Same is true for
mirrored pairs.
So with 7.3 and 70GB physical drives unless you monkey with RAID or Mirror
the loadsource it may be an issue.

Is it still are requirement that all the disks in a RAID set are the same
size or only the amount of space on each drive will be limited to the
smallest drive?

If so, you will need to build a RAID set of drives with at least 70GB
usable each, after the RAID is configured.

You can mirror two drives or as small as 3 drive RAID-5 set. For
performance I would build a RAID set with 4 or more drives. But newer
controllers negate that old rule of thumb.

What are the current rules?

More importantly, what hardware do you have, especially RAID card?

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.
