And even in the SAS world, the SAS disks for i have a different FC than the
ones for AIX/VIOS have they not? i believe the 512 / 522 byte x sector is
still an issue...
At least on the Power6 machine i recently configured on the SPT they had

have a different FRU, wouldn't do it on a PROD machine but in my lab they

In the POWER Systems SAS era all the new drives are the same for IBM i
and AIX and VIOS. They are NOT the same code as for SAN or xSeries world.

IBM Sources their disks from multiple vendors so you may see Seagate
Hitachi, Quantum and others if you look at the Manufacturer part of the
label. That is not relevant to IBM i. The code that is loaded to the
controller for these drives is specifically for IBM i. The code is
'owned' by IBM and is unique to i. There are capabilities in there that
other drives do not have and these capabilities are leveraged by the
O/S. These drives ALSO report in with a Feature Code so that they can be
recognized and used. Without that no go.
SO you can go find an ''identical'' drive from the manufacturer and put
it into your power system. And it won't work because it doesn't have the
correct code and thus is not capable of doing the work. It also doesn't
have the correct FC so the server won't even try to use it.

Now I've got a question:
Has anybody *tried* whether the Mod. 270-2248 would accept disks beyond
Specifically, FC 4326 Seagate Model Number ST336753LC 35 GB 15k RPM

Or is it perfectly clear that this will not work?
I've seen some sources indicating V5R2 would be needed for that.
And even that an external tower with a new controller might be required.
I'm still asking because I've been offered a set of these drives.
As I understand it, an upgrade to V5R2 would probably not be feasible;
and an additional tower definitely.

After all, these appear to be 3-4 yrs younger. However, for IBM Hitachi

that the IBM iSeries drives were somewhat notorious for failing.

The following PTFs are installed (among many others):

I don't understand what the (2036) means in this PTF description.
This is the newest PTF installed:
MF27704 SPT: Incorrout-HLIC-94xx DISK
14-03-02 APAR corrigé: MA24666
Interestingly, one of the references below mentions:
MF27706 Changes to support downloading of new code for 67xx DASD.
I was wondering whether *that* might possibly enable the use of newer

Thanks a lot for your reading time, and for any input of yours.
