How do I attach an IBM System Storage N Series NFS mount to an IBM iSeries (AS/400)?

I have an iSeries model 520 and want to add more storage to it. My drive bays are full, so I want to use an IBM System Storage 3300. Is anyone familiar with how to configure and add the storage so the iSeries will recognize it?

According to IBM's latest System Storage DS3000 Interoperability Matrix (http://www-03.ibm.com/systems/resources/systems_storage_disk_ds3000_pdf_interop.pdf), the DS3300 isn't directly compatible with the iSeries.

I know, but if I configure the DS3300 to work with NFS I understand it is possible to connect it to the network so that the iSeries will recognize it and use it as additional storage.


Assuming that the DS3300 is somehow accessible via NFS, then your 520 should be able to mount over the NFS export just as it does for any other.

But I wouldn't consider it "additional storage" exactly. Permissions, ownership, control by operating system -- you're essentially simply accessing files on a remote system. Not significantly different from accessing files on a share from a Windows box via /QNTC. (...which is probably cheaper, but that's beside the point.)

If you're familiar with NFS and have an export handy, you can probably learn as much as anyone can tell you simply by mounting over it from your 520. It's been some 10 years since I needed to do any NFS work. Was pretty easy going to HP boxes at that time. I've also used NFS in some limited Windows networks.

I have no idea how the DS3300 storage would be exposed. What other boxes are accessing it?

Gary has a very correct interpretation of how things might go. IFS stream-file stuff is probably "workable". But database-related stuff, including *PGMs and related objects, is _probably_ out of reach. I'm running into some systems with far more stuff outside of /QSYS.LIB than inside, so _maybe_ you can make it work.

But don't bet the business on it without understanding Gary's concerns.
