Thanks, guessed that much after goofing around with it. Now to find a 3rd party vendor in the UK ...

The problem is not with the qualified disk file. He has taken a non Netapp drive (1: SEAGATE ST336753FC 0005 17.0GB ( 71687367 512B/sect) and put it in his system. It is even showing Seagate's Firmware (0005). The reason it is not showing the full formatted capacity is the drive is a 512 sector (ZCS) and not formatted to 520 sectors (BCS). You need to remove the drives and purchase qualified one from Netapp or one of the 3rd party vendors out there.

You can download the current qual_devices file at: http://now.netapp.com/NOW/download/tools/diskfw/ see the link at the very top of this page. Hope this helps.

Hi - thanks John. They don't want to work. Not 100% sure where they came from to be honest. But the NetApps does recognise them ... just only 17gb of them and not the 36gb.

As each install takes forever, 8 floppy disks? Are they having a laugh? Anyway doing a fresh install with my 2 x 36gb 15K drives and 3 x 36gb 10k drives installed. It chooses to use the 2 15k drives as vol0 - I had no choice in this matter it just did it, maybe because it sees these as the "smallest" drives? So ended up again with the system reporting vol0 as being made up of 2 x 17gb drives.

So did another install, this time with 5 x 10k 36gb drives, all went well. All disks shown as expected. I then edited the qual_devices file and added an entry for my 15k drives based on the format shown and did a reboot. Rebooted okay, no errors at all. So pulled one of the data drives and replaced it with a 15k drive. It then reports an error with qual_devices file:

Tue Sep 27 09:10:02 GMT [disk.dynamicqual.failure.invalidFile:error]: Device qualification information file (/etc/qual_devices) is invalid. Please refer to the qual_devices man page for corrective action. This problem must be corrected within 72 hour(s) to avoid a forced system shutdown. The following disk(s) remain unqualified: 1.3 etc...

So the NetApps must do some sort of sanity check on this file when disks are added. Again the disk is reported as 17gb only. Plug the 10k 36gb drive back in and all is well again.

Anyway, took a while but worth a go I suppose and answered a few questions.

Doing a search on NOW for "ST336753FC" gives only one reply in the NOW Forums to do with a FAS920, which wasn't much help but thought I'd include it in my reply anyway.

X271A -36GB 15K sysconfig output (from parts finder): Seagate>>>NETAPP X271_S15K3036F15 ?Cheetah 36GB 15K ST336753FC

Thanks - Julian.

Well, if you're just playing, you could certainly try to just add a new entry to the qual_devices line and see what happens. But you'll be on your own.

There's no real reason they won't work together, it's just that Netapp won't support you if something goes wrong. *grin*

...

From the look of the file, all you'd need to add is a line like this:

 D  SEAGATE  ST336753FC 0002  512

and see what happens. you might need a reboot to make it take effect after you do the edit. The key is probably the '512' part, since you don't want to mess around with the Zone Checksums (or is it block? I can't remember...) since you disk most likely is setup for 512 byte blocks, not the 520 byte blocks.

Good luck, John
