I have a p520 that I'm have trouble getting some hard disks to work with. I'll put 2 drives in the front bays, and they will show up but only as defined. When I try to format the drives it says that I need to run diagnostics on them, when I run diagnostics on them it says there is a corrupt formatting on them. I tried putting in a different set of drives and I get the exact same problem.

When I boot from the AIX install CD's, it does not show any drives present for install.

This is not the first time I've had problems with 9111-520s. We also have 9131-520s and those machines give me no problems at all.

Let me know if you need any more information or clarification.

Hi

It could be that those disks are too new for the AIX media you're using. Could you please post the Type/model of your disks.

Sounds like you have a raid controller. You'll need to format the drives for raid, 522 instead of 512 bytes per sector I think.
Format them, then either create an array, or not of you just want jbod or AIX mirroring.
Then AIX should recognise then and install OK.
