Seriously though, if I thought that Netapp hardware was the kind of thing that would "go up in a puff of smoke" from something as simple as an incorrect disk drive, I never would have let it in my server room in the first place. These are well-built robust machines. In my experience, they're not going to go tits up over something as basic as that. I can't envision anything bad happening worse than the disk just not being used. This isn't like a plain old scsi bus where connecting a device incorrectly can short the whole bus out (I've scene a couple of sparcstations die that way). These things are designed to be hot-swappable. If the disk is for some reason the wrong size or manufacturer or type, it will a) probably not even fit in the shelf, or b) just not get recognized by the filer.
If there's some great risk of plugging in an unknown disk, I'd like to hear about it.
I know. I trust NetApp pretty much, too. We had a program where we were trying to get a firmware installed on a lot of DEC 4GB disks that were lying around so that they would work with the netapp filer. We had marginal success and some DEC disks worked with netapp firmware and some did not. We even had some disks sent to netapp for reinstalling firmware. This was long ago when we had 220s, 330s, and either a 320 or a 230 (I forget which) and netapp was young and doing alot to help us and we appreciated it. We marked the modified firmware disks, but had some strange ones sitting in our spare storage. I was hoping someone could send me some way of deciphering the CZHZ-ZZ or RZ43R-DX or whatever because there were no other indications of capacity or type, because I am not really pressed to do this immediately (I have hot spares & cold spares available). I suppose I will just plug it in and see if it is recognized. Thank you.

Thanks, I will. ... not. Your users love you!
Or, the whole filer might go up in a big puff of smoke. Try it and let us know!
