power issues cause drives to 'disappear'

[Marc G. Fournier]

I have 5 servers running right now ... 3 with hardware raid, 2 with vinum 
... all RAID5 ... and I'm getting some odd behaviour that I really can't 
explain ...

All the servesr are using Seagate drives ... one is using 72G ones, the 
others all 36G, same models ... all hot swap ...

neptune (72g drives), about a month ago or so, one drive went "stale" ... 
I had screwed up when I build the vinum array, and did it as a concat vs 
raid5, so lost everything ... my fault ... but, when I rebuilt it as 
raid5, I included all the drives, including teh one that said it had 'gone 
bad' ...

mars (36G drives), same thing ... drive on a raid5 went "stale" ... ran a 
vinum start on the drive, everything came back fine and periodic checks 
showed it as being fine ...

today, pluto, 36G drives with an iir controller "lost a drive" ... I'm 
suspecting that if I 'revive' it (assuming I can figure out how to), it 
too will prove to be fine ...

If the drive didn't revive, then I'd think bad hard drive ... but they 
are, and run fine afterwards ...

Now, unfortunately, I just checked both mars/neptune, and see taht I have 
again a stale drive on each ... I didn't think last time to record which 
drive was stale, so don't know if its the same ones :(  I'm going to do 
that this time though ...

So, the question is ... would a power 'flux' cause something like this?
