For Linux:  Use hdparm -W0 on all your drives to turn write cache off.

For Windows (2k) I'd expect something similar for XP.
go to My Computer -> Right click on Manage --> In computer management 
--> Device Manager --> Pick Disk Drives ---> Right click on the Disk, go 
to Properties --> Pick the disk properties tab and you should see a 
checkbox with writecache enabled.

I dont know about Solaris.

HTH,
