The mirroring instructions for both >those OSes assumed you'd a working system first. For software RAID (Solaris DiskSuite aka Volume Manager, Tru64 LSM), both Solaris and Tru64 require you to install the OS first and mirror it later. For hardware RAID, you would typically use a stand-alone RAID configuration tool before installing the OS. I found the Solaris 10 installer looked pretty but I was presented with a set of several hundred packages with (as far as I could find) no immediate indication of dependencies. This made the installation somewhat trial and error: Pick a collection of packages that looked useful/relevant. Move forward a few steps and get told that package SUNWfoo needs package SUNWbar. Go back to package selection and fix that. Iterate multiple times. >I'm also not sure that the onward march of disk-size is strictly relevant. >Were I building a PC-based RAID, I'd make sure I bought an >appropriately-sized spare disk at the same time as the rest of the set. Solaris requires that all disks in a RAID set have the same firmware version (though this isn't documented very well). Tru64 requires that both system disks have the same SCSI disk type. -- Peter Jeremy
