Hi List.

I've got scsiinfo-1.6 from RedHat's ftp site and would like to use it
via the command line (I've got only 8 MB of RAM on this box, don't
need more for regular work, and have to make 100 disks fault-tolerant,
so they do AWRE and ARRE).
Doing scsiinfo -Xe /dev/sdb I get

0 0 ......

while the numbers correspond to the values given in the verbose display
from scsiinfo -e. I have to change the first two numbers to 1, right ?
What about EER, PER, DTE, DCR ?
And how do I write the new values back ? The usage says "expert use only",
so I beg the experts to step forward and share some of their power with
me :-)
THe disks are to be used in standalone field data recording and we would
like not to lose a single byte of the data recorded, so ... all features
of newer (SCSI-2) disks are needed.
UNfortunately I only managed to find a very large SCSI-2 documentation,
it's like finding a needle in a haystack...

Well, I finally found a working acroread, an d despite the fact that the 
index of scsi2.pdf is completely _wrong_ I think I've found the interesting
parts. But I might have missed something very important, so again: if the
SCSI wizards have remarks on the procedure, those will be highly appreciated.

I will do 

scsiinfo -Xe /dev/sdx

replace the first two numbers (AWRE and ARRE) by 1's, set EER, PER, DTE, DCR
to 0 (in fact they are alraedy zeroed) and write the whole thing back using

scsiinfo -SRXe 1 1 ......

Any caveats ?
