I checked the disklabel of sd0c and it showed partition a: having
1024000 sectors with offset 0. sd01a is exactly the same. raid0 (which
is a raid1 composing of sd1a and sd0a) has 1023872 sectors with offset
0. Note that 1023872 was given by disklabel raid0 > disklabel.raid0
before. 1024000 - 1023872 is 128, which happens to be raid0's sectors
Why is using 1023872? is the 128 reserved for the raid disk label?

I was curious if sd0a had read write problems. So I changed sd0a from
type RAID to 4.2BSD. newfs sd0a and it went fine. fsck sd0a had no
errors. After that successful test, I changed sd0a type back to RAID in
the disklabel (everything else remain the same).
Trying to get sd0a to be spare for raid0 again:
raidctl -a /dev/sd0a raid0
raidctl -vF component0 raid0
...reconstruct at around 7%...

On a positive note, I finally got a chance to take the alpha down and
replace the cmos battery so it would keep proper time and cmos settings
between long (like 2 min) of being shut off. It also helped with not
having to get into AlphaBIOS for NT each time the system power cycles.
You'd have to go into the cmos and set OpenVMS again, then reboot just
to get it to boot. CR2032 lithium battery cost $2.99 at Kmart and
