Esteemed colleagues,
We can't get the RAID configuration utility to give us the amount of
disk space we think we ought to have on our main file server. We used to
have 4 72Gb drives in a RAID-5. We put two more 72Gb drives into the
server, and followed the directions to "expand the array" using HP's
ACU-XE program. The directions say this can take 10-15 minutes per Gb,
and it took lots more time than that, but finally, it was done.
So, here are the figures for drive space we are now working with, and
they just don't add up.
In ACU-XE:
- The original drive space is listed as 208378 Mb
This is roughly equivalent to 69460, which is the physical drive
capacity reported by the System Management Homepage, times 3, leaving
out the 4th drive to make the RAID-5, which comes out to 208380. This is
fine.
- The new "unused space" is listed as 166707 Mb
This is actually quite a bit more than 69460 times the two
drives we added, which would be 138920. This is confusing to me, and the
figures do not add up.
- When I go to "extend size" in ACU-XE, the maximum size I can extend
the array to is 261116. This is not even as much space as adding one
drive to the array should give us, and we've added two drives! This
really doesn't add up.
More figures:
If you add the two numbers in ACU-XE (original plus unused), I come up
with 375085.
If you figure out what 5 times 69460 would be, it comes up to 347300.
Either one of these numbers would be fine with us, but 261116 is just
plain not enough!
Thanks in advance for your help.
