Re: BRMS recovery

[Roberto José Etcheverry Romero <yggdrasil.raiker@xxxxxxxxx>]

i'm skeptical on the 12hours to init disk + 12 hours to add to asp. in
theory you should only have:
Time to init LoadSource + LIC + time to init and add the rest of the disks
(do not init before hand, the add to asp step does it for you). it does
seem to be a very big system. And, 5 hours for OS? whats the hardware
config?
Yesterday i finished a reload on a 520, v5r4m5. The worst part of that
reload are the 300 minutes for the LoadSource + another 240 for the other 7
disks. then, OS installs in 30 minutes and the restore runs from a custom
CL in about 10 hours. none of that with BRMS tough.
Remember that on modern systems you can start the RAID (if you need to) and
then continue working, it will treat it as a disk rebuild and let you
continue with the OS and restore (albeit, slower than full performance of
course).


Best Regards,

Roberto
