I am confused when converting direct attach to a SAN system
Our old system was had 12 127 15k rpm drives. We converted to an LPARed
system with 3 Luns.
#1 572000M 7,200 rpm
#2 191000M 7,200 rpm
#3 763000M 7,200 rpm
I don't have the exact break down but there is supposed to be 60 drives
allocated to the 3 luns.When we tried a test conversion this past weekend a
disk bottle neck occurred during part of the initial start up when selected
files were being reorged.
My thought on correcting the problem would be to:
1. Split the 3 luns into maybe 6 or more smaller units
2. Recreate the luns using 15k drives
3. Recreate the drives into 6 luns with 15k drives
Am on the correct track\?
Is there other option to consider?
TIA
