P670 internal disks performance

[admincff]

Hi,

I have eights partitions on ea p670 with each 2 internal mirrorred disks.
I have made standard installation of AX 5.2 for each partition.
But i have a real Pb of disk performance...
Installation of Oracle is very very long ....
How can check if disks and/or scsi Adapter are well configured ???

Has anyone encoutered such a pb ???
