SuSE 9.2 - Proliant 380 G3

Anybody tried to install the drivers included in the Proliant Support Pack for SLES9?, installed some fancy things (like the storage configuration tool), but couldn't make work the important things like the SmartArray driver. The server is running about 2 months already, but i'm trying to install the PSP because of two problems i've found: Yesterday tried to attach an old DLT IV drive to it and it wasn't detected. Sometimes when moving ~20GB of data from one filesystem to another it seems to freeze for some seconds. All the filesystems are on a hardware RAID5 (SmartArray) Are any difference between the SmartArray module supplied with SuSE Pro 9.2 and the one from the Proliant Support Pack?? Thanks in advance Ciro
