Hi!
 
I have a problem with my new server sun
x4100(http://www.sun.com/servers/entry/x4100/specs.xml).
 
Ffirmware is 6.14.04.00 retrivied from sun's site.
 
I cannot get more than 3 MB/s when writing to it.
 
#pciconf -lv
--- CUT ---
mpt0@pci2:3:0:  class=0x010000 card=0x30601000 chip=0x00501000 rev=0x02 hdr=0x00
    vendor   = 'LSI Logic (Was: Symbios Logic, NCR)'
    class    = mass storage
    subclass = SCSI
--- CUT ---
 
 
when i run blogbench, squid -z, or any other software systat return
da0 with 3.0MB/s and 1005 busy.
 
I have tried both with and without RAID configured through the
controller and i get same results.
 
Some times my dmesg return this message :
