SSD driver parameters

Hi all,

I have a sparc system ( M5000 ) installed with Solaris 10u10, in SAN with an IBM DS8000 storage, the system hba is a qlogic mod. qle2460 working with qlc driver

while disk driver is ssd.

IBM said me to configure the system with following parameters

set ssd:ssd_io_time=0x78
set ssd:ssd_retry_count=5
set ssd:ssd_max_throttle=8

but checking this value on system I find out below :

root@xssas1 # echo 'ssd_min_throttle/D' |mdb -k
ssd_min_throttle:
ssd_min_throttle:               8                       DEFAULT VALUE

root@xssas1 # echo 'ssd_io_time/D' |mdb -k
ssd_io_time:

Howdy, Stranger!
