st_ats_enabled kernel parameter

Bruno Cunha — Wed, 20 Mar 2002 09:32:17 GMT

Hello all, does anyone knows if this kernel parameter exists in HP-UX 10.20 and what is called ? Since I read that st_ats_enabled was only introduced in HP-UX 11.0 and 11i. Thanks

Hi,

Executing the following command on a hp-ux 10.20 machine:# echo "st_ats_enabled/D" | adb /stand/vmunix /dev/kmem
st_ats_enabled:
st_ats_enabled: 1

indicates that the kernel param is there.
It is not on the list of configurable
kernel-params in SAM though.

st_ats_enabled was a parameter built in to the kernel, but was NOT a tuneable one until very recently, in 11i if i remember correctly

Hi,

I could see the st_ats_enabled kernel parameter in HPUX 10.20 A OS in HP Workstation.

But there is no decribtion about it. I think it is "SCSI Tape" related parameter.

st_ats_enabled for 10.20:

Install PHKL_20590:
( SR: 8606102798 DTS: JAGab68793)
This patch completes the implementation of the tunable "st_ats_enabled" which was initiated with patch PHKL_20063.
The original implementation was incomplete and did not work under all circumstances.
