Infrastructure Software

I have this odd problem:

I have a pilot project consisting of handful of Sunray 1g, 2, 270 and 2fs DTU's connected to a pair of T2000's running SRSS 3.1 w/ 120879-05.

The problem that we are seeing is that when the Sunray 2's are using the new Type 7 keyboard/mouse kit and they go to sleep for a long time (say 1-2 hours), the keyboard is no longer functional until we either power cycle the DTU or unplug the keyboard. If the mouse is connected via the usb hub built into the keyboard, then the mouse will show that it has power, but it will not wake the system up.

If we connect the type 7 mouse into one USB port and the keyboard into another, then the mouse is able to wake the system up, but the keyboard is unresponsive until we either power cycle the unit, plug/unplug the keyboard or wait 1-2 minutes. If we use a smart card to wake the system up, the keyboard is still unresponsive.

Other than the keyboard and mouse, no other USB devices are connected to the DTU.

We are not seeing this issue with older Type 6 keyboards. We also do not see this issue on the SunRay 270 or 1g's. I have not yet had a chance to do full testing on the single SunRay 2fs I have, but so far I have not seen any issues with the 2fs.

We are seeing this problem with both the current firmware (3.1_120879-05) and the firmware that came from the factory. The SunRay server is fully patched up with all current solaris patches.

The units are running in cam mode with a custom script in addition to dtsession. We have tried using the xset hack (including running it every 60 seconds in the background) to disable dmps and fbpm (we still want the screen to blank after 300 seconds), but to no avail. (I'm not positive that xset is making any changes since dtsession also seems to run its own power management utilities and the two may be fighting each other)

Based on what I'm seeing, I suspect an interaction between the system and the usb hub in the type 7 keyboards. Why this does not happen with the 270's I do not know.

I have searched through sunsolve, the SunRay-users archives and "the google", but to no avail.
