Thank you all for sharing your thoughts. I do agree that the safe way to move forward is to simply replace the drive. I was hoping for a way to schedule xfs_check/xfs_repair at boot similar to how fsck can be scheduled in linux, as a way to hold onto the drive for a while longer. Besides a few things I would like to preserve, I seem to be having issues with the units loosing connection with DINA after booting sash/fx, anything past that point and they do not seem to see the boot server, at all, so I am for the moment unable to carry out a fresh install from the network. Moreover, the sled that contains the drive seems to be stuck inside the Octane tray, and I am a bit wary about the possibility of the plastic caddy breaking off. I will investigate both issues further and will install a new drive when I have sorted both things out.

As for the dual head configuration, I was aware there could be issues with the standard PSU, and that the SolidImpact cards are specially demanding on that regard. While no power ratings are visible, I am working with the assumption that the PSU in question is a #6064470 by ITT PowerSystems which, if I am not mistaken, seems to be rated at around 1 kW (around 500 W on the DC rails). The two warning labels match with pictures I found online, and the distribution of screws on the top of the case would be exactly the same. The power rating label on this PSU is affixed to one side of the case which is in contact with the computer case, hence concealed unless you physically pull the PSU, but I am fairly certain it is the same model.

I tried reconfiguring the kernel and it seems to have done the trick. Either that triggered an update, or something else changed since the last time I tried which was, admitedly, some time ago. I now get video from GIO0 (the one at the bottom) at PROM and some sort of out of sync signal from GIO1 (the one on top). However, the moment IRIX boots I get two good signals on both monitors, and I can access both desktops with no issues whatsoever.



I will check the PSU in more detail to confirm it will be safe to run this configuration. I have unfortunately not found much information online regarding the different models, their power ratings or power consumption estimates for different configurations.

As I said, thanks much, this was good info all around!
