Patching FCAL Loops (V880)

Today's tech tip concerns the good old Sun V880 (also the V890 and the V880Z). These machines can have two disk backplanes in them and (ideally) you should have arranged a dual loop so that the disks are all accessible via independent paths. When you go to test your install, sunvts crashes with some obscure error about the backplane firmware revision. Being good little administrators, you respond by downloading the patch 117814 (current revision is 01) and trying to install it. You run:

# luxadm display FCloop

as per the instructions, realise that at least one of your boards is down-rev. You boot into single-user mode, do the upgrade, wait the required half hour, boot into multiuser and check the firmware revision. It hasn't changed.

You can repeat this action as many times as you like but nothing will happen...


Tech Tip: It doesn't work under Solaris 9. I have no idea why. Grab another disk, wack Solaris 8 on it. Boot it in single-user mode, run the patch and "Bob'sOzg's Your Uncle". Boot back on your old disks and check the revision - just like a bought one.

Ack, why did they break that? Hope that wasn't a production machine...
