Solaris

Hey guys,
I recently replaced the heatsinks on two different V240's. Repasted and replaced them myself. After attempting to bring them back up, there was no display coming from the KVM. I figured it was a matter of environment in OBP and attempted to get to the OK prompt from the ALOM. I let the login in expire, and the OK prompt never came. Went in through the ALOM and sent a break command and tried console -f. Still nothing. I have scoured the internet and exhausted all resources at my disposal to no avail. It seems to me that something I did is causing the system to hang up, or perhaps enter a boot cycle that I can't break. I've been working this over a week and am drained. Any advice or suggestions are welcomed. ANY. Thank you in advanced.

P.S. It may be simpler than I am thinking, because I am experiencing the same exact issues on two separate servers... just a thought.

First, you need CPU's to get an OK prompt. I think you screwed up your CPU's somehow. I have no 240's left so this is from imperfect memory. I used to be able to defeat the case switch so I could run the 240 with the cover off. Those heat sinks have a couple of fans on each one. Are the blades spinning? (BTW, over the last few years that I had 240's I never saw a replacement heat sink that used paste. I assume that yours required that paste you used.) Try reseating the CPU's. This is probably the key. My guess is that you reseated all 4 cpu's wrong. The next most likely idea is that you got 4 bum replacement heat sinks. A final thought is maybe you forgot to plug the heat sinks in. Check for spinning heat sink fan blades will quickly disprove the last two ideas.

In the worst case buy some replacement 240's on ebay. And when the heat sink fans break, hire a tech to replace the heat sinks rather than doing it yourself.

we replace the fans on v125 without removing the heatsink (I think its the same as in v240), its not very hard.
perhaps you should check if RAM modules are seated properly, too.

What do you mean by this??? You let what login expire?

Are you saying that from a cold power up, you get no output whatsoever?

You mention a KVM. This is connected to which port on the V240?

Is everything definitely connected the same way it was before you worked on the box?

If you plug into the serial port on a V240 and power it on you get a chance to login to ALOM. If you login to ALOM, you can use the "console" command to turn the serial port into a system console. This also happens if you just let ALOM time out without logging in to it. If you don't know the ALOM admin password this is what you have to do.

@Perderabo.........

Yes, agreed, but I'm asking the OP whether there is any output at all. I'm wondering whether he does have control of the system controller (SC>) and the main processor is not configured to auto-boot. If so, perhaps he needs to tell the SC to 'poweron' the main box before giving the 'console' command, otherwise he's connecting a console to a dead box.

That's where I'm coming from. Do you think that's a possible scenario?

@hicksd8


What you suggest is possible. ALOM is alive while the system is powered off. You can signon to ALOM and then use the "poweron" command to apply power to box. But there is also a power button. If this guy has been working on two dead V240's for a full week, I would assume that he is applying power. If not, then I would certainly recommend powering the system on as the very next thing to try.
