CX300 won't boot

Hello everyone!
I have faced strange behavior of my old CX300 box. When it boots all drives try to initialise and after that every drive has two solid leds on: green and amber.

When I try to connect to any of SPs via HyperTerminal - nothing happens.

The amber led on back of both SPs blinks once in 2 or 3 seconds.

Any ideas how to bring the box to life?

Thank you in advance.

Re: CX300 won't boot

The Fault light on the SP blinks when booting up - the frequency of the blinks indicates the state of the boot process.

Stages:

1. once/4 seconds — BIOS activity.

2. once/second — POST activity.

3. four/second — booting.


Steady indicates fault


If the blinks stay in one stage, that indicates a problem in that stage. If the lights are blinking at the rate of one blink every four seconds, that means the BIOS activity has discovered an error and will not proceed to the next stage. If both fault lights on each SP are stuck in the same stage (BIOS), that may indicate a problem with the getting to the next stage (POST) where access to the Vault (or the OS) drives come into play. This may indicate a problem in the disks. and will probably require someone to troubleshoot the issue as you may have an issue with the Vault disks, or image on the vault disks.


SPA uses disks 0 for booting the array OS (disk 2 is a mirror of disk 0).


SPB uses disks 1 for booting the array OS (disk 3 is a mirror of disk 0).


You could power off the array, then remove all but the first disk (disk 0) in the DPE (first set of disks) and disconnect any other DAE's (remember to label the DAE cables so that you get the cables back in the correct position) and remove SPB, then power on just SPA - if that boots, you will still get some faults as the other SP is removed and the disks are all removed except for disk 0, but at least you could see if the SP will boot. You could then try the same steps with SPB and its boot disk (disk 1) and see if SPB boots.

Glen, thanks a lot for your answer. Will try to do that tomorrow.

Re: CX300 won't boot

Glen, tried the thing you've suggested - no luck.

When I power on the box the HDD lights with steady amber, the green LED blinks a couple of times and becoms steady too.

No output through hyper terminal.

Tried this on both SPs with the other pulled out and one HDD in array - 0 for SPA and 1 for SPB

Re: CX300 won't boot

Miromix, Can you please brief us what was the last action you made before having this issue?

Also, in your case, I will do what Glen recommended. I will first remove both SPs while the array is powered off then i will reseat SPA first and try to boot. if that was not successful then i will go for other alternatives like installing recovery image or so.

Hope that helps

Re: CX300 won't boot

Mohammed, nothing special was done to the box. It just stood powered off for a year.

What other alternatives are you talking about? I cannot get access to SPs through Hyper Terminal...

Re: CX300 won't boot

You should be able to use Hyperterminal. May be the connection parameters are incorrect. Can you copy and paste Hyperterminal Connection settings you are using?

Hope that helps

Re: CX300 won't boot

In my old laptop "with serial port"  I connected to a CX3-20 array using this settings 9600-8-N-1-N and it worked fine

Hope that helps

Re: CX300 won't boot

Mohammed, I am using the exact same settings on my old XP laptop. The cable is from CX300 box. I tested the cable on working CX500 system and its okay. Both systems are using the same cable (found on powerlink)

And I still have no connection to SP in HyperTerminal.
