EMC – CX POST output

Following on from my two previous posts on the CLARiiON POST and troubleshooting – here’s what a CX POST looks like when viewed from SP B.


Note that the chassis and disk WWN seeds match – this is useful if you’ve moved multiple arrays (during a data centre move, for example) and didn’t take note of the SP and DPE pairings (tsk, tsk). Note also that it’s looking at disks 1 and 3 – these are the boot disks for SP B (SP A uses disks 0 and 2).


Note that you never get to a point where you can login via the serial console – it’s really only used for early diagnostics and monitoring.


EMC – CX Troubleshooting – Part 2

In my previous post I talked about how error codes on a CX POST actually mean something, and can assist in your troubleshooting activities. But what does that stupid alphabet soup mean when you see a CLARiiON boot up?


Turns out all of those crazy letters mean something too, and you can refer to this PDF file I put together to work out at what point the array is failing its tests. Please note that I haven’t verified if these apply to the CX3, CX4 or VNX.
