I had been assigned to gracefully shut down our CX4-480 SAN; however, in order for me to accomplish this I'd have to password reset it to get in, and be able to assess what we have on it and then shut it down.
I have, before this post, attempted to do the reset by press/release of the reset button from the back of either storage processor, but no luck there. All that did was temporarily off-line the SP with no changes.
My understanding is that there is a means to gain access by serial cable, but if I was looking at the port correctly (wrench icon), that specific cable is AWOL.
I have provided the links below in order to show what I have found to this point, but had not helped any.
If anybody in the audience has any good suggestions or steps I may well have missed, I'm certainly receptive to them.
Thank you for your time.
Thank you for that link, but unfortunately it doesn’t pull up for me (something about not being authorized to view content). Because of this, I would be unable to verify your last question.
I was also provided by our corp IT department with a set of instructions that addressed the password reset. It involved pushing in the reset (two arrows point towards each other). Unfortunately, aside from temporarily taking the device offline, this process also failed.
The button you pushed is called the "NMI Reset" button - this resets the SP - it caused a panic mode to produce a dump for anaalysis. It does not reset the password.
The link was to an article that explains how to reset the password using the Service Port COM1 connection. This is the body of the article:
|Follow these steps to recover the password on the CLARiiON and VNX array. You'll need to connect a PC to the Service Port COM1 on the SP - there is one port on each SP Management Module. Use a null modem cable.|
