We have a Clarion CX4-480 with 2 Disk Shelves. Not able to access it.
We had a previous Ip address configured . Tried multiple ways using serial Console Back to Back network , Navisphere but not able to access.
Can anyone suggest how to do a hard reset or How best we can access it.
First you should verify that the array is booting up correctly. For the CX4 there are the lights (Power and Fault) on the back of the array and the sequence that is displayed when booting up:
If you don't get this then you have problems with the SP's.
The second image does not look like a CX4-480 - this is what the back of the CX4-480 looks like. The first image appears to the the front of a CX4-480 (those would be the power supplies). The part numbers in the second image are not EMC part numbers. Are you sure that the second image is the CX4-480?
Also, there is no "reset" on the CX arrays. If the software image is corrupted, the only solution is to "re-image" the Storage Processors (SP's). This is a task for support personnel and not something that can be done in the forums. You need to find the CX4-480 and the attached BBU that supplies the power to the SP's. As I mentioned in the last post, power off the CX4-480, then power on and watch the Power/Fault LEDs - they should cycle through a series a steps indicated by the frequency of flashes.
On the back of a CX4-480 you can find the PSN - this will have the unit serial number and part number.
Thanks for the update, yes second image is the CX4-480, kindly find the full image of CX4-480 back side. Need your inputs on how to go ahead now with reimage of the SP’s.
First, did you verify the sequence of lights on the back when the array is booting up? That will tell you what needs to be done to get your array back up. My first post explained what to look for when the array is booting. Check the lights and see if it follows the sequence. Where it stops will provide information necessary to determine what the next steps are. In your last image (which is upside down) I can not determine what the state of the LEDs for SPA and SPB are - the light is over saturated. You need to provide either a description of the Power and Fault LEDs or a better image which shows to colors.
I would recommend that you try powering on the array again and note that the sequence of lights are or each SP.
This is the sequence for the Power and Fault lites:
Re-imaging the Storage Processors is a support only function - you'll need to contact your local EMC representative. The process is too complicated and contains proprietary information that can not be discussed on a public forum.
If you are really in doubt about the IP addresses. Then, I would suggest connecting to service LAN port with IP 184.108.40.206 for SPA or 128.221.251 for SPB, subnet mask = 255.255.255.192.
You may set your laptop IP to:
- from the browser in your laptop:
Enter your login information, Then you can see the SPs IP addresses.
