Hello R.Hari,

You are going to need to open a support case to resolve this issue.

Hello R.Hari,

As long as you remove the cluster as stated you will not lose any data.

Hello R.Hari,

To resolve that error there are some commands that support has to run.  I understand that your system is out of support, but the commands to resolve this is limited to support only.

Hi,

Are you able to reboot the devices and see if it can reconnect? This article may also help. https://dell.to/3B8QLE5

Let us know if you have any further questions.

Thanks . All cluster operations are returning error "invalid_in_cur_sys_state". So I did try emergency shutdown and start up procedure. Did not help.

Thanks. Will do. One thing I wanted to try was to remove and re-add cluster to XMS to see if it fix cluster status issue

#Show-Clusters

Cluster-Name Index State Gates-Open Conn-State
CLU01 1 unknown True connected

remove-cluster and add-cluster operations wont wipe data right? I read it wont, but just wanted to be 100% sure. 

It was removed from cluster and now wont let me add back. I am getting below error.

xmcli (admin)> add-cluster sc-mgr-host="1XX.XX.XX.232" force
09:04:11 - Collecting cluster information

Also I looked up Dell EMC portal with Serial number. This device is not under support. 

It was an X Prod unit we re-purposed for Lab. With that I am not sure if it can be recovered / re-used. 

Hi Sam,

Thanks and I understand.

But as you know, there are almost 0 documents / articles out for for for systems like XIO. All that one could find is the user guide in Dell EMC portal. While I am sure Dell EMC cant help, I decided post it  here in the community hoping someone previously experienced the issue could advise. 

I spent some time over the last two week on it, as it's still the heart of our VMware lab and we wouldn't want to just throw it away. No luck yet. Let me know if anyone got any ideas. Cheers. 

FYI, we got the same exact error trying to import a previously running XIO cluster into an XMS.  The issue turned out to be that not all components (e.g., DAEs, controllers, back-end IB switches) were powered on.  Once we got everything plugged in/powered on, the add-cluster command succeeded. 

Our cluster had been removed from the XMS and powered down in preparation for decommissioning, but it was decided they wanted to repurpose it.  So not exact use case as above, but similar (with the addition of it being powered off).

Just wanted to leave this here in case someone runs into this same error message.
