Unable to register PE in PC due to Blacklist / "The cluster is blacklisted on prism central."

 

When trying to register the PE again to PC, you will encounter the following error:

The cluster is blacklisted on Prism Central

or

The cluster is blacklisted for further registration.

We were informed, that we are not allowed to publish the solution for that, as these are internal informations. So please open a support case at Nutanix or contact us directly :-)

Nutanix Node Expansion Precheck Failed - Failure in pre expand-cluster tests. SSD tier on nodes is not sized to accomodate expected metadata growth on cluster kb-8842

The error is to be expected when existing older clusters with fullflash nodes are expanded with full-NVMe nodes. Typically, the NVMe Models are not listed in the Nutanix HCL file.

The new nodes includes NVMe SSDs witch are not llisted in the cluster HCL-file on the existing CVMs.

ssh to one of the new nodes and run:

list_disks

Example:

check HCL- File on one of the existing CVMs

cat /etc/nutanix/hcl.json

and check if the model is listed. If not, proceed with updating the hcl.json in

cd ~/foundation/lib/foundation-platforms/

backup:
sudo cp /etc/nutanix/hcl.json /etc/nutanix/hcl.json_backup copy the edited file: sudo cp ~/foundation/lib/foundation-platforms/hcl.json /etc/nutanix/hcl.json sudo chmod 644 /etc/nutanix/hcl.json

Restart Genesis:

allssh genesis restart
