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

 

You can view Blacklist (Prism Element) as follows and cleanup:

 

#logon to PE CVM
# retrieve blacklist ("Nodata" -> means a site is blacklisted)
zkcat /appliance/physical/blacklisted | strings

 

# clear blacklist
zkrm /appliance/physical/blacklisted

 

# retrieve blacklist (Zookeeper error: no node. means nothing blacklisted)
zkcat /appliance/physical/blacklisted | strings

You can view Blacklist (Prism Central) as follows and cleanup:

#logon to PC

zkcat /appliance/physical/blacklist

#Sample Output:

{

  "clusterUuid" : "xxxxxxxx-xxxx-xxxx-xxxx-000000012345",

  "clusterIncarnationID" : 123456789012345,

  "unregistrationCause" : "AOS_DECOMMISION"

}

#Check in PE Cluster Settings if UUid is "xxxxxxxx-xxxx-xxxx-xxxx-000000012345"

#if so cleanup with 

zkrm /appliance/physical/blacklist

#and check again:

zkcat /appliance/physical/blacklist

#Zookeeper error: no node. means nothing blacklisted.

Try again, registration should work now!

Be sure, you removed the clusters correctly and performed the cleanup!
