|Configure Eucalyptus Storage / Configure Block Storage|
This topic describes the initial state of the Storage Controller (SC) after you have registered it with the Cloud Controller (CLC).
The SC automatically goes to the broken state after being registered with the CLC; it will remain in that state until you explicitly configure the SC by telling it which backend storage provider to use.
You can check the state of a storage controller by running euserv-describe-services --expert and note the state and status message of the SC(s). The output for an unconfigured SC looks something like this:
SERVICE storage ZONE1 SC71 BROKEN 37 http://192.168.51.71:8773/services/Storage arn:euca:eucalyptus:ZONE1:storage:SC71/ SERVICEEVENT 6c1f7a0a-21c9-496c-bb79-23ddd5749222 arn:euca:eucalyptus:ZONE1:storage:SC71/ SERVICEEVENT 6c1f7a0a-21c9-496c-bb79-23ddd5749222 ERROR SERVICEEVENT 6c1f7a0a-21c9-496c-bb79-23ddd5749222 Sun Nov 18 22:11:13 PST 2012 SERVICEEVENT 6c1f7a0a-21c9-496c-bb79-23ddd5749222 SC blockstorageamanger not configured. Found empty or unset manager(unset). Legal values are: das,overlay,ceph
Note the error above: SC blockstoragemanager not configured. Found empty or unset manager(unset). Legal values are: das,overlay,ceph.
This indicates that the SC is not yet configured. It can be configured by setting the ZONE.storage.blockstoragemanager property to 'das', 'overlay', or 'ceph'.
If you have installed the (paid) Eucalyptus Enterprise packages for your EBS adapter, you will also see additional options in the output line above, and can set the block storage manager to 'netapp', 'equallogic', or 'threepar' as appropriate.
