configured cluster name. If the names do not match, no node IP addresses are returned in the
response.
If Scsp-Proxy-Cluster is not present, the request uses the configured cluster name and the list of
node IP addresses reflects the currently known node IPs for that cluster.
In either case, the response metadata includes a response header with the same name containing
the cluster name used by the Proxy.
1.1.1.2. Response Headers
The following table discusses response headers:
Response
Scsp-Proxy-Cluster
Scsp-Proxy-Nodes
Scsp-Proxy-Agent
Castor-System-
TotalGBAvailable, Castor-
System-TotalGBCapacity
For example, the following response indicates there are 10 nodes in the cluster:
Scsp-Proxy-Nodes: count=10
If the response indicates zero nodes in the cluster, it is accompanied by a reason, as follows:
Scsp-Proxy-Nodes: count=0, reason=no-nodes
The following table discusses reason codes.
Reason for empty node list
no-nodes
bad-subnet
bad-cluster

Description
Cluster name (for example, if the cluster is configured on
a CSN, it is the value of scsp.clusterName in /etc/
caringo/scspproxy/scspproxy.cfg).
ASCII string count of the number of node IP addresses
returned in the body of the response. If this count is zero,
an additional reason is supplied to explain why there were
no nodes returned. More information about the zero-node
response is discussed following the table.
Proxy and its software version.
Obtained by polling any available node on the local
cluster. These headers are provided to maintain
consistency with current Proxy and DX Storage
responses.
Meaning
The Proxy reports no nodes when, for example, the cluster is
off-line or is being rebooted.
The request was made from a subnet from which the node IP
addresses are not routable.
The Proxy determines whether or not a request originated from
the same private subnet as its cluster and responds only if the
request did originate in that subnet. The Proxy does this to help
prevent malicious discovery about the cluster and because
private IP addresses are not routable anyway.
The cluster name supplied in the Scsp-Proxy-Cluster
header did not match the currently configured cluster.
