[SRX/J] Can the secondary node of a chassis cluster be managed via J-Web?

J-Web management can be performed only on the primary node for the 0 redundancy group.

The reason is that daemons referenced by J-Web are not running on the secondary node.

Example

The following example shows output of syslog and system process on both node0 and node1 after RG0 was failed over from node1 to node0.

On node1, web-management daemon (httpd-gk) was terminated (exited).
On node0, web-management daemon (httpd-gk) was started.
Two http related daemons; httpd-gk and httpd, run only on node0, which is the new primary node of RG0.

{primary:node0}
root@SRX210HE-A> show system processes extensive node 1 | grep http    
  => No httpd-gk and httpd processes running on node 1 (secondary node)

This limits remote procedure calls (RPCs) from J-Web logic and, subsequently, pages that can be issued from the secondary node. Therefore, J-Web management of the secondary node is not allowed.
