Note
Master and Slave are legacy terms that carry connotations that are not enforced by the ISS
protocol. Please keep their restricted meanings, as described above, in mind while studying this
section.
The ISS feature can be used in different ways depending on the needs of the organization. There are
ISS configurations where two Satellites may act as both masters and slaves of each other. T his section
contains a section on use cases, and how best to set up ISS to suit your organization.
ISS Requirements
The following are the required conditions to be able to use ISS:
Two or more Red Hat Satellite servers
At least one Red Hat Satellite populated with at least one channel
Satellite Administrator privileges on all Satellite systems intended for ISS
1.3.1. Inter-Satellite Synchronization
ISS can be configured manually or by a new tool called spacewalk-sync-setup. Both methods are
effective, and it would be left to the user's choice on which one to use.
1.3.1.1. Manual Configuration
Procedure 1.1. Configuring the Mast er Satellit e Server
With Satellite 5.6, ISS allows the Slave Satellite to duplicate the organizational trust hierarchy and the
custom channel permissions from the settings configured on the master. T his is accomplished by
exporting information about specific organizations from the Master Satellite to the receiving Slave
Satellite. The Satellite Administrator on the Slave Satellite can then choose to map the Master
Organizations to specific Slave Organizations. Future satellite-sync operations use this information
to assign custom channel ownership to the Slave Organization which is mapped to a specific Master
Organization. It can also map the trust relationships between the exposed Master Organization to
matching Slave Organizations, creating the equivalent relationships on the Slave.
1. On the Web Interface:
a. Log in as the Satellite Administrator.
b. Click Admin → ISS Configuration → Mast er Setup.
c. On the top right-hand corner, click Add New Slave.
d. Fill in the following information:
Slave Fully Qualified Domain Name (FQDN)
Allow Slave to Sync? - Choosing this field will allow the Slave Satellite to access this
Master Satellite. Otherwise, contact with this Slave will be denied.
Sync all orgs to Slave? - Checking this field will synchronize all organizations to the
Slave Satellite.
