ESS Installation
112 Avaya Enterprise Survivable Servers (ESS) Users Guide
Note:
Note: In ESS terminology, there is a SID and a Server ID (SVID). The SID is assigned
by RFA and cannot be changed. The Server ID (SVID) is a number selected by
the administrator that is assigned to the server when the server is configured. For
more information on administering the SVID see, Configuring the Servers
on
page 116.
Serial numbers
RFA requires a unique serial number for each license file. In an ESS environment, the serial
number for the reference Internet Protocol Server Interface (IPSI) is used. Each ESS server
requires its own license file with an associated unique IPSI serial number. This implies that
there cannot be more ESS servers than there are IPSI boards in the system. However, for high
availability systems, that have duplex IPSIs, both IPSIs in a Port Network may be used to
generate license files.
IPSI maintenance replacement
As stated earlier, each server in an ESS configuration must contain a license file with a unique
IPSI serial number. When multiple IPSIs in a configuration are being used as reference IPSIs,
additional care is needed when replacing an IPSI for maintenance.
Note:
Note: For each server, you can determine which IPSI serial number is being as a
reference IPSI by clicking License File under the Security heading of the
server’s Maintenance Web Interface.
If a reference IPSI is changed out, a new RFA license file must be generated using the RFA
Swap-Out functionality.
Table 12: RFA naming convention
RFA Name ESS Name Notes
Module ID (MID) Cluster ID (CLID) This value is generated by RFA and is
unique for each ESS server and Main
server.
System ID (SID) System ID (SID) This value is generated by RFA and will
be the same for the Main server and
each ESS server.
