Diameter Signaling Router (DSR) : TVOE Host Management Interface (XMI) Is Inaccessible But Guest Servers XMI Is OK

(Doc ID 2364634.1)

Last updated on MARCH 09, 2018

Applies to:

Oracle Communications Diameter Signaling Router (DSR) - Version DSR 7.0.1 and later
Information in this document applies to any platform.

Symptoms

TVOE XMI address is not accessible directly. Guests hosted on TVOE currently carry traffic across the XMI network without impairment.

Changes

No known change may be remembered; TVOE XMI is rarely used so it is possible to go undetected for an indefinite term if the guest traffic remains OK. 

One known trigger may be 'shortcut' server replacement procedure where the disk drives from the failed server are retained and re-used in the replacement server in an attempt to avoid re-building the host and guest application servers (standard method).  This is not a supported server (blade/rack-mount) replacement method but has been known to be used by operators and may be [or may appear to be] sometimes successful.
