Symptoms

Communication between devices in a high availability (HA) configuration might occasionally fail on VIPRION 2200 and 2400 platforms.

Impact

Periodic reported failures in host-to-host communication. This could affect config sync, and other HA related communication.

Conditions

VIPRION 2200 and 2400 platforms with more than one blade. Multiple devices in an HA configuration. TMM incorrectly identifies which TMM should handle host connections from an HA peer. The host connection will be reset after the SYN retransmits are exceeded between TMM and the host process.

Workaround

None.

Fix Information

Host communication on VIPRION 2200 and 2400 platforms behaves the same as host communication on non-VIPRION 2200 and 2400 platforms, as expected.
