If the following system connection or component fails to respond to network communication:
•
The control connection between a K2 SAN-attached system and GigE switch “A”.
Then the following failover behavior occurs:
1. The control team on the K2 SAN-attached system fails over and communication begins on the
other control port.
2. The control communication finds a path through GigE “B” switch and across an ISL to GigE
switch “A” to reach the same control port on the same K2 Media Server.
3. Media (iSCSI) traffic keeps using the same path.
4. K2 Media Server “A” is still the media file system/metadata server. The media file system (SNFS)
and media database do not fail over.
5. The other K2 SAN-attached systems (not affected by the connection failure) keep using the same
paths for media and control, as in pre-failover behavior.
