bring up a VM TCPIP stack on a different set of devices on your backup OSA (Define the real addresses in the directory or SYSTEM DTCPARMS) try something like FB04-6, configure it as OSD/QDIOETHERNET, and just have it sit there doing "nothing". You could disable its telnet server, too, perhaps to keep security folks happy.
This way the OSA MAC address will be known to the physical switch. In other words bring up a stack machine on the backup OSA that is not a member of the VSWITCH. David -----Original Message----- From: Linux on 390 Port on behalf of Levy, Alan Sent: Tue 4/4/2006 1:50 PM To: [email protected] Subject: OSA question We have a vswitch defined here as follows: VSWITCH SYSTEM VSW1 Type: VSWITCH Connected: 3 Maxconn: INFINITE PERSISTENT RESTRICTED NONROUTER Accounting: OFF VLAN Unaware State: Ready IPTimeout: 5 QueueStorage: 8 Portname: UNASSIGNED RDEV: FA00 Controller: DTCVSW2 VDEV: FA00 Portname: UNASSIGNED RDEV: FB00 Controller: DTCVSW1 VDEV: FB00 BACKUP This vswitch was defined over 1 year ago and at that time failover was tested successfully. This works great and worked great until this past Sunday. Our network group was doing maintenance and brought down the primary osa FA00. The switch did not fail over to the FB00 osa. They had to back out their changes. We found out this week that sometime in the past year, one of the cables to the FB osa became unplugged (there are no other servers connected to that switch). Our network group actively checks the LAYER-2 (MAC) addresses display on the Cisco switches where the OSA connections are plugged. They only see the MAC address of the primary interface on the VSWITCH. The backup VSWITCH port does not show a MAC address on the Cisco switch. They would like to actively monitor both interfaces so that if a real problem occurs on the backup interface, it can be detected PRIOR to a VSWITCH failover. Since they currently can't monitor those connections they never noticed it had a problem. Then when we really needed the backup it wasn't there and we experienced an outage. Is there a way to have both the primary and backup OSA interfaces show a MAC address on the Cisco switches? ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
