Thanks, In situation that path 1 is primary, path 2 is alternate, when path 1 failed, traffic migrates to path 2. Now we can think that path 2 is primary, but there is no alternate path.
Is there a way (not limited to cm) to know that path 1 is back again and reload it as the new alternate path ? If path 1 is down, we can not set it as alternate path, right ? If we can not bring a path back on fly, the usage of APM is limited. --CQ -----Original Message----- From: Sean Hefty [mailto:[EMAIL PROTECTED] Sent: Wednesday, October 25, 2006 11:41 AM To: Tang, Changqing Cc: [EMAIL PROTECTED]; Venkatesh Babu; openib-general@openib.org Subject: Re: [openib-general] APM support in openib stack > How do you know that the old path is back ?

It records the original path used when sending the REQ and uses that same path for all future messages. - Sean _______________________________________________ openib-general mailing list openib-general@openib.org http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
