#271519: Solaris 10 Kernel Patches 141444-09 and 141445-09 May Cause Interface Failure in IP Multipathing (IPMP)

Category : Availability
Release Phase : Resolved
Bug Id : 6888928
Product : Solaris 10 Operating System
Date of Workaround Release : 03-Nov-2009
Date of Resolved Release : 10-Dec-2009

Solaris 10 Kernel Patches 141444-09 and 141445-09 cause interface failure in IP Multipathing:



1. Impact

The IP Multipathing (IPMP) facility allows systems with multiple network interfaces in the same subnet to failover in the event that one of the interfaces fails, and then failback when the interface is ok.

Solaris 10 Kernel Patches 141444-09 (SPARC) and 141445-09 (x86) cause interface failure in IPMP when configured for probe based failure detection. This issue does not occur with a IPMP link based failure detection configuration.

2. Contributing Factors

This issue can occur in the following releases:

SPARC Platform:

* Solaris 10 with patch 141444-09 and without patch 142900-02

x86 Platform:

* Solaris 10 with patch 141445-09 and without patch 142901-02

Note 1: Solaris 8 and 9 and OpenSolaris are not impacted by this issue.

Note 2: This issue only occurs on systems with IPMP configured for probe based failure detection. This issue does not occur with a IPMP link based failure detection configuration.
