Applies to:Solaris Operating System - Version 11.2 to 11.3 [Release 11.0]
Solaris Operating System - Version 10 1/13 U11 and later
Information in this document applies to any platform.
When mpgroup is configured on Oracle VM Server for SPARC (or LDOMS), failover happens if the primary IO service domain does not process IO requests from a guest domain. If the the primary IO service domain temporary hangs up and eventually recover after the service has already mpgroup failovered to the secondary IO service domain, data corruption on the guest domain can happen.
This issue happens when the guest domain is running with the following releases:
- Solaris 10 with patch 150400-15 or later
- Solaris 11.2 with SRU 1.5 or later
- Solaris 11.3 without SRU 11.6
