Rescan Physical Disks In OVM Server Crashes Other Servers On Same Chassis (Doc ID 2301827.1)

Last updated on NOVEMBER 02, 2017

Applies to:

Oracle VM - Version 3.4.1 to 3.4.3 [Release OVM34]
Linux x86-64

Symptoms

There are 5 Dell PowerEdge M830 servers have been deployed on same chassis.

Two Dell servers are running Oracle VM server(dom0), other three Dell serves are running Oracle Database on Oracle Linux 6.

All servers are connected to same external storage (EMC Extream IO cluster), but there is no shared LUN between Oracle VM servers and Database servers. 

When presenting some new LUN to Oracle VM servers, we need rescan physical disks from OVM Manager GUI to recognize the new LUN, but the rescan operation crashed the Database servers.

System log from Database severs shows error of "multipath: Failing path".
