Mirrored Volume Fails When Using O_EXCL Flag (4820273)

Problem Summary: If Solstice DiskSuite/Solaris Volume Manager is being used and a mirrored volume is opened with O_EXCL flag, the failover of the device group containing this volume will fail. This will panic the new device group primary, when the volume is first accessed after the failover.

Workaround: When using Solstice DiskSuite/Solaris Volume Manager, do not open mirrored volumes with O_EXCL flag.
