Cause



Excerpt from Storage Foundation (SF) 5.0 MP3 Release Notes:

Extensible Firmware Interface support (303294, 834313, Sun Bug ID 6226760)

The Solaris 9 and 10 64-bit kernel Operating Systems provide support for disks larger than 1 terabyte. Disks of this size are formatted with the Extensible Firmware Interface (EFI) disk label rather than the VTOC disk label. EFI formatted
disks are supported with Veritas Volume Manager only on Solaris 10 (SPARC).


Solution



VxVM running on Solaris 9 does not support EFI labeled disks greater than 1TB size.
Solution is to reduce the size of the LUN to less than 1TB and use SMI label instead.
