Last updated on MARCH 08, 2017
Applies to:Oracle Server - Enterprise Edition - Version: 10.2.0.1 to 188.8.131.52
Sun Solaris x86-64 (64-bit)
DBCA 10.2.0.1 -184.108.40.206 when viewing ASM candidate devices
On Solaris x86-64 it is possible to present to ASM p-partitions, i.e. partitions named
/dev/rdsk/c?t?d?p?, also known as fdisk or PC BIOS partitions.
However the device size showed by ASM is wrong. I.e. it doesn't match the physical device or disk size.
For example in case of c?t?d?p0 it would be assumed ASM would see the whole disk but a wrong size is showed by DBCA.
it points to.
Consider a p0 device like:
ls -l /dev/rdsk/c0t3d0p0 lrwxrwxrwx 1 root root 77 Jul 14 2006 /dev/rdsk/c0t3d0p0
and by issuing
chown oracle:dba /devices/pci@0,0/pci8086,3595@2/pci8086,330@0/pci1028,16d@5/sd@3,0:q,raw
the device would become visible to ASM.
