DBCA 10.2.0.1 -11.1.0.7 when viewing ASM candidate devices
Symptoms
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.
Changes
Enabling visibility of the /dev/rdsk/c?t?d?p0 device by changing the permissions on the Solaris device
it points to.
