When starting ASM instance, it cannot read asm spfile from diskgroup.

Error message in ASM alert log is:

gpnp profile has the correct spfile and asm understands which is the spfile but cannot read it.

Parameters specified in spfile are not in effect. Also ASM instances runs without spfile

ASM diskgroups have sector size 512 bytes.

Recreating spfile on other diskgroups does not help either. However creating spfile on non ASM location works and spfile is recognized.
