Information in this document applies to any platform.


During install of Grid Infrastructure software, Oracle Universal Installer (OUI) displays no disks at all under STORAGE OPTION > CREATE ASM DISK GROUP.

Note: See attached screen shot

* ASMLIB ('oracleasm listdisks', either from /usr/sbin or /etc/init.d directories) across all nodes, shows all ASM disks.
* Also kfod ('asm_diskstring=/dev/oracleasm/disks/* disks=all' or 'asm_diskstring=ORCL:* disks=all', or 'disks=all'), does show all the ASM disks
* Checked that no ORA* or TNS* OS environments set for the session that launched the runInstaller.
* OS owner and file permissions on these asmlib devices seem proper (oracle:dba and 660).
* The asmlib devices using emcpower multipath devices. From the contents of /etc/sysconfig/oracleasm, appears these are properly configured.
