Symptoms

When installing 11.2.0.3 Grid Infrastructure on AIX 6.1 TL07, root.sh succeeds on first node but fails on the second node:
[UsmcaLogger.logException:175]  oracle.sysman.assistants.util.sqlEngine.SQLFatalErrorException: ORA-15018: diskgroup cannot be created
ORA-15031: disk specification '/dev/rhdiskpower0' matches no disks

Here /dev/rhdiskpower0 does not show in kfod output on second node. It is an EMC multipath pseudo disk device.

But the disk can be found with AIX command.
