The Problem

During 12.2.0.1 GI install on AIX 7.1, at OUI screen “create ASM disks”, asm disks are not discovered by kfod. It is failing with the following error in gridSetupActions.log:

The Solution

I/O Completion Ports(IOCP) parameter value was set to Defined. The following sample output shows the IOCP status is set to Defined:

$ lsdev | grep iocp
iocp0 Defined I/O Completion Ports

Here you need to change the IOCP IBM AIX parameter from “defined” to “available”, this action requires root privilege.

You can use following steps to modify IOCP attribute to Available:

1. Log in as root and run the following command:

# smitty iocp
Select Change / Show Characteristics of I/O Completion Ports.
Change configured state at system restart from Defined to Available.

2. Reboot server.

3. Run the lsdev command to confirm the IOCP status is set to Available:

$ lsdev | grep iocp
iocp0 Available I/O Completion Ports

Note:By default, IOCP is set to “Defined”. On IBM AIX on POWER Systems (64-Bit) and need to set I/O completion ports (IOCP) to “available” to ensure successful database and grid infrastructure installation.
