Set IOCP Status
While upgrading to Enterprise Manager 13c Release 4 on AIX platform, you must make sure that I/O Completion Port (IOCP) Status is shown as Available.
Run the following command to check the IOCP Status:
/usr/sbin/lsdev -c iocp -F status
If the IOCP Status is not Available, then see Checking I/O Completion Port (IOCP) settings to change the status.
