- change: Filesystem mode changed from JFS2 to JFS
- cause: Asynchronous I/O has not been configured or started on the system.
fix: Make Asynchronous I/O available on system, following the next steps to set it up: 1. Log in as root 2. Type: mkdev -l aio0 This command attempts to verify that Asynchronous I/O services are running (available on system), if not, they are started. 3. To ensure it is configured at each system restart : a. Type: smit aio b. Select the menu item "Change/Show Characteristics of Asynchronous I/O" c. Change the field "STATE to be configured at system restart" from DEFINED to AVAILABLE. or just execute the next command and it will do the same as the previous a, b and c steps: chdev -l aio0 -a autoconfig='available' which should return the message "aio0 changed". Step 3 (either of the two ways) will toggle the state to be configured at system restart to be available, making asynchronous I/O available with each system reboot.
