System hang after update to 6100-03

Systems with Encypted File System (EFS) support enabled may fail to boot after updating to the 6100-03 Technology Level.

This problem occurs if the clic.rte.kernext and clic.rte.lib filesets are installed at a

level below 4.6.0.0. EFS may be enabled if the 'efsenable' command was ever executed

on the system, even if there are no encrypted file systems currently in use. The presence of the file /var/efs/efsenabled indicates that EFS is enabled.

To avoid this issue, update the clic.rte.kernext and clic.rte.lib filesets to the 4.6.0.0 level from the clic.rte image available on the AIX Expansion Pack, dated 5/2009 or later. The clic.rte filesets need to be updated before the system is rebooted after updating to the 6100-03 Technology Level.

If the 6100-03 Technology Level is installed without updating the clic.rte filesets to the 4.6.0.0 level, the system may fail to reboot. Should this occur, you can recover using the following procedure.

1. Reboot system into service mode

2. Select 'Task Selection', then chose 'Shell Prompt'

3. Move file /var/efs/efsenabled to /var/efs/efsenabled.SAVE

4. Reboot system into normal mode

5. Update clic.rte.kernext and clic.rte.lib to the 4.6.0.0 level

6. Move back /var/efs/efsenabled from /var/efs/efsenabled.SAVE

Distribution of the 6100-03 Technology Level on Fix Central has been temporarily suspended until this issue is resolved.

So, be warned!
