I recently had an AIX system where the IBM License Management Tool failed to install. The failure message I got is:
CODAG076E Writing the agent signature file to the agent installation folder has failed. Check the agent installation folder and ensure that: -You have write access to the folder. -Files are unlocked. -There is sufficient space on the disk.
CODAG011E - The command cannot be executed.
Of course, installp takes care of everything by removing the evidence. So, the usual install logs get wiped, if they were ever created. I started by checking the likely suspects, /var and /tmp. Both had plenty of free space and both had good permissions. I double-checked my response file, it looked good and has worked on other systems.
So, I turned to filesystem free space. All of my filesytems have plenty of free space, as a percentage of size. And, there aren’t any filesystem full messages in the errpt. But, /opt and / both didn’t have much free space in terms of actual bytes. After adding just a little space to both of those, the install went through normally. And, on another system adding some free space to /var resolved the same error.
