House Keeping in HMC

This section shows how to handle filesystem "/var" utilization in an HMC. Since the /var filesystem holds all the log files, performing periodic house keeping on /var would keep it in a consistent state.

Login into HMC-CLI.

1) # monhmc -r {disk|proc|swap|mem} -n #

-r :  Resource
-n : Interval to repeat the status of the resources.

2) # chhmcfs -o f { -d days | -h hours| -s size} -f filesystem

-o : Operation to be performed, "f" refers to free the filesytem.

# chhmcfs -o f -d 3

The above command cleans up the log files from all the filesystem except the last 3 days -d 3.

# chhmc -o f /var

The above command cleans up all the log files in tehe /var filesystem.

3) # monhmc -r disk

Verify the filesystem size after performing the operation.
