If you want to know about disk usage of your HMC.
lshmcfs command can help you to find out size of temporary objects on your HMC, with this parameters you will list only selection of several values :
lshmcfs -F filesystem filesystem_size filesystem_avail temp_files_size --header
filesystem filesystem_size filesystem_avail temp_files_size
/var 5983 4518 202
/var/hsc/log 7999 1663 5298
/dump 250958 238070 0
/extra 20030 15945 0
/data 302250 278244 2134
/ 15998 8579 0All size and free space values displayed by this command are in megabytes.
/var contains HMC trace and log files
/dump system dumps, frame dumps, debug data by pedbg command
/extra system dumps, frame dumps
/ java core dumps, heap dumps, HMC trace files
this parameters will show you how much space can be freed if all temporary files older than 20 days :
lshmcfs -o c -d 20 -F filesystem filesystem_size filesystem_avail temp_files_size to_be_freed --header
filesystem filesystem_size filesystem_avail temp_files_size to_be_freed
/var 5983 4557 162 39
/var/hsc/log 7999 5457 1497 3816
/dump 250958 238070 0 0
/extra 20030 15945 0 0
/data 302250 280378 0 2134
/ 15998 8579 0 0with chhmcfs command you can actually run cleanup (only temporary files older than 20 days and only in /var/hsc/log) :
chhmcfs -o f -d 20 -f /var/hsc/log
you can also filesystem disk space usage with monhmc command
monhmc -r disk -n 0
