Removing all GPFS file systems and configuration

Removing all GPFS file systems and configuration In a test environment, it is often useful to remove all GPFS configuration to the point where it is identical to a fresh install. This is also required if you want to uninstall GFFS. The broad procedure is as follows: Unmount all the file systems with umount . It is easiest to do this using the dsh command. If you have multiple file systems, you must umount all of them. Delete all file systems with mmdelfs . Again, you must run the mmdelfs command once for each file system but it, like all the remaining commands in this process, need only be run on the GPFS primary node. Delete all NSDs with mmdelnsd . You will most certainly have multiple NSDs. Each one must be deleted using the mmdelnsd command. Shutdown GPFS on all nodes with mmshutdown -a . If you have multiple nodesets, you must run the mmshutdown -a command for each nodeset as follows: # mmshutdown -C <nodeset> -a Remove all nodes from nodeset with m...

HMC event to Syslog

Using syslogd on AIX to have HMC events logged Question How can I get alerted to HMC console events on my AIX system? Answer You can enable the HMC to send console events to a remote server on your network by using syslogd. On the HMC, enable syslogd and give it the hostname of the remote server. You can do this from the HMC restricted shell window or via ssh: # chhmc –c syslog –s add –h remotehost.domain.com On the AIX remote server, the syslogd daemon must be running and set up to receive messages over the network. In AIX, the /etc/syslog.conf file should be edited by un-commenting the appropriate lines at the bottom of the file, such as: *.debug /tmp/syslog.out rotate size 100k files 4 Ensure that the output log exists and refresh syslogd: # touch /tmp/syslog.out # refresh –s syslogd The /tmp/syslog.out file will now be updated when a new HMC console event is logged.
