In my company, it's fallen on me to serve as the admin of our new HPC cluster, a task that's very new to me. It's very important to me to lay a solid foundation and avoid any unnecessary pitfalls. So, can anyone recommend a succinct guide or list of do's-and-don'ts for adiminstering an HPC cluster? The cluster runs the latest CentOS, PGI compilers, MPICH2, WRF, etc.
A recent post where someone suggested redirecting with a clobber ">" to a file the same command was reading from prompted me to post this sysad good practice list. Some items are from times where I have learned things the hard way. I think this would be helpful so we can learn from each others... (8 Replies)

cmdeleteconf(1m)cmdeleteconf(1m)NAME
cmdeleteconf - Delete either the cluster or the package configuration
SYNOPSIS
cmdeleteconf [-f] [-v] [-c cluster_name] [[-p package_name]...]
DESCRIPTION
cmdeleteconf deletes either the entire cluster configuration, including all its packages, or only the specified package configuration. If
neither cluster_name nor package_name is specified, cmdeleteconf will delete the local cluster's configuration and all its packages. If
the local node's cluster configuration is outdated, cmdeleteconf without any argument will only delete the local node's configuration. If
only the package_name is specified, the configuration of package_name in the local cluster is deleted. If both cluster_name and pack-
age_name are specified, the package must be configured in the cluster_name, and only the package package_name will be deleted. cmdelete-
conf with only cluster_name specified will delete the entire cluster configuration on all the nodes in the cluster, regardless of the con-
figuration version. The local cluster is the cluster that the node running the cmdeleteconf command belongs to.
Only a superuser, whose effective user ID is zero (see id(1) and su(1)), can delete the configuration.
To delete the cluster configuration, halt the cluster first. To delete a package configuration you must halt the package first, but you do
not need to halt the cluster (it may remain up or be brought down). To delete the package VxVM-CVM-pkg (HP-UX only), you must first delete
all packages with STORAGE_GROUP defined.
While deleting the cluster, if any of the cluster nodes are powered down, the user can choose to continue deleting the configuration. In
this case, the cluster configuration on the down node will remain in place and, therefore, be out of sync with the rest of the cluster. If
the powered-down node ever comes up, the user should execute the cmdeleteconf command with no argument on that node to clean up the config-
uration before doing any other Serviceguard command.
Options
cmdeleteconf supports the following options:
-f Force the deletion of either the cluster configuration or the package configuration.
-v Verbose output will be displayed.
-c cluster_name
Name of the cluster to delete. The cluster must be halted already, if intending to delete the cluster.
-p package_name
Name of an existing package to delete from the cluster. The package must be halted already. There should not be any
packages in the cluster with STORAGE_GROUP defined before having a package_name of VxVM-CVM-pkg (HP-UX only).
RETURN VALUE
Upon completion, cmdeleteconf returns one of the following values:
0 Successful completion.
1 Command failed.
EXAMPLES
The high availability environment contains the cluster, clusterA , and a package, pkg1.
To delete package pkg1 in clusterA, do the following:
cmdeleteconf -f -c clusterA -p pkg1
To delete the cluster clusterA and all its packages, do the following:
cmdeleteconf -f -c clusterA
