Description
With corresponding parameters, the dms command sets default directories, timeout values, level of logging, security method used, Kerberos keytab path, Kerberos principal, and communication ports on a data server within an NDAF domain.
Parameters
The dms command takes one or more of the following optional parameter values:
Item | Description |
---|---|
[-rpc_timeout=val] | Sets the timeout for an RPC connect or call. Default is 300 seconds. |
[-log_level=val] | Sets the level of logging for the log files.
The default is notice. Possible values include the following
values:
|
[-security=val] | Sets the type of security method used. The default
is krb5 . Values include:
|
[-krb5_principal=val] | Sets the Kerberos principal used for the kinit. |
[-serv_port=val] | Sets the dms port waiting for the dmadm RPC. Default value is 28001. |
[-serv_serv_port=val] | Sets the dms port waiting for the other dms RPC. Default value is 28003. |
[-ndaf_dir=val] | Sets the base directory for NDAF. It contains
default databases, logs, and directories for cells, dsets, and replicas.
The default for the base directory is /var/dmf.
Other defaults include the following directories:
Note: At least either the -ndaf_dataset_default and -ndaf_replica_default parameters,
or the -ndaf_dir parameter have to be specified.
The creation of cells, data sets, and replicas must have been enabled,
by using the dms_enable_fs command, on the
file systems that contain the specified directories to store the data
sets and replicas.
|
[-ndaf_dataset_default=val] | Sets the default directory for dsets. Note: At
least either the -ndaf_dataset_default and -ndaf_replica_default parameters,
or the -ndaf_dir parameter have to be specified.
The creation of cells, data sets, and replicas must have been enabled,
by using the dms_enable_fs command, on the
file systems that contain the specified directories to store the data
sets and replicas.
|
[-ndaf_replica_default=val] | Sets the default directory for replicas. Note: At
least either the -ndaf_dataset_default and -ndaf_replica_default parameters,
or the -ndaf_dir parameter have to be specified.
The creation of cells, data sets, and replicas must have been enabled,
by using the dms_enable_fs command, on the
file systems that contain the specified directories to store the data
sets and replicas.
|
[-ndaf_log_dir=val] | Sets the directory for log files. It is set to ${ndaf_dir}/log by default. |
[-krb5_keytab=val] | Indicates the Kerberos keytab path. If you do not specify the parameter and the system resource controller (SRC) is not in use, the keytab is defined either by the KRB5_KTNAME environment variable, or by the default as specified in the /etc/krb5/krb5.conf file (when the KRB5_KTNAME variable is not set). If you do not specify the parameter but the SRC is in use, the keytab is always the default as specified in the /etc/krb5/krb5.conf file. |
[-admin_cb_port=val] | Sets the dmadm port
waiting for the dms RPC callbacks. The default
is 28002 . |

Examples
- To start the dms command using SRC and
specifying the /ndaf_fs directory for NDAF files, enter:

- To start the dms command using SRC and
specifying the /ndaf_fs directory for NDAF files and a security
value of auth_sys, enter:
