Parameters
- –? | –h | –help
- Displays a detailed description of this command, including syntax, parameter
descriptions, and examples. If you specify a help option, all other command
options are ignored.
- –quiet
- Turns off confirmation messages for this command.
- –spacereclaim minutes
- Specifies the storage pool-space-reclamation interval, in minutes. You
can specify a value from 0 to 1440. The default is 60. A value of
0 disables storage pool-space reclamation.
- –mstrbuff size
- Specifies the size, in 4-KB pages, of the master metadata server buffer.
You can specify a value from 2048 and 8192. The default is 2048.
Note: The
buffer size can only be increased; it cannot be decreased.
- –subbuff size
- Specifies the size, in 4-KB pages, of the subordinate metadata server
buffer. You can specify a value from 30 000 and 250 000. The default is 200
000.
Restriction: The buffer size can only be increased; it cannot
be decreased.
- –admproc number
- Specifies the maximum limit for administrative processes, including the
number of metadata server commands (from the administrative CLI or SAN File
System console), that can run simultaneously. This limit is independent of
the server workload process limit. A few commands, such as those that change
the state of the cluster, can run on a temporary process even if the limit
is currently exceeded. You can specify a value from 4 to 10. If not specified,
the default value is 4.
Restriction: This limit can only be increased;
it cannot be decreased.
- –serverproc number
- Specifies the maximum limit for the metadata server workload process,
which involves only metadata server workload operations. You can specify a
value from 10 to 50. The default value is 20.
Restriction: This
limit can only be increased; it cannot be decreased.
- –privclient list
- Specifies a list of clients, separated by commas, that are to have root-level
privileges (for example, –privclient saki,mefi,leki). The current list is
replaced with the new list of clients. You can specify from zero to 30 clients;
each client name can be up to 256 characters in length and is case-sensitive.
Restriction: This new list replaces the entire list of current privileged
clients. If there are clients that have root or administrative privileges
and you want to add one more client, you must specify both the current and
new clients in the new list.
To remove all clients with root or administrative
privileges, specify –privclient ""; however, at least one privileged
client is required to create files and directories under the root directory
of filesets.
This command does not verify that the specified client
names are valid because the metadata server does not keep static information
about the clients. It does not keep a list of allowed or possible clients.
It has only a list of clients that it allows privileged access if they present
themselves.
- –rsauser rsa_user
- Specifies the Remote Service Adapter (RSA) user ID that is used to access
information from the engines. The RSA user ID and password must be the same
for all engines that host the cluster of metadata servers. Also, the values
must match those in the RSA system.
Attention: Verify that the
user ID is set to the correct ID. If you set an incorrect RSA user ID, all
RSA features (including all engine commands) become unusable.
- –rsapasswd
- Specifies the password corresponding to the RSA user ID. You will be prompted
to enter the password and then confirm it.
Attention: Verify that
the password is set to the correct password. If you set an incorrect RSA password,
all RSA features (including all engine commands) become unusable.
Prerequisites
You
must have Administrator privileges to use the command.
You must be logged
in to the operating system on the engine that hosts the master metadata server
to run this command.
Description
Restriction: If you modify any disruptive settings using
the chadvclusterconfig command, you cannot modify
any cluster settings using the chclusterconfig command until you restart
the cluster.
Example
Changes the cluster settings The following
example changes the subordinate metadata server buffer size to 250 000 and
changes RSA password for the cluster:
sfscli> chclusterconfig -subbuff 250000 -rsapasswd
Are you sure you want to change cluster configuration settings? [y/n] Y
Enter new RSA password:
Confirm new RSA password:
The cluster was modified successfully.
