The target can be one or more of the following:

conf Specifies that the /etc/modprobe.conf or /etc/modules.conf file is

to be updated. The command configures the options lnet settings for all

interconnects that can be used to access the file systems served by the

identified or specified servers. You can later edit the /etc/

modprobe.conf or /etc/modules.conf file to restrict the interfaces

that can be used for mounting file systems.

tab Specifies that the /etc/sfstab and the /etc/sfstab.proto files are to

be updated.

hosts Specifies that the /etc/hosts file is to be updated. The command adds an

entry for each HP SFS system that will be accessed.

all Specifies that all of the above targets are to be updated.

If no /etc/sfstab or /etc/sfstab.proto file exists on the client node, you must use the

-s|--server name option to specify an HP SFS server that needs to be accessed.

The sfsconfig command performs the following actions:

• Enumerates the interconnects on the client node.

• Checks if the modprobe.conf.lustre or modules.conf.lustre file exists.

• Checks for the necessary option lnet entry in the modprobe.conf.lustre or

modules.conf.lustre file.

• Lists the changes that are proposed.

• Backs up the old file.

• Adds the necessary entries to the configuration files.

If the /etc/sfstab and the /etc/sfstab.proto files are specified as targets (by specifying the conf

or all targets), the sfsconfig command converts the existing entries as follows:

• Converts any mount directives that use the ldap protocol to the http: protocol (unless the

-L|--keepldap option is specified).

• Comments out mount directives that use the http: protocol and adds equivalent directives using the

lnet: protocol (unless the -H|--keephttp option is specified).

If the command encounters problems when upgrading the files, it reports the reason for the problems. For

example, if any of the interconnects specified in the /etc/sfstab or /etc/sfstab.proto files do not

exist on the client node, the

sfsconfig command reports the problem.

Examples

To add the appropriate options lnet settings and lquota entries to the /etc/modprobe.conf or

/etc/modules.conf file, enter the following command:

# sfsconfig conf

To convert the mount directives in the /etc/sfstab and /etc/sfstab.proto files to the lnet:

protocol, enter the following command:

# sfsconfig tab

The following command adds the appropriate options lnet settings and lquota entries to the

/etc/modprobe.conf or /etc/.modulesconf file and converts the mount directives in the

/etc/sfstab and /etc/sfstab.proto files to the lnet: protocol:

# sfsconfig all

To update the existing lnet: mount directives in the /etc/sfstab and /etc/sfstab.proto files

while keeping the existing ldap: and http: mount directives, enter the following command:

# sfsconfig -H -L tab
