Configuring a DFS Fileset Location Database

To configure a Fileset Location Database machine, perform the following steps:

1. Type 6 on the Additional Server Configuration menu and press <Return>.

The dce_config script displays the following message:

S:****** Configuring DFS Fileset Location Database Server...

and then prompts:

Enter Cell Administrator's principal name: (cell_admin)

2. Type the name of the principal who was defined to be the initial privileged user of the registry database during the configuration of the master Security server and press <Return>.

The dce_config script prompts:

Enter password:

3. Type the password for the initial privileged user's account and press <Return>. Note that this password is not displayed as you type it.

The dce_config script loads the DFS kernel extensions and displays the following messages:

S:****** Loading kernel extensions...
rpc_config: installed krpc device at major number 71

Then the dce_config script prompts for whether LFS (Episode) should be loaded

Should the LFS Kernel Extension be loaded (n)?

4. Type y to configure the machine to use LFS or n to not and press <Return>.

The dce_config script displays:

Should LFS be initialized (n)?

5. Type y to initialize LFS or n to not and press <Return>.

The dce_config script displays the following messages as it adds the appropriate DFS members to groups in the Security database.

S:****** Modifying the registry database for DFS server operation...

>>> group member added

>>> group member added

Current site is: registry server at /.../test_cell/subsys/dce/sec/master
Domain changed to: group
Current site is: registry server at /.../test_cell/subsys/dce/sec/master
Domain changed to: group
S:****** Starting bosserver...
Checking for a Ubik sync site in hosts/node_name
Host /.:/hostsnode_name / is now the sync site

Then dce_config script prompts:

Enter the name of the system control machine:

6. Type the name of the machine configured as the system control machine and press <Return>. If your cell does not use a system control machine enter the name of the local machine.

The dce_config script prompts:

Enter the fileset name (root.dfs):

7. Type the name of the DFS file set and press <Return>.

The dce_config script prompts:

Enter the filesystem type for root.dfs:
1. Native File System (e.g. UFS, JFS)
2. Episode File System (LFS)
selection:

Your next steps depend on whether you want to export the native file system or the Episode file system. If you are exporting the native file system, see Exporting the Native File System below. If you are exporting the Episode file system, see Exporting the Episode File System below.

Exporting the Native File System

To export the native file system, perform the following steps.

a. Type 1 and press <Return>.

The dce_config script prompts:

Enter the aggregate name (/export):

Note: The information in parentheses in the previous prompt is not the default value, but only an example of a value to be entered.

b. Type the aggregate name and press <Return>.

You must specify the aggregate name as a mounted file system name, not as a physical device name. For example, to use the device /dev/rz3c, which is mounted as /var, specify /var as the aggregate name.

The dce_config script prompts:

Enter the aggregate ID (1):

c. Type the aggregate ID and press <Return>.

Exporting the Episode File System

To export the Episode File System, perform the following steps:

a. Type 2 and press <Return>.

The dce_config script prompts:

Enter the device name for the aggregate to be exported (i.e. /dev/lvXX):

Note: The information in parentheses in the previous prompt is not the default value, but only an example of a value to be entered.

b. Type the path name of the device on which the selected file system is stored and press <Return>.

The dce_config script prompts:

Enter the LFS fileset name (lfs_set):

c. Type the name of the LFS fileset and press <Return>.

The dce_config script prompts:

Do you want to format partition device_name as an Episode aggregate [n]?.

d. Type y to initialize the device named in a previous prompt as the aggregate to be exported as the Episode aggregate and press <Return>.

The dce_config script displays the following message:

S:****** device_name successfully initialized.

and then the following prompt:

Enter the LFS aggregate name (lfs_aggr):

e. Type a name for the Episode aggregate and press <Return>. The aggregate name must be unique on the machine being configured.

The dce_config script prompts:

Enter the LFS aggregate id (1):

f. Type a number for the aggregate ID and press <Return>. The aggregate ID must be unique on the machine being configured.

After you complete the steps listed in Exporting the Native File System or Exporting the Episode File System, the dce_config displays information about the aggregate and about the servers it is starting:

number of sites: 1
server flags aggr siteAge principal owner
host_name.ch.acme. RW 1 0:00:00 <nil>
FLDB entry created for fileset root.dfs (0,,1) on aggregate 1 of node_name
S:****** Starting dfsbind...
S:****** Starting fxd...
fx: FX server starts listening...

and returns the Additional Server Configuration menu.
