Maintaining Your System Files

Periodically, you may need to perform the following tasks to maintain your file system:

Note: This file format is used for TUXCONFIG, TLOG, and /Q.

How to Print the Universal Device List (UDL)

To print a UDL, complete the following procedure:

Run tmadmin -c.
Enter the following command:
```
lidl
```
To specify the device from which you want to obtain the UDL, you have a choice of two methods:
- Specify the device on the lidl command line:
```
-z device_name [devindx]
```
- Set the environment variable FSCONFIG to the name of the desired device.

How to Print VTOC Information

To print VTOC information, complete the following procedure.

Run tmadmin -c.
To get information about all VTOC table entries, enter the following command:
```
livtoc
```
To specify the device from which you want to obtain the VTOC, you have a choice of two methods:
- Specify the following on the lidl command line:
```
-z device name [devindx]
```
- Set the environment variable FSCONFIG to the name of the desired device.

How to Reinitialize a Device

To reinitialize a device that is included on a device list, complete the following procedure.

Run tmadmin -c.
Enter the following command:
```
initdl [-z devicename] [-yes] devindx
```
Note: The value of devindx is the index to the file to be destroyed.
You can specify the device by:
- Entering its name after the -z option (as shown here), or
- Setting the environment variable FSCONFIG to the device name
If you include the -yes option on the command line, you are not prompted to confirm your intention to destroy the file before the file is actually destroyed.

How to Create a Device List

To create a device list, complete the following procedure.

Run tmadmin -c.
Enter the following command:
```
crdl [-z devicename] [-b blocks]
```
- The value of devicename [devindx] is the desired device name. (Another way to assign a name to a new device is by setting the FSCONFIG environment variable to the desired device name.)
- The value of blocks is the number of blocks needed. The default is 1000 blocks.
  Note: Because 35 blocks are needed for the administrative overhead associated with a TLOG, be sure to assign a value higher than 35 when you create a TLOG.

How to Destroy a Device List

To destroy a device list with index devindx, complete the following procedure.

Run tmadmin -c.
Enter the following command:
```
dsdl [-z devicename] [yes] [devindx]
```
Note: The value of devindx is the index to the file to be destroyed.
You can specify the device by:
- Entering its name after the -z option (as shown here), or
- Setting the environment variable FSCONFIG to the device name
If you include the yes option on the command line, you are not prompted to confirm your intention to destroy the file before the file is actually destroyed.
