Running a CMC LM

This section contains steps you can follow to get the CMC (Connected Media Changer) LM for your shuttle complex running. When shuttle connections exist between libraries that are defined in TSLM, you must have the CMC LM for your shuttle complex running before TSLM applications can mount tape cartridges to drives in remote libraries.

Get the CMC LM for your shuttle complex running by completing the following sequence of tasks to configure, start, and initialize the CMC LM:

Configure the CMC LM:
- Prepare the configuration files for the CMC LM for your shuttle complex (see Preparing a CMC LM configuration file
Start the CMC LM:
- Start the process for the CMC LM for LTO tape libraries or 3592 tape libraries by issuing the following command as user ermm: $ ermmLmStart

Preparing a CMC LM configuration file

These CMC LM sample configuration files are under the /opt/IBM/ermm/conf directory:

lm-CMCLTOLM.xml.smp: This is a sample configuration file of CMC LM for LTO tape libraries
lm-CMC3592LM.xml.smp: This is a sample configuration file of CMC LM for 3592 tape libraries.

You must create an .xml configuration file for use by the CMC LM for your library. Create .xml configuration files from the .smp files by using either of the following methods:

Copy method: Copy lm-CMCLTOLM.xml.smp to lm-CMCLTOLM.xml, and copy lm-CMC3592LM.xml.smp to lm-CMC3592LM.xml.
ermmLmConfig method: Run the following ermmLmConfig commands under the /opt/IBM/ermm/bin directory:
- Use the following command to create lm-CMCLTOLM.xml:
```
# /opt/IBM/ermm/bin/ermmLmConfig -library <any string> -lm <any string>
-type cmc -cmctype LTO
```
- Use the following command to create lm-CMC3592LM.xml:
```
# /opt/IBM/ermm/bin/ermmLmConfig -library <any string> -lm <any string>
-type cmc -cmctype 3592
```
