Updating idle time before worker nodes are removed

Complete the following steps to adjust the idle time for dynamic hosts that are returning to IBM Cloud®. By default the value is set to 10 minutes.

Find the lsf.conf file on your management host. Typically, the file is located in the folder $LSF_ENVDIR environment variable. In a typical installation, it would be in the /opt/ibm/lsf/conf/lsf.conf folder.
Update the LSB_RC_EXTERNAL_HOST_IDLE_TIME property. See the following sample content for an example:
```
#enable IDLE time to return the VMs

LSB_RC_EXTERNAL_HOST_IDLE_TIME=10
```
Run the following commands to make the changes:
```
lsadmin reconfig
```
```
badmin mbdrestart
```
