To add all the tape drives connected to the ACSLS server to the MMS configuration with the default attributes:

mmsadm create -t drive -o connection=acsls_server

Example:Creating All Drives on AcslsHost

mmsadm create -t drive -o connection=AcslsHost

To add one drive to the MMS configuration with the default attributes:

mmsadm create -t drive drive_name

Example:Creating MyDrive

mmsadm create -t drive MyDrive

To add one drive to the MMS configuration with a specific attribute:

mmsadm create -t drive -o options=x drive_name

Example:Creating MyDrive with a 15 megabyte trace file

mmsadm create -t drive -o trace-file-size=15M MyDrive

To modify the attributes of a drive:

mmsadm set -t drive -o options=x drive_name

Example:Changing MyDrive to use a 5 megabyte trace file

mmsadm set -t drive -o trace-file-size=5M MyDrive

To verify a new or changed drive:

mmsadm list -t drive _drive_name_
