Configure VSM Archive Devices
Configure HSM HSM VMS archive devices.
Configure the persistent archive devices in the MCF (/etc/opt/vsm/mcf). The supported devices are listed in the /etc/opt/vsm/inquiry.conf file.
Network attached robots are not supported. Use the ACSLS SCSI Media Changer for the SL8500 robot. ACSLS 8.2 or 8.3 is required for the SCSI Media Changer option.
- Use the command lsscsi -g to list the SCSI devices.
- Use the mtx command to access the robot.
- Use the mt command to access the tape drives.

If necessary, rebuild the symlinks if they are missing, reboot, and verify that they exist. Use the following command to rebuild the symlinks:
tas-mdc1# /sbin/udevadm trigger
Device mapper (DM) multipath is the standard configuration for all nodes. Configure DM multipath if there are multiple paths to devices from service nodes. All nodes configured for DM multipath have a connection to each storage array controller. Specific WWID values must be added to the
multipaths {} section of the /etc/multipath.conf file so that devices have persistent names each time the node boots.## Example of alias entries
