About this task
For example, a DLT drive with the device name
/dev/rmt/3mt may
change to
/dev/rmt/5mt.
Tivoli Storage
Manager SAN Device
Mapping will automatically update device special file names after
the server is restarted if the feature is supported and the device
has been defined to the server. Since the SAN Device Mapping is only
supported by certain operating systems and HBAs, check the
Tivoli Storage
Manager Supported
HBAs for San Device Mapping Technote at
http://www.ibm.com/software/sysmgmt/products/support/IBM_TSM_Supported_Devices_for_AIXHPSUNWIN.html before
reinstalling or upgrading the
Tivoli Storage
Manager device driver.
If the support is not available for your system, the device special
file name will have to be updated manually. Complete the following
steps to manually update device special file names.
- Save the old device name. If the device is configured through
autoconf, the device information has already been saved in the device
information files--mtinfo, lbinfo, and opinfo. If the Tivoli Storage
Manager device driver
is loaded manually through the add_drv command, ensure that
all devices controlled by the Tivoli Storage
Manager device driver
are not being used. Run TSMDLIST in the /opt/tivoli/tsm/devices/bin directory
to collect device information into mtinfo, lbinfo, and opinfo. Rename
the files using the following commands:
- mv /opt/tivoli/tsm/devices/bin/mtinfo /opt/tivoli/tsm/devices/bin/mtinfo.org
- mv /opt/tivoli/tsm/devices/bin/lbinfo /opt/tivoli/tsm/devices/bin/lbinfo.org
- mv /opt/tivoli/tsm/devices/bin/opinfo /opt/tivoli/tsm/devices/bin/opinfo.org
- Once the Tivoli Storage
Manager device
driver has been reinstalled or upgraded, or the device configuration
file has been updated, reconfigure the device through autoconf using
the following command:
/opt/tivoli/tsm/devices/bin/autoconf
- Compare the device names in the old device information files with
those in the new device information files.
If the new device name
in the Special File column is different from the previous name, you
will need to update the device path and provide the new device name
for the DEVICE parameter. The following example shows the device name
for the HP Ultrium 3 drive has been changed from
/dev/rmt/0mt to
/dev/rmt/1mt after
a new device, Sony SDX-550V, was added to the tape configuration file:

- Start the Tivoli Storage
Manager server,
and update the path for the device. If library device names are not
updated, library initialization will fail. Drive will be taken offline
if their device paths are not updated. Use the following commands
to update the paths.
- For a drive:
- UPDate PATH source_name destination_name SRCType=SERVer
DESTType=DRive LIBRary=library_name DEVIce=new_drive_name
- For a library:
- UPDate PATH source_name destination_name SRCType=SERVer
DESTType=LIBRary DEVIce=new_library_name
