Using the TMS tag information

When FATMEN is installed with the TMS option, access to the TMS tag information is possible. The TMS keeps two tags for each volume. As FATMEN already contains a fair amount of user information in the catalogue, it is not recommended that these tags be used to store further such information. Firstly, the TMS tags are only available for data on tape and secondly, access to the TMS tags is slower and less efficient than to information in the FATMEN catalogue. It can be useful to set the text tag to the generic name. If, for example, the generic name

//cern/l3/prod/data/sdsutt/cc00ftgu

points to the volume XP3088 one could set the text tag on this volume to be

//cern/l3/prod/data/sdsutt/cc00ftgu

This means that if we find the tape XP3088 somewhere and want to know what is on it, we can query the TMS and have a pointer to the entry in the FATMEN catalogue. Alternatively, one could use the command

SEARCH */* VID=XP3088

The TMS text tag can be set to the generic name with the shell command

tag //cern/l3/prod/data/sdsutt/cc00ftgu -s
