How can I recall migrated data?
Normally migrated files are automatically recalled from TSM-HSM tape storage when the file is accessed at JUQUEEN (login nodes only), JUDGE (login and compute nodes), JUROPATEST (login nodes only), or JUROPA (GPFS gateway nodes only).
For an explicit recall the native TSM-HSM command dsmrecall is not available. Please use
to start the recall process. These commands will not change any file attribute and the migrated version of the file stays valid.
It is strongly recommended not to use
because this changes the timestamp of the file, so a new backup copy must be created and the file has to be migrated again. These are two additional processes that waste compute ressources if the file is used read only by further processing.
