hsmoptimizedrecallonly

The hsmoptimizedrecallonly option specifies whether the space management client blocks all non-optimized recall processes.

By default, with hsmoptimizedrecallonly set to No, all recalls are allowed and users and applications can access all migrated files. If hsmoptimizedrecallonly is set to YES, access to migrated files, which require recalling data from the IBM Spectrum Protect server, are blocked and the application receives no access and the error code EACCES. No access includes reading the content of migrated files, and changing the content to migrated files. Reading of premigrated files is not blocked as the data is located in the local file system. If a recall is blocked, the dsmrecalld command writes the message ANS2735W to the error log file every 24 hours. If the recall is triggered by the dsmrecall command or the dsmc command, the message ANS4007E is also logged to the error log file.

To recall the content of migrated files with hsmoptimizedrecallonly set to YES, compile a list of files, and follow the instructions for Recalling files with optimization.

Supported Clients

The option is available only for IBM Spectrum Scale AIX® clients and IBM Spectrum Scale Linux® clients.
