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.
Options File
