Afmskipuncachedfiles
The afmskipuncachedfiles option specifies whether uncached and dirty files in General Parallel File System (GPFS) Active File Management file sets are processed for backup, archive, and migration operations.
GPFS Active File Management and uncached and dirty file states are explained in IBM Storage Scale product information.
Running HSM on GPFS file systems that use Active File Management file sets is explained in Configuring IBM Storage Protect for IBM Storage Scale Active File Management.
If you back up, archive, or migrate files from a file system that contains Active File Management
file sets, set afmskipuncachedfiles=yes.
Restriction: If Active File Management is running in Local Update (LU) mode, the
afmskipuncachedfiles option in the cache file set must be set to
No.

Parameters
- NO
- The Active File Management file state is ignored during backup, archive, and migration operations. Migration operations on uncached or dirty files fail and yield error message ANS9525E. Backup and archive operations on uncached files require Active File Management fetch operations. The fetch operations can cause significant network traffic between the Active File Management home and cache. This parameter is the default.
- YES
- Uncached or dirty files in Active File Management file sets are skipped during backup, archive, and migration processing.
