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 GPFS product information.

Running HSM on GPFS file systems that use Active File Management file sets is explained in Guidance for integrating IBM Spectrum Scale AFM with IBM Spectrum Protect .

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.

Supported Clients

This option is valid for backup-archive clients that run on AIX® and Linux systems.

Options File

Place this option in the dsm.sys file before any server stanzas.

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.
