Enabling Cached ODM for file systems
Cached ODM is initially disabled on a file system. You enable Cached ODM for a file system by setting the odm_cache_enable option of the vxtunefs command after the file system is mounted.
See the vxtunefs
(1M) manual page.
Note: |
The vxtunefs command enables conditional caching for all of the ODM files on the file system. |
To enable Cached ODM for a file system
-
Enable Cached ODM on the VxFS file system /database01
:
# vxtunefs -s -o odm_cache_enable=1 /database01
-
Optionally, you can make this setting persistent across mounts by adding a file system entry in the file /etc/vx/tunefstab
:
/dev/vx/dsk/datadg/database01 odm_cache_enable=1
See the tunefstab
(4) manual page.
