Managing NFS and KRPC Kernel Configurations in HP-UX 11i v2 (November 2013)

16
Modifying the value
Certain NFS servers provide 64bit inode numbers for NFS clients. The NFS clients need to be capable
enough to handle 64bit inode numbers. Enable this tunable to support 64bit inode numbers for NFSv3
mounted filesystems.
The support for 64bit inode numbers is applicable to only NFSv3 mounted filesystems. This feature is not
applicable to NFSv2 mounted filesystems, AutoFS, and CacheFS filesystems.
This tunable is not available in the next release of HP-UX. Starting with the HP-UX 11i v3 release, the
support for 64bit inode numbers is enabled by default, and this tunable is not user-configurable.
2.1.18 nfs3_hacc_size
Description
There are two algorithms to search for entries in the access cache: linear and hashed. The default
search algorithm is linear. To use a hashed search, enable the nfs3_new_acache tunable. The speed
of the hashed search is controlled by the number of hash buckets. The nfs3_hacc_size tunable enables
you to specify the number of hash buckets to be used by the NFSv3 access cache.
Tested values
Default: 32
Min: 2
Max: 4000
Restrictions on changing
The nfs3_hacc_size tunable is dynamic. System reboot is not required to activate a change made to
this tunable. Only NFSv3 mount points are affected when you change the value of this tunable.
