Using vxtunefs to obtain tuning information
Check the setting of the qio_cache_enable flag for each file system using the vxtunefs command.
To obtain information on only the qio_cache_enable flag setting
- Use the grep command with vxtunefs:
For AIX and Solaris:
# /opt/VRTS/bin/vxtunefs /mount_point | grep qio_cache_enable
For example:
For AIX and Solaris:
# /opt/VRTS/bin/vxtunefs /db01 | grep qio_cache_enable
where /db01 is the name of the file system. This command displays only the qio_cache_enable setting as follows:
qio_cache_enable = 0
You can also use the vxtunefs command to obtain a more complete list of I/O characteristics and tuning statistics.
See the vxtunefs (1) manual page.
To obtain information on all vxtunefs system parameters
- Use the vxtunefs command without grep:
# /opt/VRTS/bin/vxtunefs /mount_point
For example:
# /opt/VRTS/bin/vxtunefs /db01
The vxtunefs command displays output similar to the following:
Filesystem i/o parameters for /db01 read_pref_io = 65536 read_nstream = 1 read_unit_io = 65536 write_pref_io = 65536 write_nstream = 1 write_unit_io = 65536 pref_strength = 10 buf_breakup_size = 131072 discovered_direct_iosz = 262144 max_direct_iosz = 1048576 default_indir_size = 8192 qio_cache_enable = 0 odm_cache_enable = 0 write_throttle = 0 max_diskq = 1048576 initial_extent_size = 1 max_seqio_extent_size = 2048 max_buf_data_size = 8192 hsm_write_prealloc = 0 read_ahead = 1 inode_aging_size = 0 inode_aging_count = 0 fcl_maxalloc = 887660544 fcl_keeptime = 0 fcl_winterval = 3600 fcl_ointerval = 600 oltp_load = 0 delicache_enable = 1 thin_friendly_alloc = 0 dalloc_enable = 1 dalloc_limit = 90
The vxtunefs(1) manual pages contain a complete description of vxtunefs parameters and the tuning instructions.
