Verifying the VxFS cache area and monitoring the caching

After the SmartIO feature is configured, you can verify that the cache area is present and that caching is occurring.

To verify and monitor the cache area

  1. Use the following command to display information about the cache areas on the system.
    SmartIO> cache list
    NAME          TYPE SIZE  ASSOC-TYPE  STATE   DEVICE 
sfcachearea_1 VxFS 7.97g AUTO        ONLINE  sdb
  2. To display information about a specific file: 
    SmartIO> file list target1
    /vx/target1:
READ CACHE    WRITEBACK    MODE    PINNED  NAME
   39.0 MB         0 KB    read    yes     /vx/target1
  3. To see statistics on the cache usage, use the following command: 
    SmartIO> fs stat target1
    Cache Size:    7.97 GB
Cache Utilization:    1 GB ( 12.56 %)

Read Cache
Hit Ratio    Data Read    Data Written

/vx/target1:
   0.00 %         0 KB         0 KB

    The output displays statistics for the cached data.

    See Viewing the caching statistics for a cache area .
