Enabling HCC on Direct NFS Client

Perform these steps to enable Hybrid Columnar Compression (HCC) on Direct NFS Client:

1. Ensure that SNMP is enabled on the ZFS storage server. For example:

   # snmpinfo -m get -c public -v -h server_name 1.3.6.1.4.1.42.2.225.1.4.2.0
   enterprises.42.2.225.1.4.2.0 = 53:75:6e:20:53:74:6f:72:61:67:65:20:37:34:31:30
   

   The above sequence of bytes 53:75:6e:....:31:30 is an ascii character representation for Sun Storage 7410.
2. If SNMP is enabled on an interface other than the NFS server, then configure oranfstab using the management parameter.
3. If SNMP is configured using a community string other than public, then configure oranfstab file using the community parameter.
4. Ensure that libnetsnmp.so is installed. If libnetsnmp.so is not installed, download and install it from the following URL:
