Setting up the cache cluster

This topic lists the steps to set up the cache cluster.

1. To determine the nodes of the GPFS cluster that functions as application nodes and the nodes that function as the gateway nodes, run the mmchnode --gateway -N Node1,Node2,... command.
2. To start GPFS, run the mmstartup -a command.
3. To mount the file system, run the mmmount Device -a command.
4. Mount the home filesystem on the cache cluster remotely.
5. To create an AFM fileset and link it, run the following command:

   mmcrfileset Device Fileset -p afmTarget=Home-Path --inode-space=new
   -p afmMode=single-writer | read-only | local-updates | independent-writer
   
   mmlinkfileset device fileset -J /fsmount-path/fileset

6. Access the AFM fileset.

   mmafmctl Device getstate run on the cache cluster displays the fileset state and other details.
