Preparing the Nodes and Disks

This section contains the procedures you need to prepare the nodes and disks.

How to Prepare the Nodes

Use this procedure to prepare for the installation and configuration of liveCache.

1. Assume a root role on all of the nodes.
2. Configure the svc:/system/name-service/switch:default SMF service.
   1. On each node that can master the liveCache resource, include one of the following entries for group, project, an passwd database entries in the svc:/system/name-service/switch:default SMF service.

      config/database:
      config/database: files 
      config/database: files [NOTFOUND=return] nis
      config/database: files [NOTFOUND=return] nisplus
      config/database: files [NOTFOUND=return] ldap

      Example:

      # svccfg -s name-service/switch 
      svc:/system/name-service/switch> \
      setprop config/passwd = astring: "files [NOTFOUND=return] nis" 
      svc:/system/name-service/switch> exit
      
      # svcadm refresh name-service/switch 
      # svcadm restart name-service/switch

   2. On each node that can master the liveCache resource, ensure that files appears first for the protocols database entry in the svc:/system/name-service/switch:default SMF service.

      Example:

      protocols: files nis

   HA for SAP liveCache uses the su - user command and the dbmcli command to start and stop liveCache.

   The network information name service might become unavailable when a cluster node's public network fails. Implementing the preceding changes to the svc:/system/name-service/switch:default SMF service file ensures that the su command and the dbmcli command do not refer to the NIS/NIS+/LDAP name services.
