## 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 or zone 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 or zone 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`(1M) command and the `dbmcli` command do not refer to the NIS/NIS+/ldap name services.
