Encrypted Volume and File System v1.1 Administrator's Guide

Configuration Overview
EVFS includes the following files for operation with Serviceguard:
• /etc/evfs/opt/cmcluster/evfs_sg.sh
EVFS control script
The following script is required for legacy packages only:
• /etc/evfs/opt/cmcluster/evfssgconv
Utility for converting existing package control scripts to make them execute the EVFS control
script
The following two scripts are required for modular packages only:
• /etc/evfs/opt/cmcluster/evfs.1
EVFS Attribute Definition File (ADF)
• /etc/evfs/opt/cmcluster/evfs.sh
EVFS module script
Use the following procedure to configure EVFS volumes in a Serviceguard failover package:
1. Install EVFS on all nodes in the cluster that will use the EVFS volumes. For more detail on
this step, see “Step 1: Installing EVFS” (page 156).
2. Create new LVM or VxVM volumes for the EVFS volumes. For more detail on this step, see
“Step 2: Creating the Serviceguard Storage Infrastructure” (page 157).
3. Configure EVFS on the configuration node. For more detail on this step, see “Step 3:
Configuring EVFS on the Configuration Node” (page 159).
4. Configure EVFS on the adoptive nodes. For more detail on this step, see “Step 4: Configuring
EVFS Volumes on the Adoptive Nodes” (page 161).
5. Configure Serviceguard to use EVFS. For more detail on this step using modular packages,
see “Step 5: Configuring Serviceguard using Modular packages” (page 164). For more detail
on this step using legacy packages, see “Step 6: Configuring Serviceguard using Legacy
packages” (page 167).
