Encrypted Volume and File System v2.2 Administrator Guide (777846-001, April 2014)

Restrictions
HP does not support EVFS with Serviceguard in the following configurations:
• EVFS volumes are not supported with Serviceguard multi-node or system multi-node packages.
The only package type supported with EVFS volumes is FAILOVER.
• EVFS is not supported with the Veritas Cluster File System (CFS).
• EVFS is not supported with SG/SGeRAC shared activation.
The following features on ServiceGuard version A.11.19 are not supported by EVFS:
◦ Online package configuration
◦ Partial-startup maintenance mode
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 169).
2. Create new LVM or VxVM volumes for the EVFS volumes. For more detail on this step, see
“Step 2: Creating the HP Serviceguard storage infrastructure” (page 169).
3. Configure EVFS on the configuration node. For more detail on this step, see “Step 3 (EVS
only): Configuring EVS on the configuration node” (page 171). or “Step 3 (EFS only):
Configuring EFS on the configuration node” (page 172)
4. Configure EVFS on the adoptive nodes. For more detail on this step, see “Step 4 (EVS only):
Configuring EVS Volumes on the adoptive nodes” (page 173) or “Step 4 (EFS only): Configuring
EFS volumes on the adoptive nodes” (page 175)
5. Configure Serviceguard to use EVFS. For more detail on this step using modular packages,
see “Step 5: Configuring HP Serviceguard using modular packages” (page 176). For more
detail on this step using legacy packages, see “Step 6: Configuring HP Serviceguard using
legacy packages” (page 180).
Step 1: Installing EVFS
Install EVFS on all Serviceguard nodes that will use EVFS volumes. For more information, see
“Installing EVFS” (page 25).
Step 2: Creating the HP Serviceguard storage infrastructure
Before configuring EVFS, you must create a Serviceguard storage infrastructure for the cluster with
cluster-aware LVM volume groups or VxVM disk groups. This infrastructure must be accessible to
all nodes in the cluster. Select one node to be the configuration node. You will perform most of
