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

new_package
Specifies the name for the new package control script file, such as
/etc/cmcluster/my_pkg/my_pkg_evfs.sh.
Modifying the Package Configuration File
You must modify the RUN_SCRIPT and HALT_SCRIPT variables in the package configuration
file to use the converted package control script. For example:
RUN_SCRIPT /etc/cmcluster/my_pkg/my_pkg_evfs.sh
:
:
HALT_SCRIPT /etc/cmcluster/my_pkg/my_pkg_evfs.sh
Step 6e: Adding the EVFS Volumes to the Package Control Script
Edit the package control script to configure the EVFS volumes that you want Serviceguard to
enable when the package starts, and the file systems to be mounted on the EVFS volumes.
• If the EVFS volumes are created on VxVM volumes, specify the VxVM disk groups in the
VXVM_DG[] parameters in the package control script.
• Specify the EVFS volumes that you want Serviceguard to enable in the LV[] parameters
• Specify the file systems you want Serviceguard to mount on the EVFS volumes in the FS[]
parameters
• Specify the appropriate file system type in the FS_TYPE[] parameters
If you started with an existing package control script, remove the appropriate LVM or VxVM
volumes from the LV[] and FS[] entries and replace them with EVFS volumes.
Serviceguard will enable the EVFS volumes when the package starts and disable the EVFS
volumes when the package fails over.
LVM and VxVM Legacy package example
LVM Example
LV[0]="/dev/evfs/vg02/lvol5"; FS[0]="/opt/crypto"; FS_MOUNT_OPT[0]=
"-o rw"
#FS_TYPE[0]="vxfs"
VxVM Example
VXVM_DG[0]="evfsdg"
:
:
LV[0]="/dev/evfs/vx/dsk/evfsdg/vol5"; FS[0]="/opt/crypto"; FS_MOUNT_OPT[0]=
"-o rw"
#FS_TYPE[0]="vxfs"
Step 6f: Installing the EVFS Control Script
Create a copy of the EVFS control script /etc/evfs/opt/cmcluster/evfs_sg.sh, and place
the copy into the package sub-directory.
For example:
# cp /etc/evfs/opt/cmcluster/evfs_sg.sh /etc/cmcluster/my_pkg/evfs_sg.sh
Step 6g: Verifying the Script
Verify the package configuration using the cmcheckconf command. Build and distribute the
cluster configuration as described in the Serviceguard product documentation.
