Planning and Documenting an HA Cluster
Package Configuration Planning
Chapter 4 171
Use VGCHANGE=“vgchange -a y” if you wish to use
non-exclusive activation mode. Single node cluster
configurations must use non-exclusive activation.
CVM_ACTIVATION_CMD
Specifies the command for activation of VERITAS CVM
disk groups.
Use the default CVM_ACTIVATION_CMD=“vxdg -g
\$DiskGroup set activation=exclusivewrite” if
you want disk groups activated in exclusive write
mode.
Use CVM_ACTIVATION_CMD=“vxdg -g \$DiskGroup
set activation=readonly” if you want disk groups
activated in read-only mode.
Use CVM_ACTIVATION_CMD=“vxdg -g \$DiskGroup
set activation=sharedread” if you want disk groups
activated in shared read mode.
Use CVM_ACTIVATION_CMD=“vxdg -g \$DiskGroup
set activation=sharedwrite” if you want disk
groups activated in shared write mode.
NOTE VxVM disk groups do not allow you to select specific
activation commands. The VxVM disk group activation
always uses the same command.
VXVOL
Controls the method of mirror recovery for mirrored
VxVM volumes.
Use the default VXVOL=“vxvol -g \$DiskGroup
startall” if you want the package control script to
wait until recovery has been completed.
Use VXVOL=“vxvol -g \$DiskGroup -o bg
startall” if you want the mirror resynchronization to
occur in parallel with the package startup.
