Veritas Storage Foundation 5.1 SP1 Cluster File System Installation Guide (5900-1510, April 2011)

below describes how to verify that the vxiod daemons are running, and how to
start them if necessary.
To verify that vxiod daemons are running, enter the following command:
# vxiod
The vxiod daemon is a kernel thread and is not visible using the ps command.
If, for example, 16 vxiod daemons are running, the following message displays:
16 volume I/O daemons running
where 16 is the number of vxiod daemons currently running. If no vxiod daemons
are currently running, start some by entering this command:
# vxiod set no_of_daemons
where the number of daemons ranges from 1 to16. Syamntec recommends that
at least one vxiod daemon should be run for each CPU in the system.
For more information, see the vxiod(1M) manual page.
Enabling optional cluster support in VxVM
This release includes an optional cluster feature that enables VxVM to be used in
a cluster environment. The cluster functionality in VxVM allows multiple hosts
to simultaneously access and manage a set of disks under VxVM control. A cluster
is a set of hosts sharing a set of disks; each host is referred to as a node in the
cluster.
The VxVM cluster feature requires a license, which can be obtained from your
Customer Support channel.
To enable the cluster functionality in VxVM
1
Obtain a license for the VxVM cluster feature.
2
Install the software packages onto each system (node) to be included in the
cluster.
3
Create the configuration files required to form a cluster.
