Starting the volume I/O daemon

The volume I/O daemon (vxiod) provides extended I/O operations without blocking calling processes. Several vxiod daemons are usually started at system boot time after initial installation, and they should be running at all times. The procedure 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


  Note   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 16

where 16 is the desired number of vxiod daemons. It is recommended that at least one vxiod daemon should be run for each CPU in the system.

For more information, see the vxiod(1M) manual page.
