vxdctl Utility

When the vxdctl utility is executed as “vxdctlenable”, if DMP

identiﬁes a DISABLED primary path of a shared disk in an

active/passive type disk array as physically accessible, this path is

marked as ENABLED. However, I/Os continue to use the current path

and are not routed through the path that has been marked ENABLED.

This is a deviation from single host behavior of this command where I/Os

automatically failback to the primary path.

The vxdctl utility manages some aspects of the vxconfigd volume

conﬁguration daemon.The -c option can be used to request cluster

information. To use the vxdctl utility to determine whether the

vxconfigd daemon is enabled and/or running, use the following

command:

# vxdctl -c mode

Depending on the circumstances, this produces output similar to the

following:

mode: enabled: cluster active - MASTER

mode: enabled: cluster active - SLAVE

mode: enabled: cluster inactive

mode: enabled: cluster active - role not set

NOTE If the vxconfigd daemon is disabled, no cluster information is displayed.

The vxdctl utility lists the cluster protocol version and cluster protocol

range. After all the nodes in the cluster are updated with the new cluster

protocol, update the entire cluster using the following command:

# vxdctl upgrade

Check the existing cluster protocol version using the following command:

# vxdctl protocolversion
