List Controllers

The vxdmpadm listctlr command lists speciﬁed disk controllers

connected to the host. This command also lists the controllers on a

speciﬁed enclosure or a particular type of enclosure, as follows:

# vxdmpadm listctlr all

# vxdmpadm listctlr enclosure=nikee0 type=NIKE

List Enclosure

The list enclosure command displays all attributes of the enclosure(s)

listed on the command line, as follows:

# vxdmpadm listenclosure nike0 fc1010d0

DMP Restore Daemon

The DMP restore daemon periodically analyzes the health of the paths.

The restore daemon is started at the system startup time with default

attributes. The interval of polling can be set by using the following

command:

# vxdmpadm start restore interval=400

Depending on the policy speciﬁed restore checks the health of paths that

were previously disabled or checks all paths. The paths that are back

online are revived and the inaccessible paths are disabled. Set the policy

using the following command:

# vxdmpadm start restore policy=check_all

To stop the restore daemon enter the command:

# vxdmpadm stop restore

The intervals of restore daemons running and the numbers of error

daemons are obtained using the following commands:

# vxdmpadm stat restored

# vxdmpadm stat errord
