Defines a path as being the primary path for a JBOD disk array.
The following example specifies a primary path for a JBOD disk
array:
# vxdmpadm setattr path c3t10d0 \
pathtype=primary
primary
Defines a path as being the secondary path for a JBOD disk array.
The following example specifies a secondary path for a JBOD disk
array:
# vxdmpadm setattr path c4t10d0 \
pathtype=secondary
secondary
Marks a standby (failover) path that it is not used for normal I/O
scheduling. This path is used if there are no active paths available
for I/O. The next example specifies a standby path for an A/P-C
disk array:
# vxdmpadm setattr path c2t10d0 \
pathtype=standby
standby
Displaying the redundancy level of a device or enclosure
Use the vxdmpadm getdmpnode command to list the devices with less than the
required redundancy level.
To list the devices on a specified enclosure with fewer than a given number of
enabled paths, use the following command:
# vxdmpadm getdmpnode enclosure=encl_name redundancy=value
For example, to list the devices with fewer than 3 enabled paths, use the following
command:
# vxdmpadm getdmpnode enclosure=EMC_CLARiiON0 redundancy=3
