You can set the minimum redundancy level for a device or an enclosure. The minimum redundancy level is the minimum number of paths that should be active for the device or the enclosure. If the number of paths falls below the minimum redundancy level for the enclosure, a message is sent to the system console and also logged to the Dynamic Multi-Pathing (DMP) log file. Also, notification is sent to vxnotify clients.
The value set for minimum redundancy level is persistent across reboots and product upgrades. If no minimum redundancy level is set, the default value is 0.
You can use the vxdmpadm setattr command to set the minimum redundancy level.
To specify the minimum number of active paths
# vxdmpadm setattr enclosure|arrayname|arraytype component-name redundancy=value
where value is the number of active paths.
For example, to set the minimum redundancy level for the enclosure HDS9500-ALUA0:
# vxdmpadm setattr enclosure HDS9500-ALUA0 redundancy=2
