Understanding LUN and path instance numbering
When Secure Path for Active-Passive is installed or when an array is added to a configuration, Secure
Path for Active-Passive numbers LUNs sequentially starting with target 0 LUN 0. This sequential
numbering may not match the numbering of units on the array. For example, unit D12 on an HSG80
may have a device instance number of c12t0d6 as seen in the spmgr display output. The c12
is the next available instance number when the array was added and the t0d6 is simply the next
LUN added following c12t0d5.
