multipathing configuration data, you need to collect configuration information for the
host and DS8000 HBAs that includes the bandwidth of each adapter.
Table 7-13 Path configuration data
c. Format the data and correlate the host LUNs with their associated DS8000 resources.
Formatting the data is not required for analysis, but it is easier to analyze formatted
data in a spreadsheet.
The following steps represent the logical steps that are required ...
