—Use the storage management software to collect and save a support bundle of your storage array. From the
Array Management Window, select Monitor >> Health >> Collect Support Data. Then name and specify a
location on your system where you want to store the support bundle.
—Use the command line interface (CLI) to run the save storageArray supportData command to
