If you suspect a hardware issue with either the Dell MD3860 or the NetApp storage, a troubleshooting support bundle will be required if opening a case with Broadcom support.
There is one way to generate a support bundle on the Dell MD3860s and two ways for the NetApp storage.
Dell (using MDSM)
NetApp (using SANtricity)
NetApp (using SMcli)
SMcli -n array_name -c 'save storageArray supportData file="/home/supportbundle";'
