redundant power supply fails.
SCOS-43176 On SCv3000 series, SC5020, and SC7020 storage systems, the PCIe Link Reset command might fail
for 10 GbE iSCSI host bus adapters, which causes the HBA to go down.
SCOS-42250 When an initiator performs an iSCSI login to a 10 GbE iSCSI host bus adapter, the HBA might reset
