Issue Description
SCOS-45629 If unsupported drives were added to a storage system by technical support using CLI commands, the
drives might go offline when the Storage Center software is updated on the storage system.
SCOS-45475 A controller might reset because of multiple FCoE RISC PAUSE hangs.
SCOS-45155 While attempting to gather enclosure logs from an SC400 and SC420 expansion enclosure, the
expansion enclosure might unexpectedly reset.
SCOS-43877 On an SC4020 storage system, a storage controller might incorrectly report “Cache board battery
charge is low”.
SCOS-43848 On SCv2000 series, SCv3000 series, SC4020, SC5020, and SC7020 storage systems that are
destinations for replications using the embedded iSCSI ports, if the source system uses 10 GbE iSCSI
host bus adapters, replication performance may significantly drop until the source system 10 GbE
iSCSI HBAs are restarted.
SCOS-43703 On SCv2000 series and SC4020 storage systems, the write cache might to go down if one of the
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
and fail to exit the hibernate mode.
SCOS-39114 A single SSD failure might cause high latency on a storage system.
SCOS-22260 iSCSI I/O cards fail to honor an MTU value change made on a router.
SCOS-22152 A drive might become stuck performing a survey if the drive goes down and the drive does not
receive writes after becoming unhealthy.
