New in This Release The following features were added to Storage Center 7.1. Dell Storage Manager 2016 R2 Dell Storage Manager 2016 R2 or later is required to manage storage systems running Storage Center 7.1. Storage Center 7.1 no longer supports the browser-based GUI known as Storage Center System Manager You must install Dell Storage Manager 2016 R2 or later before updating a storage system to Storage Center 7.1. If you update a storage system to Storage Center 7.
Data Center Bridging (DCB) Support Storage Center 7.1 supports data center bridging (DCB) services. Dell Storage Manager displays DCB information for supported I/O cards, such as switch names and features of the switch port that an iSCSI port is plugged into. Dell Storage Manager also displays information about the Link Layer Discovery Protocol (LLDP), which is used to help support DCB.
NOTE: Live Volume with Auto Failover in Microsoft server environments is supported on SC9000, SC8000, SC7020 and SC4020 storage systems, but it is not supported on SCv2000 series storage systems. Online Import of Volumes from PS Series Storage Arrays An online import creates a destination volume, maps it to the server, then migrates the data to the destination volume. In Storage Center 7.1, performing an online import of volumes from PS Series storage arrays is supported on Red Hat Enterprise Linux 7.
Disk Size Redundancy Level 4.0 TB or larger Dual redundancy is required when adding disks of this size to a new or existing page pool T10-PI Support Storage Center 7.1 adds support for T10 Protection Information (PI) capable drives. T10 Protection Information is an end-to-end data integrity feature that protects against silent data corruption. Volume QoS Profiles Storage Center 7.1 supports Volume QoS Profiles.

Fixed Issues The following sections summarize the issues fixed in Storage Center 7.1. Fixed Issues Related to Data Reduction The following issues are fixed in Storage Center 7.1: Table 3. Fixed Data Reduction Issues in Storage Center 7.1.30 Issue Description SCOS-45843 A large number of events might be generated in the Storage Center system log if a Storage Profile is modified to no longer include the RAID level/tier of the original Storage Profile.
Issue Description SCOS-31054 Enabling Deduplication on a volume that is part of a replication might result in hundreds of Ingestion failure due to SecondaryStorage infrastructure is not ready log messages. SCOS-21275 After updating from Storage Center 7.1.1, a storage system might fail to enable Deduplication on some volumes. Table 6. Fixed Data Reduction Issues in Storage Center 7.1.
Table 10. Fixed Hardware Issues in Storage Center 7.1.20 Issue Description SCOS-41017 An iSCSI I/O card might fail to exit hibernate mode after a reset. SCOS-40447 On SCv2000 series and SC4020 storage systems, the Eth1 IPC path down might go down due to system resource issues. SCOS-40207 On storage systems running Storage Center 7.1.3 or 7.1.4, an iSCSI I/O card might reset because of an IORP timeout that is 10 seconds greater than the IORP requested timeout.
Issue Description SCOS-7943 A controller might reset if the iSCSI initiator logs out from the target, but the initiator fails to terminate the connection. SCOS-6420 An SCv2000 series controller reset might occur due to an incorrect front-end SAS I/O card critical temperature alert. SCOS-6338 Storage Center UPS monitoring does not support newer UPS network cards.
Issue Description SCOS-19269 In a two controller storage system, the active controller might reset during failover after performing a Storage Center update on the peer controller. SCOS-16677 When creating a Live Volume, choosing a destination volume that is mapped to a server might cause the Live Volume to go offline. This might cause other volumes that use Deduplication or Compression on the destination Storage Center to go offline.
Issue Description SCOS-1852 In Storage Center 6.5.10 or later, snapshot messages in system logs might contain an incorrect Position 3072 is past the expected bound error message. SCOS-1546 The Storage Center admin user does not receive an email when a disk folder is close to being full.

Issue Description SCOS-40063 A replacement drive cannot be managed in the same enclosure slot as a failed drive that could not complete the system archiving process. SCOS-2658 A rare timing window in which rebalancing local ports at the same time as volume level operations (view volume creation, mapping/unmapping to a server, etc.) leads to the rebalance not completing.
Issue Description SCOS-26905 A storage system that performs Deduplication might send SupportAssist information to Dell Technical Support that cannot be properly processed. SCOS-26753 A replacement drive might fail to initialize because of depleted Storage Center software resources.
