• • • • SC5020 SC4020 SCv3000 Series SCv2000 Series NOTE: Storage Center 7.3 supports cabling mixed-speed expansion enclosures. SC400, SC420, and SC420F expansion enclosures can be cabled with SC200 and SC220 expansion enclosures. New in This Release The following features were added to Storage Center 7.3: Advanced Restripe Several enhancements have been made to the RAID restripe process to integrate and remove disks from a storage system.
Data-in-Place Migration Data-in-Place Migration is a new licensed feature in Storage Center 7.3.2 that can be used to upgrade an SC4020 storage system to an SC5020 or SC7020 storage system. Distributed Sparing Distributed sparing allocates spare disk space across all drives rather than reserving an entire drive as a spare. Distributed sparing enables the storage system to use all disks in a balanced and optimized manner, which ensures the fastest recovery time following a drive failure.

Fixed Issues Related to Alerts and Reporting The following issues are fixed in Storage Center 7.3: Table 5.
Issue Description SCOS-18986 The Secure Console connection alert might fail to clear after Secure Console is disabled. Fixed Issues Related to Data Reduction The following issues are fixed in Storage Center 7.3: Table 8. Fixed Data Reduction Issues in Storage Center 7.3.20 Issue Description SCOS-54104 Deduplication might fail to occur on a storage system because the Data Optimazation Dedup Capable attributes are set to false after a storage system is updated to Storage Center 7.3.4 or later.
Issue Description SCOS-48621 In rare instances, deduplication and compression might erroneously return pagepool pages with incorrect tags, which cause payload error counts to be incremented on the pagepool freelist. SCOS-47507 Slow deduplication ingest rates might occur when multiple Storage Center processes are working on the same volume simultaneously. SCOS-46684 A controller might reset because of multiple small memory allocation requests.
Issue Description EH-1347 Storage Center might fail to recognize 10GBASE-T mezzanine cards if they are installed in SCv3000 series or SC5020 storage systems that were deployed without mezzanine cards. Table 17. Fixed Hardware Issues in Storage Center 7.3.2 Issue Description SCOS-51118 An SC9000 controller might reset because of alignment changes to the virtual address space.
Fixed Issues Related to Licensing, SupportAssist, and Updating The following issues are fixed in Storage Center 7.3: Table 19. Fixed Licensing, SupportAssist, and Updating Issues in Storage Center 7.3.11 Issue Description SCOS-54886 Storage Center might stop sending SupportAssist diagnostic data to CloudIQ if the Phone Home Daemon enters a recursive loop.
Issue Description the active storage controller. As a result, the storage controllers in the storage system might end up with different versions of the low-level firmware. SCOS-32283 On SCv2000 series and SC4020 storage systems, the Storage Center software might indicate that a prior version of software is available to install after performing a Storage Center ISO update.
Fixed Issues Related to Security The following issues are fixed in Storage Center 7.3: Table 29. Fixed Security Issues in Storage Center 7.3.20 Issue Description SCOS-48576 A security scan showed a possible vulnerability in the Apache software in the Storage Center management interface. Table 30. Fixed Security Issues in Storage Center 7.3.11 Issue Description SCOS-55131 Self-signed SSL certificates that the Storage Center generates have been identified as security vulnerabilities.
Issue Description SCOS-55713 View volumes cannot be created on a Storage Center if a user creates a traffic profile of the type Group with a name that starts with text 'Default'. SCOS-55306 Data progression might become suspended and fail to resume if DPM defrag and data progression are running simultaneously. SCOS-55267 SNMP is unable to retrieve information about the power supply and cooling fan modules on SC7020, SC5020, and SCv3000 series storage systems.
Table 34. Fixed Storage Management Issues in Storage Center 7.3.6 Issue Description SCOS-53212 A storage system using RAID rebalance might create a RAID device with an unexpectedly large stripe size. Table 35. Fixed Storage Management Issues in Storage Center 7.3.5 Issue Description SCOS-52932 A controller might reset if volumes with RAID copies are deleted during a RAID rebuild.
Issue Description SCOS-45755 The volume space consumption limit cannot be set above 2 TB using Storage Manager. SCOS-45304 Storage Center is unable to create a mapping profile for a volume that is mapped to a Linux server without an HBA. SCOS-45181 On SCv2000 series, SCv3000 series, SC4020, SC5020, and SC7020 storage systems, a controller might reset if a boot personality is detached and then the IPv6 address is removed from the embedded iSCSI ports.
Table 42. User Interface Issues Fixed in Storage Center 7.3.1 Issue Description SCOS-41051 When the Storage Manager Client is connected to a Storage Center through a Data Collector, the Storage Manager Client does not allow you to change the name of an enclosure and asset tag. SCOS-25031 After a controller failover, the peer controller might be reported as down by both SNMP and a Storage Manager Client that is directly connected to the peer controller.
Open Issues The following sections summarize the open issues in Storage Center 7.3. Open Issues Related to Alerts and Reporting The following open issues are related to alerts and reporting: Table 47. Open Alerts and Reporting Issues Issue Description SCOS-38226 In rare instances, a Sync LiveVolume Auto Failover alert is not cleared when the condition is corrected. Workaround: Use Storage Manager to manually acknowledge and clear the alert.
Issue Description Workaround: Remove the server from the cluster through the OS first. After the server is rebooted, remove the server object using Storage Manager. When a server is removed from one Storage Center only, or a volume is un-mapped on one Storage Center only, the persistent reservations might not stay consistent between primary volume and secondary volume. Workaround: When removing a server from a cluster or simply un-mapping a volume, follow the below order 1.
Open Issues Related to Vendors The following open issues are related to vendors: Table 53. Open Vendor Issues Issue Description SQAI-9 An ESXi 5.5 (Update 3b) host using FCoE and QLogic 8262 converged network adapters (CNAs) might cause the host to fail during controller failovers. Workaround: Update the QLogic firmware on the adapter. The QLogic firmware is available at https://www.dell.com/support/home/us/en/19/Drivers/DriversDetails?driverId=6RGDW.
