Unmap support requires the use of the command line utility esxcli in order to perform unmap operations on VMFS Datastores. This includes ESXi v6.5 Datastores. ESXi does not support unmap with PS series arrays in the following three cases: • The EQL volume is replicated. (SYNC or ASYNC). This restriction is true for all operating systems supporting unmap. • The VMFS Datastore was updated from VMFS v3.x to VMFS v5.0. It must be formatted at VMFS v5+ in order to support unmap • ESXi v6.5 offers VMFS automatic unmap on VMFS v6.x Datastores. However, VMware requires that the unmap granularity be 1MB or less. PS Series arrays use an unmap granularity of 15 MB. • ESXi v6.7 update 2 adds support for VMFS6 automatic unmap processing on storage arrays and devices that report to ESXi hosts an unmap granularity value greater than 1 MB. On arrays that report granularity of 1 MB and less, the unmap operation is supported if the granularity is a factor of 1 MB. Volumes Error When Deleting Volume With Multiple Snapshots Online If you attempt to delete a volume with multiple snapshots online, the following (incorrect) error is generated: No Snapshot exists for volume_name. Issues Corrected in Version 10.0.3 This version of PS Series firmware includes all fixed issues that were incorporated into earlier releases. Replication • Cross-platform replications from a Storage Center system with Chelsio T3 iSCSI HBAs to a PS Series array stop approximately every six to eight weeks. • Issues with Cluster Interprocess Communication (CIPC) might prevent the replication of a volume from a Storage Center system to a PS Series array. User Interface • If the Secure Communication option is enabled, users are unable to establish a connection to the Group Manager GUI after updating to Java 8 build 201. Other • The ocps daemon running on PS Series arrays only supported the anonymous Diffie-Hellman key exchange protocol. • Updated the time zone data with the latest information from the IANA Time Zone Database. Issues Corrected in Version 10.0.2 This version of PS Series firmware includes all bug fixes that were incorporated into earlier releases. Replication • User could not replicate a volume from a PS Series storage array to a Storage Center using cross-platform replication. After a controller failover, the replication completed successfully. • During a cross-platform replication from PS to SC, if one of the controllers on the SC side rebooted, and a rebalance of ports was performed after the controller came back up, a stale session entry remained on the PS side. SAN Headquarters (SAN HQ) • While running SAN HQ on a PS6210 array, user reported a large number of the following event: fsmRequest.cc:245:DIAG::7.6.5:context missing in read callback. User Interface • User could not open Group Manager nor use Dell Storage Update Manager with Java v10.x. • The CLI command pool select default show returned an incorrect value of unknown . • Users could delete members in the maintenance pool using the CLI, but could not delete members using Group Manager. 12 Dell EqualLogic PS Series Storage Arrays Firmware Version 10.0.3 Release Notes
