Release Notes

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.
