You can run multiple instances of the Group Manager GUI in separate tabs. When running multiple GUI instances, Dell recommends that you launch the GUI instances one at a time to avoid scenarios in which multiple login dialog boxes are displayed at the same time. Otherwise, the Java virtual machine might become unresponsive and the browser application must be restarted. In Firefox, you can run only one instance of Group Manager in a browser window. JAWS Screen Reader Issues • JAWS Screen Reader Software Reads Coding Tags-When SyncRep is configured, a SyncActive volume is created as well as the SyncAlternate volume. You can disconnect the SyncActive volume by selecting a volume configured for SyncRep, Activities > SyncRep . • Attempting to disconnect the SyncActive volume opens a dialog box and the JAWS screen reader software reads the tags, such as P left brace padding..., before finishing with the contents of the dialog box. • JAWS Screen Reader Does Not Read the Validation Column in the Replica Set Placement Tab-The Manage Delegated Space - Replica Set placement tab contains a Validate Primary Pool Names button. When this button is activated, it tries to validate the pool names specified in the table with those on the partner. The Validation column of the table is updated to reflect the status of each user-supplied pool. At this time, JAWS does not read this column. • JAWS Reads HTML Tags for All Columns in Virtual Machines and Virtual Disk Tables-In VMware virtual machines, the HTML tags are read for all the columns in the Virtual machines and Virtual disk tables. Error Displays When You Run Group Parameters If you log in to the CLI as the pool administrator, and run the grpparams vss-vds access-policy show or grpparams vss-vds access- policygroup show command, the following error is displayed: Error: Too many parameters. Virtual Volumes IPv6 Virtual volumes (VVols) do not support IPv6. Do Not Modify or Delete ACLs Associated to the PE Using the CLI, users can inadvertently eliminate access to the protocol endpoint (PE), and impact their intended VVol access rules. Dell has placed many restrictions on CLI operations to prevent inadvertent misconfigurations, although they might still occur. For this reason, Dell requires the use of VSM (Virtual Storage Manager) for the creation or manipulation of ACL rules for protocol endpoints (associated with VVols). If an access rule is inadvertently removed using the CLI, it will become immediately obvious by inspecting the specific PS group being managed by VSM and navigating to the Manage > Protocol Endpoint screen. Any ESX host without access to the PE will be labeled with a red exclamation point (!). You can press the allow button to allow access again for this host or any other chosen hosts. Group Manager Does Not Display Virtual Machine Description Information The Virtual Machine description column in Group Manager displays as empty. The value can be retrieved from the vCenter UI by accessing the Summary field under the Notes tab. ESXi Support for Unmap with PS Arrays 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.

JAWS Screen Reader Issues
•
JAWS Screen Reader Software Reads Coding Tags—When SyncRep is configured, a SyncActive volume is created as well as the
SyncAlternate volume. You can disconnect the SyncActive volume by selecting a volume configured for SyncRep,
Activities

•
Attempting to disconnect the SyncActive volume opens a dialog box and the JAWS screen reader software reads the tags, such as
P

, before finishing with the contents of the dialog box.
•
JAWS Screen Reader Does Not Read the Validation Column in the Replica Set Placement Tab—The Manage Delegated Space –
Replica Set placement tab contains a Validate Primary Pool Names button. When this button is activated, it tries to validate the pool
names specified in the table with those on the partner. The Validation column of the table is updated to reflect the status of each
user-supplied pool. At this time, JAWS does not read this column.
•
JAWS Reads HTML Tags for All Columns in Virtual Machines and Virtual Disk Tables—In VMware virtual machines, the HTML tags are
read for all the columns in the
Virtual machines
and

tables.
