MDT-195104 SupportAssist
There is a known issue with the ‘Sent to Support’ field of the Support Materials
settings page. When a “SEND TO SUPPORT” action is taken against a Data
Collection, the “Status” field will be set to “UPLOAD SUCCESSFUL”. And the “Sent
to Support” field will be given a timestamp almost immediately. This information
really applies to the fact that the process has been initiated, and the file upload
has begun, not that the upload has completed. Once the data upload to support
has been completed (“Which may take up to 24 hours or more”), the “Sent to
Support” timestamp may change to reflect the actual upload completion time.
The implications of this is that if asked to send support materials to support, they
may not have been received at the time of the timestamp. Work with your
Support representative to verify that your materials have been received.
MDT-146912 Virtualization
In PowerStore X model, when both ESXi hosts of the appliance are rebooted
simultaneously (for example, due to a power failure), ESXi iSCSI parameters (path
selection policy, Round Robin IOPS limit, number of outstanding IOs with
competing worlds) of one or both nodes may be reset to the default ESXi values.
This may affect IO performance.
