Display Screen With Wireless Display Adapter Connected

Last week a Microsoft Wireless Display Adapter turned up in the post. I’ve tried some wireless PC display connectors before, and the general rule seemed to be they were clunky, unreliable, and not that user friendly. This however, changes that. This is WiDi/ Miracast as it should be; easy to set up and simple to use.

Failure to Create Diagnostic Logs on EqualLogic

Symptoms

When running the diag command from the Dell EqualLogic CLI (via a SSH session to an EqualLogic member) the process proceeds as normal but never completes, and the SSH session is eventually terminated. Repeating the operation produces the same result.

Example Output:

login as: grpadmin

EQxxxxx> diag
The diag command will gather configuration data from this array
for support and troubleshooting purposes. No user information will be
included in this data.
Results will be sent to "xxxxx" through email.
If this is unsuccessful, other options for retrieving the results
will be presented at the end of the procedure.
Finally, please remember to include your Dell Technical Support case or incident number
in the subject line of any email that you send to Dell Support. This will help
ensure that the message is routed correctly.

At which point there is no further output and the SSH session is disconnected

Cause

The cause is as yet unknown (to me at least), but the symptoms are possibly due to some left over files in the target directory.

Solution

Check another admin is not trying to run diagnostics on this member at the same time. Then use the file transfer tool that would be used to retrieve the files (WinSCP for example) to connect to the EqualLogic member as grpadmin and remove the Seg_*.dgo files (preferably copying them to a temporary folder on your workstation first just in case). Finally repeat the diag command from a new SSH session (again, logged in as grpadmin) and the process should complete.

Background Notes

Based on symptoms I encountered on two EqualLogic hosts, one running v7.1.5 firmware and one running v7.1.9 firmware. Both incidents were resolved by this method in my case but no guarantees!
