Deploy or attach of a vSCSI attached virtual machine fails

Use this information if a virtual SCSI (vSCSI) deploy or attach fails with this error message NV-D855351 Unable to attach storage None to virtual machine ml184-f8a2989a-00000005. Error getting information from the Virtual I/O Servers. This could be because it is down or too busy to process the request.


This could happen if there are too many requests being sent to the Virtual I/O Server and it is taking time to respond.


To resolve this problem, filter out the Fibre Channel ports that will not be used. To do this, access the PowerVC user interface, then go to Configuration > Fibre Channel Port Configuration and change connectivity to None for any ports that should not be used.
