This alert pertains to Storage Center OS (SCOS) 6.7, 7.0, and 7.1.1. It contains specific information related to system features and/or functionality.
Alert:
In SCOS 6.7, 7.0 and 7.1.1 an issue has been determined when the ODX driver in Windows Server 2012 requests an Extended Copy between a source and destination volume within a Storage Center system. When this occurs the Storage Center does not respond with the correct ODX failure code. Without the failure code Windows will continually retry the same request which will fail. Due to the large number of failed requests, MPIO will mark the path as down.
Affected versions:
SCOS versions:
6.7.5
6.7.10
6.7.11
6.7.20
7.1.1
Workaround:
Disable ODX in Windows Server 2012 if performing ODX operations between Dell Storage Center volumes and volumes external to the array.
Resolution:
This is resolved in SCOS versions 7.1.2 and 6.7.22 and higher
