MDS9000 - DS-X9032-SSM |
Problem Description
License install causes applications using Write Acceleration to fail in DS-X9032-SSM.
Background
This issue is caused by a license conflict.
Problem Symptoms
If you install a feature license on any module, the storage services module DS-X9032-SSM with the SCSI flow feature will be reprovisioned and write acceleration on the flows will be affected.
For example, if you have a switch with a DS-X9032-SSM card installed with write acceleration configured, then add a DS-X9302-14K9 card, when you enable the license for the DS-X9302-14K9 card, this will disrupt the write acceleration data flow on the DS-X9032-SSM card.
Workaround/Solution
To recover from this issue, please follow these steps:
-
Enter the shutdown command to shut the host and storage ports that are using the SCSI flow.
-
Enter the no scsi-flow flow-id flow-id command to remove the SCSI flow.
-
Enter the no ssm enable feature scsi-flow force module slot-number command to unprovision the SCSI flow. This will reload the module.
-
When the module is up, enter the ssm enable feature scsi-flow module slot-number command to enable the SCSI flow feature.
-
Reconfigure the SCSI flow.
This issue has been fixed in SAN-OS release 3.1.3a and onwards.
