증상

A host may lose access to volumes after PowerStore upgrade to the affected version.

Alternatively, if PowerStore was previously upgraded to the affected version without any issues, updating the host drivers to a version supporting NVMe exposes this issue.

원인

After the hosts are updated to support NVMe, a second process login (PRLI) can occur from the host following each link up event. This second PRLI is for NVMe transport, and the PowerStore does not handle this second PRLI optimally.

해결

This issue is addressed in PowerStoreOS v3.

Workaround:
Disable NVMe support in the driver.
