Bug 32243513 ZFS Storage Appliance Writing One LUN (STMF) Property Clears the Other During Conversion (Doc ID 2890134.1)

Symptoms

Any LUNs created prior to applying the deferred update in 8.8.22 (Deferred Update: Improved LUN Attach and Detach Performance, Introduced in 2013.1.8.22 GA), within the range of versions affected, noted below, and where LUN properties were changed at some point after initial creation, would be susceptible to this issue.

In order for the symptoms to be triggered, some update to the LUN properties would have needed to occur, either by an administrative action or via a SCSI mode select from a client. Once that update occurs, the LUN properties are cleared and upon re-import (either by reboot or a restart of akd), the LUN would have default options applied. Initiatorgroup, targetgroup, assignednumber and status would be reset from the values the customer had previously set.

As long as the system is not rebooted or akd restarted, the kernel would still have the correct values for those properties and therefore, the system would continue to function without issue. However, viewing these properties (Initiatorgroup, targetgroup, assignednumber and status) via the ZFS Storage Appliance (ZFSSA) UI, would report those LUN properties as empty.

To identify and reinstate the previous LUN property values, please contact Oracle Support or open a new Service Request via My Oracle Support (MOS).
