PowerStore: "Encountered an irrecoverable error during command execution"

Mapping File Mobility Network IPs fails:
Encountered an irrecoverable error during command execution, Reason obj_not_found (0xE04020040004)

This issue can occur if the user reconfigures the management network and changes the MTU from the default value of 1500 to some other value and then tries to create and map File Mobility Network IPs. The mapping of File Mobility IP addresses fails with the 'irrecoverable error' issue shown above.

This issue affects PowerStoreOS versions 3.2 and 3.5 and will be resolved in a future PowerStoreOS release.
As a workaround, users must remove their File Mobility Networking IPs and revert management network MTU settings back to 1500. Finally, re-create the File Mobility Network IP addresses, and map the IPs to the management network.
