FC-Only Nimble Array Snapshot Failures in Veeam Backup & Replication P20230718
Challenge
When using Veeam Backup & Replication 12 P20230718, rescan, backup, and restore operations may fail when the Nimble array is configured to only use Fibre Channel (FC) protocol.
The request could not be understood by the server. Unexpected argument 'multi_initiator'.
Solution
A private fix is available for Veeam Backup & Replication 12 P20230718 to resolve this issue; please create a Veeam Support case and mention this KB.
Alternatively, set the Nimble storage protocol setting to "FC and iSCSI" to workaround the issue.
