PowerProtect Data Manager: NAS Backups of CIFS and or SMB Shares Fail With Error: ABNA0023

PPDM NAS backups of CIFS and or SMB shares fail with error ABNA0023.

ABNA0023 is a generic message used to indicate a problem with mounting either the snapshot of a share or the live share directly on a NAS proxy.

For this specific failure, the CIFS and or SMB user credentials included an exclamation mark (!) in the middle of the password which resulted in the attempt to mount the share being rejected by the NAS.

As confirmed in the documentation and testing in the Dell test labs, the exclamation mark (!) symbol is supported as a symbol that can be used in passwords by PowerProtect Data Manager, Data Domain, PowerScale, PowerStore, Unity, and all NAS systems.

However, for the affected customer environment, the password containing an exclamation mark (!) was rejected by the NAS.

Workaround:

Changing the CIFS and or SMB user credentials to remove the exclamation mark from the password addressed the problem.
