Hello,   At my current environment we are planning on upgrading from ONTAP Version 9.1P2 to 9.3P19. That is all fine and dandy, but if we had to revert for whatever reason we would have to go to 9.2P4. I know there is a bug with certificates if upgrading, link below. My question is, would we even be able to revert given we wouldn't even be able to upgrade to the version? Does a reversion check and stop if the certificates aren't valid? For context we are running 1 HA pair of FAS2552 devices.   https://mysupport.netapp.com/NOW/cgi-bin/bol?Type=Detail&Display=1250500   ,Thanks ... View more

For failed disks that still can be unfailed we use disk sanitization for wiping out any data before we return the disk to NetApp. To use disk sanitization we had to activate the option "licensed_feature.disk_sanitization.enable". After activation, this option can't be deactivated anymore. This is clearly documented in the command reference of the option. In contrast to this the documentation of the sanitazation is very vague in regard to the consequences: "Attention: After disk sanitization is enabled on a storage system, it is permanent, and it prevents certain Data ONTAP commands from being run." (Storage Management Guide) We had to painfully learn that one of the commands that is prevented from being run is the vol move command. Before activating the option we used vol move without problems. Afterwards it threw an error message saying that vol move requires a Snapmirror license now. In a case opened for this it was pointed out that this was for security reasons. Since we do not use Snapmirror we didn't have a licence and had to procure it. After adding the license vol move worked fine again. This occured with 7-Mode ONTAP 8.1.3 and I requested a documentation update on this. But it hasn't been incorporated in 8.3.1 yet. Question: Are there any experiences on what doesn't work in conesquence of activating the disk sanitization option? ... View more

after mounting a CIFS share on a linux system (rhel8, fully patched) i sometimes get:    CIFS: VFS: sign fail cmd 0x8 message id 0x107ebf  CIFS: VFS: \\FILER\SHARE SMB signature verification returned error = -13   the mount seems to work, but i dont know if this is true for every access.   there exists an KB article at https://kb.netapp.com/on-prem/ontap/da/NAS/NAS-KBs/SAMBA_Client_returns_SMB_signature_verification_error   where i'm advised to use nfs instead. seriously? CIFS and NFS are NOT interchangeable. eg. complex permission sets dont translate from one to another.   there seems to be an old KB at https://www.suse.com/support/kb/doc/?id=000020670 where suse recommended to upgrade from 9.5.P13 to ontap 9.5P14 maybe just a similar error, and not the same. hopefully not the same 🙂 I dont have any clue which bug/feature was fixed in 9.5.P14     ...
