removal of hmac-ripemd160 from OnTap 9.1p7

Hi,

Could some one help me on this. We are planning to upgrade our OnTap 9.1 p7 to 9.3. during the image validation, I got the below warning. Could you please let me know if we remove the mentioned MAC algoritham from the existing setup, will it cause any issue, post upgrdate.

Openssh 7.2 upgrade   Warning    Warning: "hmac-ripemd160" and

precheck                         "hmac-ripemd160-etm" are considered weak

                                 keyed-hash message authentication code

                                 (HMAC) algorithms and support for the same

                                 will be removed after upgrading to Data

                                 ONTAP 9.3.

                                 Action: Before retrying the upgrade, remove

                                 the above weak algorithms using "security

                                 ssh remove" command. To list all Vservers

                                 configured with one or both the above HMAC

                                 algorithms, run "security ssh show

                                 -mac-algorithms hmac-ripemd160* -vserver *

                                 -fields vserver" .

Thanks,

Senthil
