I am resetting all local NetApp cluster passwords to upgrade the hash from MD5 to SHA512 and I am down to my last one - the local service account used by SnapDrive for the Transport Protocol Settings. We only have SnapDrive running on Windows Failover Clusters, and only for LUN management (due to a SnapCenter bug I'm awaiting a fix on). We use SnapCenter on all systems, including the ones with SnapDrive, for backups.
Within this context, is there any risk to changing the password for the service account used in the Transport Protocol Settings dialog box, and then going one system at a time to update the new password in the dialog box? I don't want to get in a situation where (a) SnapDrive tries to connect and it affects LUN functionality, and/or (b) SnapDrive tries to connect from systems I haven't updated the password for yet, and it locks out the service account.
Any recommendations?
