Snapcenter SCSQL- supported AAG and FCI Configurations



Category1: SnapCenter

Category2: SnapCenter Plug-in for SQL

Detailed Symptom: SCSQL - Supported configurations



We have three questions that need to be answered regarding the customer's current environment.


Customer have 3 SQL Availability group Instances and 1 standalone FCI SQL Instance  simultaneously running on two Node Windows Cluster (clustername COREPRDSQL16 ) .teh above config is supported by Microsoft .


 we have successfully configured the 3 SQL Availability group Instances in snapcenter and backups are running fine. However we run into  issues with discovering databases for the 1 standalone FCI SQL Instance  ( COREPRDFCI)


 This is the error message we get on the FCI:

Question#1 The account used is the same account as other AG instances with sysadmin rights in corresponding SQL instance DBS.  SVM is the same . So no storage connection issues . Why the SQL DB discovery fails.  Any things to do with static port being used for this SQL instance?





 can we run SQL AG and SQL FCI in the same Windows cluster for snapcenter ? Is this a supported configuration for SnapCenter?


Question #3  The  two nodes of the windows clusters are in 2 different datacenter locations and each windows nodes has two different IPs in two different subnets  . When we fail over teh SQL resources to the second node, we are unable to enumerate the databases on the second node.  Do we support this configuration?
