We have a windows 2008 R2 with SQL. We configure 4 NICs connecting to target/SAN. We have some problems to access the SQL database recently. After reviewing both SAN Management console and iSCSI, we find there are only two connections show on iSCSI and SAN. Whenever we add other two connections, they are disappeared in a few seconds on both iSCSI and SAN. There are no errors in the Event Viewer and SAN log.
EqualLogic tech support says this is Microsoft issue. Also the server log event ID 16: \Device\MPIOdisk2 is currently in a degraded state. Any suggestions?
