 Analysis on Storage

    On the storage, there is log show that the replication link is out of specification.

The replication link max number in current version is 8. The FC and the iSCSI share the quota. If the FC links occupy the all 8 quota, the later configured iSCSI link can not apply related resource and cause the failure of adding remote link.

Root Cause

The remote replication link quota is occupied by FC, make the iSCSI link invalid and the failure of adding remote iSCSI link.
