Symptoms

A user configured a new storage network (for example, a second storage network for replication).The option for removing or deleting that network is unavailable in PowerStore Manager:Possible errors and messages: PowerStore MAnager: hover over message shows: The selected network is in use and cannot be deleted.PSTCLI: Network XYZ could not be deleted since it is mapped to IP ports: IP_PORT1, IP_PORT2. Unmap all ports from the network before deleting it (0xE0E200702003).PSTCLI: The IP port IP_PORTx cannot be removed from the use by Storage network because it is used for External Replication (0xE0E250701005).

Cause

The network cannot be removed if it is in use (tagged for replication or mapped to any ports).

Resolution

In order to delete or remove a second storage network, you must: Move the replication tag to any other existing storage network: PowerStore Manager > Hardware > APPLIANCES > Click your appliance > PORTS tab > select the new storage network to tag for replication > MORE ACTIONS > Tag for Replication Remove the storage network from all network ports. ATTENTION: Only do this if you are sure that nothing is using this network. PowerStore Manager > Hardware > APPLIANCES > Click your appliance > PORTS tab > select the new storage network to tag for replication > MORE ACTIONS > Remove Mapping Remove global discovery IP (GDIP) (if there is one set up). Settings > Networking > Network IPs > STORAGE > Select the storage network > MORE ACTIONS > ReconfigureNOTE: Deleting the global discovery IP (GDIP) in PowerStoreOS version 3.5.x.x is not possible. This is resolved in PowerStoreOS version 3.6.0.0 and later.PowerStore CLI (pstcli) is installed on each PowerStore Node, and can be used to delete the network.pstcli -d PowerStoreClusterManagementIP -u admin network showpstcli -d PowerStoreClusterManagementIP -u admin network -name StorageNetworkName delete Delete the network.
