This happens if the name provided on the PowerStore's add remote system wizard does not match the name set up on the XtremIO system.

---

Use the real XtremIO's name on the Wizard.
The XtremIO cluster name can be found:

• Using the XtremIO web interface, under Inventory > Clusters
• Using the CLI with the command: xmcli (tech)> show-clusters

---

Import requirements and restrictions are listed in the Importing External Storage to PowerStore document on https://www.dell.com/powerstoredocs.

If the XtremIO remote system reports a complete data connection loss after successfully adding it to the PowerStore, and you can ping the iSCSI ports, verify that connectivity on both management and storage network between the XtremIO and PowerStore is working, and login credentials are valid.
PowerStore uses the replication-tagged network for imports.


If you have to change the replication tag to a different network, remove the XtremIO remote system, change the replication tag, and then add it again.
