Identifying storage in a MetroCluster IP configuration

Contributors ntap-bmegan netapp-ivanad Download PDF of this page

If you need to replace a drive or shelf module, you first need to identify the location.

Identification of local and remote shelves

When you view shelf information from a MetroCluster site, all remote drives are on 0m, the virtual iSCSI host adapter. This means that the drives are accessed via the MetroCluster IP interfaces. All other drives are local.

After identifying whether a shelf is remote (on 0m), you can further identify the drive or shelf by the serial number or, depending on shelf ID assignments in your configuration, by shelf ID.

In MetroCluster IP configurations running ONTAP 9.4, the shelf ID is not required to be unique between the MetroCluster sites. This includes both internal shelves (0) and external shelves. The serial number is consistent when viewed from any node on either MetroCluster site.

Shelf IDs should be unique within the disaster recovery (DR) group except for the internal shelf.

With the drive or shelf module identified, you can replace the component using the appropriate procedure.

Example of sysconfig -a output

The following example uses the sysconfig -a command to show the devices on a node in the MetroCluster IP configuration. This node has the following shelves and devices attached:

  • slot 0: Internal drives (local drives)

  • slot 3: External shelf ID 75 and 76 (local drives)

  • slot 0: Virtual iSCSI host adapter 0m (remote drives)

node_A_1> run local sysconfig -a
