Dell Unity: How to Rename an Existing LUN or Data Store using UI or CLI
Summary: This article describes the process of how to rename an existing Block Storage resource using either Unisphere or UEMCLI.
Instructions
During provisioning of LUN resources (including VMware Data Store), the storage resources get mapped through its World Wide Name (WWN) which behaves like a Unique identifier. The LUN name during the creation is considered as a user identifier for administrators to identify and manage it. It is safe to rename an Existing resource, as the WWN is not getting updated or altered during this process.
WWN can be viewed from the LUN Properties:
Figure 1: UI - Host Access LUN Properties
To rename from the UI
Edit the Name field in the Properties, then Save or Apply:
Figure 2: UI General Properties Rename
To rename from uemcli:
Edit the block resources name with the below command. The following command updates LUN lun_1 with Name as NewName:
Syntax:
uemcli -d <managemenet_ip> -u <local/ldap_user>-p <specefied_user_password> /stor/prov/luns/lun -id <LUN_ID> set -name <new_name_to_be_reflected>
For example:
uemcli -d 10.0.0.1 -u admin -p MyPassword456! /stor/prov/luns/lun -id lun_1 set -name NewName To get the LUN id, use below command: uemcli -d 10.0.0.1 -u admin -p MyPassword456! /stor/prov/luns/lun show To edit the VMware vStorage VMFS resources: uemcli -d 10.0.0.1 -u admin -p MyPassword456! /stor/prov/vmware/vmfs –id VMFS_1 set – name Accounting4

The World Wide Name (WWN) acts as a unique identifier and is not affected by the renaming process.
