Add SAN Storage

Procedure

1. In the navigation pane, choose Inventory > Data Storage.
2. Select the target data center and click Actions > Add Data Storage.
3. In the Add Data Storage dialog, configure the following options:

   Basic Information

   Option	Description
   Name	Enter a name for the SAN storage.
   Description	Enter a brief description for the data storage.
   Type	Select SAN Storage.
   Data Center	Displays the data center that contains the SAN storage.

   Configurations

   Option	Description
   Cluster	Select the cluster where the SAN storage will be attached.
   Default Provisioning Method of Storage Space	Specify the allocation method for disk storage space. Default: Thick Provision. Thick Provision: Pre-allocates the required storage space to provide sufficient capacity and ensure storage performance. Thin Provision: Allocates storage space according to actual usage for higher storage utilization.
   Storage Addition Method	Select a method to add storage. New: Creates new data storage by initializing unused LUNs into data storage that can be used by the platform. You can choose whether to clear existing data on the LUNs when adding them. Register: Imports LUNs that already contain data, such as storage migrated from another platform or replicated through disaster recovery, into the platform. The platform identifies the SAN storage structure and repairs metadata. During registration, all LUNs under the SAN storage are added automatically.
   LUN	Select LUNs provided by iSCSI storage, FC storage, or NVMe storage.
   Storage Network	Specify a storage network for shared storage. The platform uses this storage network to check the health status of virtual machines.
   Cleanse LUN	Choose whether to forcibly clear existing data on the LUNs, such as file system, RAID, or partition table labels. By default, the LUNs are not cleansed. Note: If data or partitions exist on the LUNs, adding LUNs or attaching data storage might fail.
   Storage UUID	When you select Register as the storage addition method, specify how to handle the storage UUID. Keep: Retains the original UUID of the SAN storage. Reset: Regenerates a UUID for the SAN storage. This option applies to scenarios such as UUID conflicts after cloning or snapshots, or disaster recovery drills where the storage must be decoupled from the production environment. After reset, the original UUID becomes invalid. If other hosts still use the original UUID to access the storage, I/O errors occur.

4. Review the configuration and click OK.
