CLI – Adding or removing storage arrays

All IBM® storage systems that provide storage resources to your VMware platforms must be defined as storage arrays on the IBM Spectrum Control Base Edition.

Use the sc_storage_array CLI command to add, remove, or list these IBM storage systems (referred to as storage arrays). Use the required argument after the command, as specified in the following table.

Important:

IBM storage arrays can be added only after the storage credentials are set, as explained in CLI – Adding or removing storage array credentials.
If you want to remove existing storage arrays:
- A removed storage array, along with its storage pools and volumes, can no longer be managed by the included solution components (see Included cloud interfaces).
- If the removed storage array contains working storage pools and volumes, the information of these storage pools and volumes is no longer displayed in vSphere Web Client. However, vSphere data access and service level for these storage pools and volumes is not affected. In addition, the removed array and its storage pools and volumes can be managed from the standard IBM storage system management tools.
- After the removal, you can add the storage array back again to fully restore its management.

Note:

All CLI command arguments are case-sensitive.
The same operations are available from the GUI as well, as explained in GUI – Managing storage arrays.

Table 1. Arguments for sc_storage_array
Argument	Use after sc_storage_array to:
add -i <management IP address> -t <array type> or add --mgmt_ip <management IP address> --storage_type <array type>	Add a storage array (IBM storage system) specified by an IP address or DNS, and the type of the array. For the -t (array type) argument, specify xiv for XIV®, svc for IBM Spectrum Virtualize, Storwize®, and FlashSystem, or ds8k for DS8000®. For example: `sc_storage_array add -i 10.100.155.200 -t xiv` Optional: you can define an alias name for the added XIV system, by adding -a <alias name> or --alias <alias name> to the command. For example: `sc_storage_array add -i 10.100.155.200 -t xiv -a mystorage1` Note: If you choose not to define an alias, the alias name that is already defined (if one was defined) on the IBM storage system side is automatically assigned as the alias name.
remove -a <system alias name> or remove --alias <system alias name>	Remove a storage array specified by its alias name (alias that was given by you or was automatically assigned). For example: `sc_storage_array remove -a mystorage1`
list	List the names and details of all the IBM storage arrays that are currently added (and were not removed). The displayed information includes: Array alias Array identifier Management IP address Elapsed time since last update Connected Notes® See the example after this table.
refresh	Refresh information about all managed IBM storage arrays.
-h or --help	Display help information that is relevant to sc_storage_array. You can also display help for the add or remove argument if it is typed on the command line as well.

The following example shows the displayed information and format of the sc_storage_array list command output.
