Creating arrays

Complete this task to create arrays, either automatic or custom, and to specify their RAID and rank attributes.

1. In the navigation, select Real-time manager or Simulated manager > Configure storage > Arrays. On the Arrays main page, in the Select storage unit drop-down list, select a storage unit.
2. From the Select Action list, select Create..., and then click Go. The Create Array – Definition method page is displayed.
3. In Create Array – Definition method, choose to either create your arrays automatically, where the DS Storage Manager specifies the array sites, or to create custom arrays where you specify the array sites. Click Next.
   • If you chose to create your arrays automatically, in Create Array – Array configuration (Auto), specify the quantity and RAID type of the arrays that you are creating. You can optionally select Create an 8 disk array to create an array that contains two, four-disk array sites with the same specifications. Click Next after you have made your selections. The Create Array – Add arrays to ranks page is displayed.
   • If you chose to create custom arrays, perform the following steps:
     1. In Create Array – Array configuration (Custom), specify the RAID type for the arrays that you are creating and select the array site numbers that you want to assign to the arrays. You can optionally select Create an 8 disk array to create arrays that contain two, four-disk array sites with the same specifications. Click Next after you have made your selections.
     2. If you selected to create an 8 disk array, the Create Array: Real-time – Second array-site selection page is displayed. Choose the second array site for each array that was selected in the Create Array – Array configuration (Custom) page. Secondary array sites cannot be shared among arrays. Click Next. The Create Array – Add arrays to ranks page is displayed.
        Note: When configuring two 8 disk arrays (one Raid 5, one Raid 10), you must create the Raid 10 array first and make sure that it is being created on the array sites that contain spares. Then create the Raid 5.
4. In Create Array – Add arrays to ranks, you can optionally choose to add the arrays that you are creating to ranks. If you choose to add your arrays to ranks, you must specify the storage type, FB or CKD, for the ranks that you are creating. Click Next. The Create Array – Verification page is displayed.
5. In Create Array – Verification, review the attributes and values to verify that they are correct. If the attributes and values are not correct, click Back as appropriate to return and then specify the correct values. Otherwise, click Finish to complete the array creation process.
