Creating storage pools

This topic describes how to create storage pools.

Prerequisites

The following prerequisites must exist before you can configure storage pools:
  • There must be volumes available to create a new storage pool. If not:
    • The SAN File System administrator must request volumes from a storage device administrator.
    • The administrator of the storage device must assign metadata server engines and SAN File System clients as hosts. In addition, the administrator must allocate LUNs to be used as devices in the system storage pool to metadata server engines and LUNs to be used as data devices to the appropriate clients.
  • Only one system storage pool can exist.
  • Make sure that you add LUNs to the default storage pool.
  • You must be an administrator or IBM® support representative to perform this task.

Complete these steps to create storage pools:

Steps

  1. Using your Web browser, connect to the SAN File System Console.
  2. In the My Work frame, click Manage Storage > Create a Storage Pool. View the list of steps to create a storage pool and click Next.
  3. Under Pool Settings in the Create a Storage Pool panel, fill in the following fields:
    • Name of the new storage pool. You can enter up to 256 characters for a name, but the name must not currently exist.
    • Description of the new storage pool. You can enter up to 256 characters for a description.
    • Optionally, fill in these fields:
      • Logical partition size.
      • Allocation Size.
      • Usage threshold.
  4. Click Next to continue.
  5. Under Select Client, select a client and a fetch method to gather the available LUNs information for the next step, adding volumes to the storage pool. The default fetch method is to gather the LUN information from cache; you can also choose to rediscover the LUNs by selecting the Rediscover button. Click Next.
  6. Under Add Volumes, select the LUNs to be added from the table. Click Next.
  7. Under Volume Settings, fill in the Volume Name Prefix field, and click Next.
  8. Verify your settings, and then click Finish.
