Configuring a reserved LUN pool for the storage processors

In the EMC Navisphere Web interface, do the following.

To configure a reserved LUN pool for the storage processors

  1. Under the node for your array, right-click Reserved LUN Pool and choose Configure.
  2. In the Configure Reserved LUN Pool dialog box, under Available LUNS, select the LUNs to be added to the reserved LUN pool.

    The reserved LUN pool must contain at least one LUN for each source LUN.

  3. For FLARE versions before 2.24, click the Add to SPA LUN Pool for storage processor A or Add to SPB LUN Pool for storage processor B.

    Check the properties of the source LUN to determine the storage processor that owns it.

  4. Click Ok or Apply.

    Each reserved LUN pool node shows how much space is free in the pool.

    The amount of space that the reserve LUN pool requires depends on how many unique blocks change in the source LUN during the life of the snapshot. If little space remains in an existing LUN pool, add new LUNs to the LUN pool.

    Generally, the more snapshots that are created, the more space that is required in the reserved LUN pool. If the LUN pool space is used up, snapshots attached to backups may become inactive and future snapshot backups fail.
