Map LUNs

Use the Map LUNs feature to map retention, backup, and optional home LUNs. You can also map LUNs that are used for any physical backup copies of a replicated pair.

Prerequisites

Before you map a LUN, consider the following points:
  • When mapping a LUN, the Oracle FS System deletes any existing host mappings for the LUN.

  • Oracle MaxRep for SAN supports third‑ and fourth‑level Linux file systems (ext3 and ext4). The Linux operating system journals the file system so that these file systems might be recovered in the event of data corruption.

  • A LUN is always mapped to an appliance initiator for the target (AIT) port group. The AIT port group is used to access the retention and backup LUNs, and optionally the home LUNs, that are mounted on the Replication Engine.

Note: The Map LUN feature is not used to map source or target LUNs that are used in replication pairs. These LUNs are mapped automatically during the Create Protection Plan process.

You can format and mount a LUN, mount the LUN if it is already formatted, or map and initiate the scanning from Oracle MaxRep for SAN.

  1. Navigate to Settings > Oracle Storage > Toolkit for MaxRep.
  2. In the Select MaxRep Option page, select Map and click Next.
  3. From the Select Oracle Storage list, choose the Oracle FS System containing the LUN that you want to map.
  4. Select the Replication Engine from the Select MaxRep list.
    Result:
    The Select LUNs for Mapping table lists the available LUNs.
  5. Expand the entry for the Oracle FS System containing the LUN.
  6. Select the LUNs for mapping and click Next.
    Result:
    A warning message displays stating that if the LUN is already mapped, your actions unmaps the selected LUN.
  7. For locally‑used LUNs, such as retention, backup, or an optional home file system, provide the Mount Point path. After mapping the LUN, the system mounts the LUN to the provided path.
  8. Specify the Format Required option. Select this option if you want the system to format the LUN after mapping.
    Note: A LUN must be formatted to mount properly.
    Caution
    Formatting removes any filesystem data from the LUN.
  9. For locally‑used LUNs, such as retention, backup, or an optional home file system, specify whether to Map to Physical FC Ports.
    Note: Oracle recommends this option for the retention, backup, and optional home LUNs.
  10. Select the Filesystem protocol that is support by the operating system.
    Note: Oracle recommends that you use the preferred file system (ext4) for local (retention, backup, and optional home) LUNs.
  11. To initiate the mapping, click Submit.
