Configuring a SAN or a Physically Connected Disk

Connecting and formatting a disk that disk into a vxfs or ext3 file system. To configure a SAN or a physically-connected disk, follow these steps:

  1. Verify that the shared disk is not configured to be mounted at system boot time.

    The resource group is responsible for mounting the shared disk.

  2. Connect the device:

    • For a SAN disk, add the SAN device to the network.

      The logical volume on the SAN disk should be in exclusive mode, if that mode is available.

    • For a physically-connected disk, attach the disk using a Y cable.
  3. Add operating system entries to all cluster nodes (disk group, logical volume, volume group, and disk):

    • For a SAN disk, the entries reference the SAN.
    • For a physically-connected disk, the entries reference the disk hardware.
  4. Format the disk using a supported disk format. See NNMi High Availability Configuration Information for more information.
  5. Ensure that the SAN mounts.

  6. Unmount and deport the disk.
  7. To test the configuration, add the disk to a resource group and initiate failover.
