Moving the /store file system to a Multipath Fibre Channel Solution

In JSA, you can implement multipath Fibre Channel. If you experience a storage area network or SAN switch issue, multipath provides extra redundancy to prevent disruption to flow and event data.

Ensure that you completed the following tasks:

  1. Log in to your JSA Console as the root user, using SSH.
  2. Identify a storage area network (SAN) partition by typing the following command:
  3. Stop the JSA services by typing the following commands in the order specified:
  4. Unmount the file systems by typing the following commands:
  5. Create a /store_old directory by typing the following command:
  6. Determine the Universally Unique Identifier (UUID) of the device partition by typing the following command:
  7. Edit the /etc/fstab file.
    1. Replace the /store mount point with /store_old.
    2. Add the new /store mount point.

      If the file system is XFS and you are not using HA, add the following text:

      If the file system is XFS and you are using HA, add the following text:

      If the file system is ext4 and you are not using HA, add the following text:

      If the file system is ext4 and you are using HA, add the following text:

  8. Mount the file systems and copy the data to your device by typing the following commands:
  9. Start the JSA services by typing the following commands in the order specified:
  10. Enable Fibre Channel multipath by typing the following command:
  11. Remove the local copy of /store by typing the following command:
