Update FSTAB Entries to Map Mount Points to NFS Exports

Configure the FSTAB entries at each site to map the NFS exports to the directory.

Follow these steps:

Issue the CA Cloud Storage for System z Linux command to configure the FSTAB entries:
```
sudo cacloud setup
```
Select the FSTAB menu option and then map the mount points using the table that is provided at the end of this procedure.
Issue the following Linux commands to mount, unmount, or display the NFS appliance directories:
- To mount the NFS exports that are based on the current FSTAB entries:
```
sudo mount -a
```
- To unmount specific directories:
```
sudo unmount /path-to-directory
```
- To display the FSTAB entries that are currently mounted:
```
mount
```
Verify that the FSTSAB entries are defined correctly at both sites, then reboot the Linux systems using the Linux command:
```
sudo /sbin/reboot
```
Verify that the FSTAB entries are again properly mounted on each system using the Linux mount command in Step 3.

For Step 2, use the following table:

PDC FSTAB Entries	DRC FSTAB Entries
This mount point id used at the PDC for production files that replicate to the secondary appliance located at the DRC. It is mounted read/write in FSTAB and contains the Virtual Vault subdirectories. primary_url:/../pdc_mp21 /var/lib/cacloud/vault_01/mp_21 nfs rsize=131072,size=131072,nfsvers=3,intr,bg	The DRC uses this mount point to read volumes on the secondary appliance that were replicated from the PDC. It is mounted read-only in FSTAB and contains the Virtual Vault subdirectories that the PDC creates and replicates. secondary_url:/../pdc_mp21 /var/lib/cacloud/vault_01/mp_21 nfs ro,rsize=131072,size=131072,nfsvers=3,intr,bg
The PDC uses this mount point to read volumes on the primary appliance that are replicated from the DRC.
