Installation

To install the CA Cloud Storage for System z server, follow these steps:

Log in to Linux on System z.
Create a user download directory or identify your standard software download directory.
Download the latest cacloud and ctcl rpms for CA Cloud Storage for System z from CA Support to your directory. Use the following naming convention for these rpms:
```
product-version.release-modification.platform.rpm
```
Install the ctcl rpm from the download directory to create:
```
/lib/module/$(uname -r)/cavtape/ctcl.ko. 
```
Use the installation command:
```
sudo rpm -ihv ctcl-cacloud.r-m.s390x.rpm
```
Verify the installation using the following command:
```
/sbin/modinfo ctcl
```
Install the cacloud rpm from the download directory to:
- Create a cacloud user and group (uid/gid=325).
- Install the Linux Server, support scripts, and configuration files.
- Define the Virtual Volume Vault Directory (Vault).
Use the installation command:
```
sudo rpm -ihv cacloud-v.r-m.s390x.rpm
```
Verify the installation using the following command:
```
cacloud help 
```
Mount the network storage disk device to the appropriate CA Cloud Storage for System z Virtual Volume Vault directory. The cacloud rpm created /var/lib/cacloud/vault_01/mp_nn where nn is 01, 02, 03, and 04. You can use each mount point for a different type of network storage disk device with different storage characteristics. You can define more Virtual Volume mount point subdirectories.
Start the Linux Server using the following command:
```
sudo cacloud start
```
Use the following z/OS console command to check connectivity, if you have already installed, configured, and started <tape> on z/OS:
```
SVTn X PING 
```
Read Channel-to-Channel Overview and Definition and Mount Point Planning.
Perform the steps shown in Configuration.

Upgrading RPMs

Upgrading RPMs lets you preserve any customization that you performed as part of the initial RPM installation.

To upgrade RPMs, follow these steps:

Use the following command to determine your current rpm maintenance level:
```
rpm -qi cacloud ctcl
```
Go to CA Support to determine if a higher version exists. The version release and modification level are embedded in the rpm file name.
Download the higher version, if it exists, and apply it with the following command:
```
sudo rpm -U product-version.release-modification.platform.rpm
```
Reboot the Linux server when upgrading the ctcl rpms. Use the following command:
```
sudo /sbin/reboot
```
Restart the Linux server when updating the cacloud rpms. Use the following command:
```
sudo cacloud restart 
```
