5.1.5 Silent installation procedure of Storage Cruiser's agent (for Solaris)

A silent installation is a method of loading the required information for installation from a pre-created install parameter file to install software automatically without requiring user interaction at the time of installation.

Take the following steps for silent installation:

Edit an install parameter file
Run a silent installation.

Note

Silent installation does not support the version upgrade installation function.
For version upgrade installation, refer to the ETERNUS SF Migration Guide of this version.

5.1.5.1 Editing install parameter file

An install parameter file is a file in which to specify an installation destination directory. This file is stored on DVD-ROM and default values are set to respective install parameters. For details on the install parameter file, refer to "D.11 Solaris Install parameter file (for Storage Cruiser's agent)".

The install parameter file is stored on the DVD-ROM "ETERNUS SF SC/ACM/Express Mediapack (Agent Program and Manual)" of this version.

Storage location

dvdromMountDir/Agent_unix/Storage_Cruiser/Solaris/scagt_parameter.txt

When installing with default install parameter values, no editing is required.
When changing install parameters, copy the install parameter file on the DVD-ROM to an optional location and edit the copied file. For description of each install parameter, refer to "D.12 Solaris Install parameters (for Storage Cruiser's agent).

In this manual, installing using the default install parameter values is referred to as "Default install" and nstalling with edited install parameters is referred to as "Custom install".

5.1.5.2 Running silent installation

The procedure to silently install Storage Cruiser's agent (for Solaris) is as follows:

Log in to the target server. Perform the post-login operation as root (superuser).
Install the DVD-ROM "ETERNUS SF SC/ACM/Express Mediapack (Agent Program and Manual)" of this version into the DVD-ROM drive to mount the DVD-ROM media.
In the following example of command execution, the device name of the DVD-ROM drive is mounted as /dev/dsk/c0t4d0s0. The device name of a DVD-ROM drive varies with the device:
```
# mount -F hsfs -o ro /dev/dsk/c0t4d0s0 dvdromMountPoint
```
Execute the following silent installation command.
- For default install:
  For installLogFile, specify the file in which to output installation log with an absolute path. It is optional to specify for installLogFile.
```
# dvdromMountPoint/Agent_unix/Storage_Cruiser/Solaris/scagtsilentinstall.sh [-l installLogFile]
```
- For custom install:
  Specify for installParameterFile with an absolute path. It is mandatory to specify for installParameterFile.
  For installLogFile, specify the file in which to output installation log with an absolute path. It is optional to specify for installLogFile.
```
# dvdromMountPoint/Agent_unix/Storage_Cruiser/Solaris/scagtsilentinstall.sh -s installParameterFile [-l installLogFile]
```
Point
- If nothing is specified for installLogFile, an install log file named "scagtsilentinstall.log" is created in /var/tmp directory.
- If there is any file of the same name as the specified install log file exists, it is overwritten.
- It is required to specify an existing directory with write permission for the directory in which to store the install log file. If it has no write permission, no error message is output in the command prompt or screen, and the process terminates with error.
Note
- If an invalid option is specified, its corresponding error message is output in the install log file and the process exits. No error message is output in the command prompt or screen.
- Do not execute multiplexly the command for silent installation. If it is multiplexly executed, the command executed after that will terminate abnormally. At this time, an install log file is not created.
On completion of installation, a command prompt is displayed.
Move to any directory other than the directory on the DVD-ROM. The example of move is as follows:
```
# cd /
```
Unmount the DVD-ROM.
```
# umount dvdromMountPoint
```
Remove the DVD-ROM media out of the DVD-ROM drive.
