Copying the FlashSystem V840 software update files using PuTTY scp

PuTTY scp (pscp) provides a file transfer application for secure shell (SSH) to copy files either between two directories on the configuration node or between the configuration node and another host.

Before you begin

To use the pscp application, you must have the appropriate permissions on the source and destination directories on your respective hosts.

About this task

The pscp application is available when you install an SSH client on your host system. You can access the pscp application through a Microsoft Windows command prompt.

Complete these steps to use the pscp application:

Procedure

Start a PuTTY session.
Configure your PuTTY session to access your FlashSystem™ V840 clustered system (system).
Save your PuTTY configuration session. For example, you can name your saved session SVCPUTTY.
Open a command prompt.
Issue this command to set the path environment variable to include the PuTTY directory:
```
set path=C:\Program Files\putty;%path%
```
where C:\Program Files\putty is the directory where PuTTY is installed.
Issue this command to copy the package onto the node where the CLI runs:
```
pscp -load saved_putty_configuration
directory_software_upgrade_files/software_upgrade_file_name
username@cluster_ip_address:/home/admin/upgrade
```
where saved_putty_configuration is the name of the PuTTY configuration session, directory_software_upgrade_files is the location of the software update files, software_upgrade_file_name is the name of the software update file, username is the name that you want to use on the FlashSystem V840, and cluster_ip_address is an IP address of your clustered system.
Note: Saving the PuTTY configuration session in step 3 and then loading the PuTTY configuration session in step 6 is optional. To copy without loading a PuTTY configuration session, use the following syntax:
```
pscp directory_software_upgrade_files/software_upgrade_file_name
username@cluster_ip_address:/home/admin/upgrade
```
If there is insufficient space to store the software update file on the system, the copy process fails. In this case, complete the following steps:
1. Use pscp to copy data that you want to preserve from the /home/admin/update directory.
2. Use the following command to delete dump files in the /home/admin/update directory:
```
 cleardumps -prefix /home/admin/upgrade
```
3. Repeat step 6.
