Avoid double encryption
Encryption and decryption at the storage device level does not affect the
encryption switch or blade capabilities, and does not cause problems with
decrypting the data. However, double encryption adds the unnecessary need to
manage two sets of encryption keys, increases the risk of losing data, may reduce
performance, and does not add security.
Verifying correct operation and backing up the configuration
To verify correct operation and to back up the system, follow these steps.
1.
Check the LEDs to verify that all components are functional. For information
about LED patterns, see Chapter 4, “Monitoring system components,” on page
53.
2. If necessary, log on to the switch by Telnet, using the admin account.
3.
Verify the correct operation of the system by entering the
switchShow
command
from the workstation. This command provides information about switch and
port status.
4. Verify the correct operation of the SAN768B-2 in the fabric by entering the
fabricShow command from the workstation. This command provides general
information about the fabric.
5. To back up the configuration, run the following two steps:
a.
Enter the
configupload -vf
command. This command uploads the system
virtual fabric data.
b. Enter the
configupload
command. This command uploads the system
configuration.
6.
Run the following commands to see more configuration information that you
can then copy to a file to save:
v configShow
v ipAddrShow
v licenseShow
v switchShow
Alternatively, you can save the configuration file to the USB device by using the
usbStorage
command.
Note: Passwords are not saved in the configuration file, and are not uploaded
during a
configUpload
. Save password information in hardcopy in a secure
location for emergency reference, subject to your security and password
management policy.
Note: IBM recommends that you back up the configuration regularly to ensure
that a complete configuration is available for downloading to a replacement
system.
Fabric OS firmware updates
To ensure optimum functioning of your system, IBM recommends operating your
system with the latest Fabric OS version and firmware updates. Refer to the latest
Fabric OS Release Notes for information regarding Fabric OS compatibility. This is
particularly important for fabrics with 1-Gbps switches using earlier Fabric OS
versions. Detailed information on downloading and installing firmware are
provided in “Downloading firmware from an FTP server” on page 94 and
50
