Example 1 Saving configuration data on a Windows host
1. Double-click on the SSSU desktop icon to run the application. When prompted, enter Manager
(management server name or IP address), User name, and Password.
2. Enter LS SYSTEM to display the EVA storage systems managed by the management server.
3. Enter SELECT SYSTEM system name, where system name is the name of the storage
system.
4. Enter CAPTURE CONFIGURATION pathname\filename, where pathname identifies the
location where the configuration files will be saved, and filename is the name used as the
prefix for the configurations files: for example:CAPTURE CONFIGURATION
c:\EVAConfig\LargeEVA
5. Enter EXIT to close the SSSU command window.
Example 2 Restoring configuration data on a Windows host
If it is necessary to restore the storage system configuration, it can be done using the following
procedure.
1. Double-click the SSSU desktop icon to run the application.
2. Enter FILE pathname\filename, where pathname identifies the location where the
configuration files are be saved and filename is the name of the first configuration file: for
example: FILE c:\EVAConfig\LargeEVA_Step1A.txt
3. Repeat the preceding step for each configuration file. Use files in sequential order. For example,
use Step1A before Step1B, and so on. Files that are not needed for configuration data are
not created, so there is no need to restore them.
Adding disk drives to the storage system
As your storage requirements grow, you may be adding disk drives to your storage system. Adding
new disk drives is the easiest way to increase the storage capacity of the storage system. Disk
drives can be added online without impacting storage system operation.
Consider the following best practices to improve availability when adding disks to an array:
• Set the add disk option to manual.
• Add disks one at a time, waiting a minimum of 60 seconds between disks.
• Distribute disks vertically and as evenly as possible to all disk enclosures.
• Unless otherwise indicated, use the SET DISK_GROUP command in the HP Storage System
Scripting Utility to add new disks to existing disk groups.
• Add disks in groups of eight.
• For growing existing applications, if the operating system supports virtual disk growth, increase
virtual disk size. Otherwise, use a software volume manager to add new virtual disks to
applications.
See the disk drive replacement instructions for the steps to add a disk drive. See “Replacement
instructions” (page 73) for a link to this document.
Handling fiber optic cables
This section provides protection methods for fiber optic connectors.
Contamination of the fiber optic connectors on either a transceiver or a cable connector can impede
the transmission of data. Therefore, protecting the connector tips against contamination or damage
is imperative. The tips can be contaminated by touching them, by dust, or by debris. They can be
damaged when dropped. To protect the connectors against contamination or damage, use the
