Adding Disk Drives To The Storage System; Guidelines For Adding Disk Drives - HP 6100 User Manual

NOTE: If the storage system contains disk drives of different capacities, the SSSU procedures
used do not guarantee that disk drives of the same capacity will be exclusively added to the same
disk group. If you need to restore an array configuration that contains disks of different sizes and
types, you must manually recreate these disk groups. The controller software and the utility's
CAPTURE CONFIGURATION command are not designed to automatically restore this type of
configuration. For more information, see the HP Storage System Scripting Utility Reference.
Example 1 Saving configuration data using SSSU on a Windows Host
To save the storage system configuration:
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 command window.
Example 2 Restoring configuration data using SSSU on a Windows Host
To restore the storage system configuration:
1. Double-click on 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.

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.
CAUTION:
a disk in bays 12, 13, and 14 in enclosures 17, 20, and 24. These bays in enclosures 17, 20,
and 24 do not receive a hard assigned AL_PA. Installing a disk in any of these slots may impact
the operation of the storage system. HP also recommends that you keep three additional bays open
to maintain the maximum device count of 120. For ease of use and consistency in configurations,
HP recommends keeping bays 12, 13, and 14 open in enclosures 16 and 19.

Guidelines for adding disk drives

When adding new disk drives to the storage system, you should ensure that the disk drives are
installed in the correct positions to maintain availability. The disk drives should be distributed across
the disk enclosures to protect against the failure of a single disk enclosure.
