HP StorageWorks 9100 Extreme Data Storage System administration guide V1.0.2 (AN540-96018, February 2010)

9. If you configured Samba, create symbolic links in /etc/samba as described in Configuring and
using Samba on page 69.
10. If you made any other customizations to other servers, you may need to apply them to the newly
installed server.
Adding storage blocks
Additional storage blocks can be added to an existing system while the system is still running. One
or more storage blocks can be added at a time, up to the point where the system has the maximum
number of storage blocks.
Additional storage blocks will be pre-provisioned in the factory with the standard LUN layout and
storage block settings (for example, rebuild priority). Parity initialization will have completed on all
LUNs. The LUNs will be blank and will not have been formatted as PSFS filesystems.
Instructions for adding a storage block are shipped with the new storage block and can also be found
at: http://www.hp.com/go/exds/support, and then click the Manuals link.
After the new storage block is physically installed in the rack and connected, use the following steps
to complete the installation:
1. Power on the storage block by first powering on the ExDS9100cx enclosure followed by the
ExDS9100c enclosure.
2. Run the exds_stdiag command to validate that the new storage block is visible and that the
correct firmware is installed. See The exds_stdiag utility on page 149 for more information on in-
terpreting the output from exds_stdiag.
3. If necessary, update the firmware of the new storage block. See Upgrading HP ExDS9100cc,
HP ExDS9100cx I/O module, and disk drive firmware on page 126 for instructions on how to
update the firmware.
4. Run the discover storage command as follows:
# exdsmgr discover storage
The new storage block is assigned an array number. Use the exdsmgr show array command
to view information about the new storage block.
If the exdsmgr discover storage prompts you to identify the physical location of the new
storage block, then you can skip to the next step. Otherwise run the exsmgr identify
storage command. This command will update the database with the physical location of the
storage block. It will also verify that the left and right drawers of the ExDS9100cx are correctly
connected to the ExDS9100c.
5. If the storage block being added is storage block 2 or 3 (that is, the original system contained
one or two storage blocks only), follow these additional steps:
a. Shut down the system so only one server is running.
b. Run the following command:
#exdsmgr reconfigure matrix
6. The storage block is pre-configured in the factory with data LUNs; however, there are no
filesystems on the storage block. See Creating a filesystem on page 59 for instructions on how
to create filesystems on the new storage block.
7. If this system exports filesystems, you can add the new filesystem using the exdsmgr modify
vnfs command. See Modifying a VNFS configuration on page 65 for instructions.
