2 Installing and Configuring MSA Arrays
This chapter summarizes the installation and configuration steps for MSA2000fc arrays usee in
HP SFS G3.1-0 systems.
2.1 Installation
For detailed instructions of how to set up and install the MSA2000fc, see Chapter 4 of the HP
StorageWorks 2012fc Modular Smart Array User Guide on the HP website at:
2.2 Accessing the MSA2000fc CLI
You can use the CLI software, embedded in the controller modules, to configure, monitor, and
manage a storage system. CLI can be accessed using telnet over Ethernet. Alternatively, you can
use a terminal emulator if the management network is down. For information on setting up the
terminal emulator, see the HP StorageWorks 2000 Family Modular Smart Array CLI Reference Guide
on the HP website at:
NOTE:
The MSA2000s must be connected to a server with HP SFS G3.1-0 software installed as
described in
to use scripts to perform operations on multiple MSA2000
arrays.
2.3 Using the CLI to Configure Multiple MSA Arrays
The CLI is used for managing a number of arrays in a large HP SFS configuration because it
enables scripted automation of tasks that must be performed on each array. CLI commands are
executed on an array by opening a telnet session from the management server to the array. The
provided script, /opt/hp/sfs/msa2000/msa2000cmd.pl, handles the details of opening a
telnet session on an array, executing a command, and closing the session. This operation is quick
enough to be practical in a script that repeats the command on each array. For a detailed
description of CLI commands, see the HP StorageWorks 2000 Family Modular Smart Array CLI
Reference Guide.
2.3.1 Configuring New Volumes
Only a subset of commands is needed to configure the arrays for use with HP SFS. To configure
new volumes on the storage arrays, follow these steps:
1.
Power on all the enclosures.
2.
Use the rescan command on the array controllers to discover all the attached enclosures
and drives.
3.
Use the create vdisk command to create one vdisk from the disks of each storage
enclosure. For MGS and MDS storage, HP SFS uses RAID10 with 10 data drives and 2 spare
drives. For OST storage, HP SFS uses RAID6 with 9 data drives, 2 parity drives, and 1 hot
spare. The command is executed for each enclosure.
4.
Use the create volume command to create a single volume occupying the full extent of
each vdisk. In HP SFS, one enclosure contains one vdisk, which contains one volume, which
becomes one Lustre Object Storage Target (OST).
To examine the configuration and status of all the arrays, use the show commands. For more
information about show commands, see the HP StorageWorks 2000 Family Modular Smart Array
CLI Reference Guide.
