6.0 HP X9720 Network Storage System Administrator Guide (AW549-96034, December 2011)

• Quotas. Configure user, group, and directory tree quotas as needed.
• Remote replication. Use this feature to replicate changes in a source file system on one cluster
to a target file system on either the same cluster or a second cluster.
• Data replication and validation. Use this feature to manage WORM and retained files.
• X9000 software snapshots. This feature is included in the X9000 software and can be used
to take scheduled or on-demand software snapshots of a file system.
• Block Snapshots. This feature uses the array snapshot facility to take scheduled or on-demand
snapshots of a file system.
• File allocation. Use this feature to specify the manner in which segments are selected for storing
new files and directories.
For more information about these file system features, see the HP X9000 File Serving Software File
System User Guide.
Logging in to the X9720 Network Storage System
Using the network
Use ssh to log in remotely from another host. You can log in to any server using any configured
site network interface (eth1, eth2, or bond1).
With ssh and the root user, after you log in to any server, your .ssh/known_hosts file will work
with any server in an X9720 Network Storage System.
The server blades in your original X9720 are configured to support password-less ssh between
them; after you have connected to one, you can reach the others without specifying the root
password again. If you wish to have the same support for additional server blades, or wish to
access the X9720 itself without specifying a password, add the keys of the other servers to .ssh/
authorized keys on each server blade.
Using the TFT keyboard/monitor
If the site network is down, you can log in to the console as follows:
1. Pull out the keyboard monitor (See “Front view of a base cabinet” (page 155)).
2. Access the on-screen display (OSD) main dialog box by pressing the Print Scrn key or by
pressing the Ctrl key twice within one second.
3. Double-click the first server name.
4. Log in as normal.
NOTE: By default, the first port is connected with the dongle to the front of blade 1 (that is, server
1). If server 1 is down, move the dongle to another blade.
Using the serial link on the Onboard Administrator
If you are connected to a terminal server, you can log in through the serial link on the Onboard
Administrator.
Booting the system and individual server blades
Before booting the system, ensure that all of the system components other than the server blades—the
capacity blocks and so on—are turned on. By default, server blades boot whenever power is
applied to the X9720 Network Storage System performance chassis (c-Class Blade enclosure). If
all server blades are powered off, you can boot the system as follows:
To boot the system:
1. Press the power button on server blade 1.
2. Log in as root to server 1.
