1 Introduction Overview HP StoreOnce Backup Systems belong to a family of disk-based storage appliances for backing up media network servers or PCs to target devices on the appliance. These devices are configured as Network-Attached Storage (NAS), Catalyst Stores or Virtual Tape Library (VTL) targets for backup applications.
transferring data to the StoreOnce Backup system. Refer to http://www.hp.com/go/ebs for up-to-date details on supported applications. Hardware installation Please refer to the installation instructions provided with your product for detailed instructions on installing the HP StoreOnce Backup System and optional tape drive. Software requirements 1. 2. 3. Refer to http://www.hp.com/go/ebs to find out which versions of UNIX and Linux are supported and which backup applications are supported.
2 Linux (x86, x64 and IA64) Overview This chapter describes how to configure the HP StoreOnce Backup System for use with the following Linux operating systems: • SuSE Linux Enterprise Server 10 (x86, x64 and IA64) • SuSE Linux Enterprise Server 11 (x64 and IA64) • RedHat Enterprise Linux 5 (x86, x64 and IA64) • RedHat Enterprise Linux 6 (x64) NOTE: HP StoreOnce Backup Systems with iSCSI interfaces are only supported with SuSE Linux Enterprise Server 10 SP1 or greater and RedHat Enterprise Linux 5 or
Type: Sequential-Access st 7:0:0:0: Attached scsi tape st0 ANSI SCSI revision: 03 How to configure the Open-iSCSI module manually using the command line The command line tool for configuring the Open-iSCSI package is iscsiadm. Detailed instructions for iscsiadm can be found in the iscsiadm(8) man documents. The following instructions guide the user through the following steps required to connect a Linux host to an HP StoreOnce Backup System.
If the target is required to logon to the Initiator then the following two commands are also required: localhost:~ $ iscsiadm --mode node --targetname --portal x.x.x.x:3260 --op update –-name node.session.auth.username_in --value localhost:~ $ iscsiadm --mode node --targetname --portal x.x.x.x:3260 --op update –-name node.session.auth.password_in --value 3. The iSCSI nodes may be configured to log in automatically on system startup.
To verify that the Linux machine now has access to the target device, use the following command: localhost:~ $ cat /proc/scsi/scsi The output of this command will be a list of all the configured SCSI devices on the system, including the HP StoreOnce Backup System.
Using the following syntax, verify the mount point which lists the local mount, the remote mount, and the parameters that the target device has been mounted with: localhost:~ $ mount -v The output will be similar to the following: 16.24.160.141:/nas/Share_1 on /mnt/nfs type nfs (rw,sync,nfsvers=3,addr=16.24.160.141) Controlling an iSCSI or Fibre Channel HP StoreOnce Backup System using Linux The HP StoreOnce Backup System can appear to the Linux operating system as one of many supported emulation types.
localhost:~ $ dmesg | grep -A 4 "Ultrium" The output will be similar to this: Vendor: HP Model: Ultrium 3-SCSI Rev: pc81 Type: Sequential-Access ANSI SCSI revision: 03 2:0:0:0: Attached scsi generic sg3 type 1 st: version 20050830, fixed bufsize 32768, s/g segs 256 st 2:0:0:0: Attached scsi tape st0 In this example the SCSI tape device file that has been assigned is st0.
localhost:~ $ mtx –f /dev/sg2 load 2 0 Unloading a cartridge from a library tape drive To unload a cartridge and place it in a storage slot, the mtx unload command should be used. For example, to unload a cartridge from the first tape drive and place it in to storage slot 2, the command would be: localhost:~ $ mtx –f /dev/sg2 unload 2 0 Moving a cartridge to the library mail slot To move a cartridge to the mail slot for exporting to an attached tape drive, the mtx transfer command should be used.
Back up the Linux kernel (iSCSI and Fibre Channel) 1. Check to see what media is available.
5. Compare the original Linux kernel with the restored Linux kernel. localhost:~ $ cmp /boot/vmlinux* /temp/boot/vmlinux* If no differences are found between the two files, no message will be displayed. Backup the Linux kernel (NAS) 1. Ensure that you are in the root directory. localhost:~ $ cd / 2. Back up the Linux kernel using tar. localhost :~ $ tar cvf /kernel.tar ./boot/vmlinux* NOTE: is the path to the NFS share configured on the StoreOnce appliance.
3 HP-UX 11i v2/v3 (PA-RISC & IA64) Overview This chapter describes how to configure the HP StoreOnce Backup System for use with the following HP-UX operating systems: • HP-UX 11i v2 (PA-RISC and IA64) • HP-UX 11i v3 (PA-RISC and IA64) NOTE: A block size no larger than 256 KB is strongly recommended when working with HP-UX 11i v2. See Using large block sizes with HP-UX 11i V2 (page 23).

The response will be: Target address “x.x.x.x:3260,1” has been successfully added. 4. To display the discovery target that has been configured, type the following: # iscsiutil –pD The output will be similar to this: Discovery Target Information ---------------------------Target # 1 ----------IP Address iSCSI TCP Port iSCSI Portal Group Tag User Configured: ---------------Authenticaton Method CHAP Method Initiator CHAP Name CHAP Secret Header Digest Data Digest 5. : x.x.x.

An example of a GUI is shown below; for details of the GUI specific to your product, please refer to the product's User Guide. Output needs checking. 1. To discover operational target devices, type the following: # ioscan The output will be similar to this: H/W Path Class Description ================================================================ 0/5 ba Local PCI-X Bus Adapter (783) 0/5/1/0 fc HP AB379-60001 4Gb Dual Port PCI/PCI-X Fibre Channel Adapter (FC Port 1) 0/5/1/0.166 fcp FCP Domain 0/5/1/0.166.

To create generic devices drivers for the iSCSI target devices, using the following commands: # update_drv -ai '"scsiclass,08"' sgen # devfsadm -i iscsi 8. To verify devices files for the iSCSI target device have been created, use these commands: # ls –l /dev/scsi/changer lrwxrwxrwx 1 root root 139 Jan 2 09:51 c3t1d0 -> ../../../devices/iscsi/medium-changer@0000iqn.198603.com.hp%3Astorage.d2d.
Once configured, the Network Path is displayed. The StoreOnce Backup System supports NFSv3 protocol. By the nature of NFS protocol, there is an element of randomness in the data transmission between the client and target device, in this case, the StoreOnce NAS device. To minimize the randomness, it is recommended to use force the data transfer to be synchronous.
Verify you are controlling the correct library The robotics of the library will be assigned a SCSI device file. To discover the device file assigned, use the following command: # ls /dev/scsi/changer The response will the name of the device file. e.g. c3t1d0.Therefore, the library can be controlled using the device file /dev/scsi/changer/c3t1d0.

5 Configuring media servers for Data in Flight Encryption Introduction IP packets have no in-built security measures. As such, access to the network enables packet content to be viewed and, because no verification exists, no indication is available as to whether a packet has been viewed or content has been modified. IPsec is an OSI layer 3 protocol that provides encryption and mutual verification at the IP address level.
Data In Flight Encryption.) Create the corresponding .conf/.secrets pair and IPsec rule on the media server which backs up data to the StoreOnce Backup system. The following procedure describes the procedure for Linux servers running RHEL v5 and RHEL v6. 1. Use your operating system’s installer to install openswan. 2. Edit the /etc/ipsec.conf file to uncomment and include the /etc/ipsec.d/*.conf line at the end. 3. Create /etc/ipsec.d/storeonce.conf on the media server with the following example.
